What is the difference between rubber and latex? Which is better?

First, the nature is different:

1.Latex is a milky, flowing liquid that looks like milk. Latex is a biosynthetic product. Due to the differences in tree species, geology, climate and other related conditions, its composition and colloidal structure vary greatly.

2.Rubber is a natural polymer compound with polyisoprene as the main component. 93% of its composition is rubber hydrocarbons, the rest is protein. Natural rubber is the most widely used general-purpose rubber.

Second, the use is different:

1.Latex is a liquid that comes out when the rubber tree is knocked out. It is milky white and ammonia and other stabilizers are often added to prevent the natural rubber latex from curing due to the action of microorganisms and enzymes.

2.Rubber is the basic raw material of the rubber industry, and is widely used in the manufacture of rubber products such as tires, hoses, tapes, cables, etc. It is an important material, equivalent to metals, chemical fibers, and plastics.

Third, the usage is different:

1.Common latex products: sponges, gloves, pacifiers, rubber hoses.

2.Common rubber products: tires, basketballs, table tennis rackets.

Extended information: Latex properties.

1.Concentrated. The concentration of latex is expressed in terms of total solids content and dry gel content. Dry rubber content refers to the content of dry rubber in latex, while total solids content refers to the content of all solid substances in latex after removing water and volatile components, expressed as a percentage.

2.Relative density.

The relative density of fresh latex is approximately determined by the relative density of whey (and rubber hydrocarbons). The amount of rubber hydrocarbons in latex can be measured approximately from the relative density. The higher the rubber content, the smaller the relative density of latex, as shown in the table.

3.Viscous. The viscosity of fresh latex with a total solid content of about 35% is about 12-15mpa·s, which varies greatly with the collection time and other factors.

Generally, the viscosity of latex with high total solid content is high, but the viscosity of latex with the same total solid content will be relatively different due to different storage methods, storage time and particle size.

Value. The pH value of latex has a great influence on its stability. Fresh latex is neutral and slightly alkaline with a pH of 7. After a few hours to a dozen hours, due to the influence of bacteria and enzymes in the latex, the pH level decreases and becomes acidic, leading to coagulation.

For this purpose, ammonia or other alkalis are often added to raise the pH value to 10 for long-term storage.

The biggest difference between latex and rubber is that one is liquid and the other is solid. After the natural latex is cut from the rubber tree, if it is not refined or sealed immediately, it will all dry up and harden, and the rubber after drying is rubber. If it becomes rubber, it will not have the function of latex antibacterial and anti-mite.

First of all, the nature is different. Latex is a milky white liquid that belongs to biosynthetic products. Rubber is a natural polymer compound, and its main component is polyisoprene.

Rubber paint is also known as leather paint. Sprayed on the surface of the object, it is matte or semi-matte, the feel is quite delicate and smooth, and the appearance is elegant and solemn. Excellent scratch resistance, weather resistance, and abrasion resistance.

In line with green and environmentally friendly printing, there is no damage to the human body. Excellent workability and good adhesion. And it can cover up the defects or water lines that appear in general injection molding.

Rubber paints can be used on ABS, PVC plastics, as well as products and metal surfaces sprayed with special primers. Such as: hair dryer, mobile **, computer mouse, game console, pen, microphone, vanity case, telescope, etc. Due to the strong solvency of SO elastic paint, it cannot be sprayed on the surface of any plastic shell sprayed with other spray paint.

Application fields of elastic rubber paint: sports equipment products, telescopes, communication products, high-quality machines, audio-visual products, daily necessities, mobile phone shells, decorations, decorative boxes, leisure entertainment products, game console handles, car interior decoration, microphones, craft gifts, beauty equipment, makeup brush handles, household appliances, hair dryers, sports equipment, computer peripherals, cameras, mice, keyboards, electrical product shells, etc. It is suitable for surface spraying of various plastics, electronics, metals, wood, etc.

Latex paint, also known as synthetic resin emulsion coating, is a kind of organic coating, which is a kind of water-based coating prepared by adding pigments, fillers and various additives to synthetic resin emulsion as the base material. According to the different production raw materials, latex paint mainly includes polyvinyl acetate latex paint, ethylene propylene latex paint, pure acrylic latex paint, styrene acrylic latex paint and other varieties; According to the different environments of the product, it is divided into two types: interior wall latex paint and exterior wall latex paint; According to the glossy effect of the decoration, it can be divided into matte, matte, semi-glossy, mercerized and glossy types. Coatings are divided into three categories: inorganic coatings, organic coatings and organic and inorganic composite coatings.

Among them, organic coatings are divided into three types: solvent-based, water-soluble and latex coatings: paint is a common name for oil-based coatings, with organic solvents as the dispersion medium; Water-based coatings use water as the dispersion medium. According to the different dispersion methods, water-based coatings can be divided into two types: water-soluble and water-dispersible.

Latex paint is a water-dispersible coating, which is made of synthetic resin emulsion as the base material, and the filler is refined by adding various additives after grinding and dispersion. According to the characteristics and scope of application, latex paint is divided into interior wall latex paint, exterior wall latex paint, other special paints, etc. If you want to do wall paint, of course, it's the latter!

The main difference between natural latex and natural rubber is that natural latex is highly elastic and not easy to deform, durable and resistant to breakage, and is generally used in medical and fitness equipment, while natural rubber is mainly used in the tire industry.

Natural rubber latex is a thermoplastic synthetic resin of the rubber class, which is characterized by high elasticity, good film-forming performance during bonding, and flexible film, so that the adhesive film has excellent flexural resistance, shock resistance and creep resistance, and is suitable for the bonding of parts under dynamic conditions and the bonding between materials with different thermal expansion coefficients.

Natural rubber is a natural polymer compound with polyisoprene as the main component, the molecular formula is (C5H8)N, 91% of its composition is rubber hydrocarbons (polyisoprene), and the rest is protein, fatty acids, ash, sugars and other non-rubber substances. Natural rubber is the most widely used general-purpose rubber.

Characteristics of natural latex, taking latex tubes as an example:

1. Ultra-high elasticity.

2. Orthopedic function.

3. Super breathability.

4. Durable and not easy to deform.

5. Anti-mildew and antibacterial.

6. Ultra-quiet, no static electricity and radiation.

Natural rubber, on the other hand, does not have these properties as a synthetic.

Silica gel (silica gel; Silica) alias: silicate gel is a highly active adsorption material, which is an amorphous substance, and its chemical formula is MSIO2·NH2O; It does not react with any substance except strong alkali and hydrofluoric acid, is insoluble in water and any solvent, is non-toxic and tasteless, and has stable chemical properties. Various types of silica gel form different microporous structures due to their different manufacturing methods.

The chemical composition and physical structure of silica gel determine that it has the characteristics that many other similar materials are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. Silica gel is divided into the following according to the size of its pore size:

Macroporous silicone, coarse-pore silicone, B-type silicone, fine-porous silicone, etc.

Latex generally refers to a colloidal emulsion formed by polymer particles dispersed in water. Also known as latex. It is customary to refer to the aqueous dispersion of rubber particles as latex, and the aqueous dispersion of resin particles as emulsions.

Products made of latex as raw materials are called latex products, such as sponges, gloves, toys, hoses, etc.

Nowadays, there are many silicone products and latex products in life, and as a common one, silicone pillows and latex pillows should be silicone pillows, and many parents also prefer to buy pillows made of these two materials for their children, because silicone and latex pillows are relatively soft and comfortable. However, there are certain differences between these two materials, so let's understand the difference between silicone and latex.

First of all, silicone is better than latex in quality, because silicone is more durable than latex and is not easy to deform, so many parents prefer to buy silicone pillows. Moreover, when denitrite treatment, latex is not certain, so when the human body comes into contact with latex, it is more likely to produce allergic reactions than silica gel. In addition, the adsorption performance of silica gel is relatively high, and the thermal stability is good, the chemical properties are stable, and the mechanical strength is relatively high, but the latex is slightly worse in this regard.

Take our more common baby pacifier modification source to make a comparison, maybe everyone will be more clear about the difference between the two. The nipple made of silicone is generally food grade, which is truly safe and transparent, non-toxic and tasteless, and has no effect on children, and the low temperature can reach minus 40 degrees Celsius and the high temperature can reach 280 degrees. However, latex pacifiers are different, such as rubber pacifiers are relatively easy to deform, and the anti-aging rot collapse performance is relatively weak, the heat resistance is also relatively poor, and it will even exude a kind of rubber taste at high temperatures.

First, the nature is different:

1. Latex is a milky white flowing liquid that looks like milk. Latex is a biosynthetic product whose composition and colloidal structure vary greatly due to differences in tree species, geology, climate, and other relevant conditions.

2. Rubber is a natural polymer compound with polyisoprene as the main component. The composition of its 91 94 is rubber hydrocarbons and the rest is proteins. Natural rubber is the most widely used general-purpose rubber.

Second, the products are different.

1. Common latex products: sponges, gloves, pacifiers, hoses, etc.

2. Common rubber products: tires, basketballs, table tennis rackets, etc.

Third, the constituent substances are different.

1. Natural latex, due to the different tree species, geology, climate and other related conditions, its composition and colloidal structure will often appear huge differences. In fresh latex without any substance, rubber hydrocarbons account for only 20%-40% of the total, and the rest are a small amount of non-rubber components and water.

The non-rubber components include proteins, lipids, sugars and inorganic substances, some of which form a composite structure with rubber particles, and some of which are dissolved in whey or form non-rubber particles.

2. Natural rubber is made of latex, and some of the non-rubber components contained in latex remain in the solid natural rubber. Generally, natural rubber contains 92%-95% of rubber hydrocarbons, while non-rubber hydrocarbons account for 5%-8%. Due to different manufacturing methods, different origins and even different rubber picking seasons, the proportion of these ingredients may be different, but basically within the range.

Protein can promote the vulcanization of rubber and delay aging. On the other hand, protein has strong water absorption, which can cause moisture absorption and mildew of rubber, decreased insulation, and protein also has the disadvantage of increasing thermogenesis.

Acetone extract is a number of high-grade fatty acids and sterols, some of which act as natural antioxidants and accelerators, and some can help the powdered compounding agent disperse and soften the raw rubber during the mixing process.

The ash mainly contains salts such as magnesium phosphate and calcium phosphate, and there are very small amounts of metal compounds such as copper, manganese, iron, etc., because these valence metal ions can promote the aging of rubber, so their content should be controlled.

The moisture in the dry rubber does not exceed 1%, and it can be volatilized during processing, but when the moisture content is too much, it will not only make the raw rubber easy to mold during storage, but also affect the processing of rubber, such as the compounding agent is easy to agglomerate during mixing; It is easy to produce bubbles in the process of calendering and extrusion, and bubbles or sponges are produced in the process of vulcanization.

Latex and rubber are two material names that people often hear, so is latex the same as rubber? Let's talk about the difference between latex and rubber?
