What is the difference between silicone 2670 and 2670pc

The difference between silicone 2670 and 2670ps pc is that this 2670pc is upgraded on the basis of 2670, and the latest product will be a little more powerful.

Flexibility is different.

Second, the molding process is different.

3. Transparency is different.

Fourth, the wear resistance is different.

The difference between the silicone 2670126707 system is that the hardness between them is not the same, and it is used internally.

The difference between the two is that they are the first, and the second is an upgraded version of the first, so it runs better on the system.

There is indeed a difference between the two. Because if they have different models, the content of the ingredients in them may be different.

There is no difference between the two of them, they are basically the same.

There is a difference, mainly in the matter of material.

I'm glad it, there's no problem, the difference here, the former is not a tablet, and the latter is dedicated to tablets.

What is the difference between 192070502070 BC? The difference between them is that the materials are different, although they are all under the same codename, they are not to be discussed.

Differences: First, the flexibility is different.

Second, the molding process is different.

3. Transparency is different.

Fourth, the wear resistance is different.

1. Silica gel: (silica gel; Silica rubber is a highly active adsorption material, which is an amorphous substance, and its chemical formula is MSIO2·NH2O.

Insoluble in water and any solvent, non-toxic and tasteless, chemically stable, does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gel form different microporous structures due to their different manufacturing methods.

2. TPU material.

TPU is the main material for the manufacture of water jacket, is the abbreviation of thermoplastic urethane elastomer, the so-called elastomer refers to the glass transition temperature is lower than the room temperature, the elongation at break is 50%, and the recovery is better after the external force is removed. Polyurethane elastomer is a special category of elastomers, polyurethane elastomers have a wide range of hardness and a wide range of properties, so polyurethane elastomers are a class of polymer materials between rubber and plastics. It can be heated and plasticized, with no or little cross-linking in the chemical structure, and its molecules are basically linear, but there is a certain amount of physical cross-linking.

This type of polyurethane is called TPU

3. PC material.

PC is the abbreviation of polycarbonate, the English of polycarbonate is polycarbonate, referred to as PC engineering plastics, PC material is actually one of the engineering plastics we call a material, as a widely used material in the world, PC has its own characteristics and advantages and disadvantages, PC is an amorphous thermoplastic resin with excellent comprehensive properties, with excellent electrical insulation, elongation, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance; It also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable, etc., and the shadow of PC plastic can be seen in all corners of your life, and the characteristics of large-scale industrial production and easy processing also make it extremely cheap.

The composition properties of PC and silicone are completely different, and even the processing methods are different. In terms of performance, the usable temperature of silica gel is higher than that of PC, but the transparency is worse than that of PC.

PC belongs to plastics, and silicone can replace rubber in some aspects, plastic and rubber are two different fields, and they can't be compared together at all.

See what products you're using for. The two materials are completely different.

There are many kinds of materials in rubber, and silicone is also one of the rubbers, which is divided into ordinary silicone and meteorological silicone according to its performance.

1. Ordinary silica gel (also known as precipitated silica gel).

Elongation: 400%.

Uses: Medium and low-grade silicone products such as mobile phone buttons, miscellaneous parts, and conductive adhesive are used more.

2. Meteorological silica gel (also known as pure silica gel).

Color: Transparent.

Density elongation: 600%-700%.

Features: This material has good transparency, strong tensile strength and high cost.

Uses: Silicone tubes, protective sleeves and other products that require high elasticity.

First, the nature is different.

1. Silicone rubber: It is a rubber whose backbone is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atoms.

2. Silica gel: It is a highly active adsorption material and an amorphous substance.

Second, the characteristics are different.

1. Silicone rubber: Silicone rubber has good low temperature resistance and can generally work at -55; Silicone rubber has good air permeability and the highest oxygen permeability rate among synthetic polymers.

2. Silica gel: Silica gel has a strong adsorption capacity and can have a drying effect on people, so work clothes should be worn during operation. If silicone gets into the eye, rinse with plenty of water and see a doctor as soon as possible**.

Third, the composition is different.

1. Silicone rubber: mainly composed of silicon-oxygen links containing methyl group and a small amount of vinyl. The introduction of phenyl group can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano groups can improve the temperature and oil resistance of silicone rubber.

2. Silica gel: The main component of silica gel is silicon dioxide.

Silica gel according to its nature and.

The components can be divided into:

Silicone. and inorganic silica gel.

Two categories. Inorganic silica gel is a highly reactive adsorption material, which is usually used.

Sodium silicate and. Sulfuric acid reaction, and through a series of post-treatment processes such as aging and acid bubbles. Silica genus.

An amorphous substance with the chemical formula MSIO2

nh2o。Insoluble.

to water and any.

Solvent, non-toxic and odorless, chemical.

Stable, except for strong alkalis

Hydrofluoric acid does not react with any substance. Various models of silicone are formed differently due to their different manufacturing methods.

Microporous structure. Silicone.

Chemical composition. and physical structures.

It is determined that it has many other similar materials that are difficult to replace.

Features: High adsorption performance

Thermal stability. Good, chemically stable, and high.

Mechanical strength. Wait. Silicone is one.

Silicone compounds.

Refers to the presence of Si-C bonds, and at least one of the organic groups is directly related to silicon.

Atomically linked compounds, it is customary to treat those compounds that connect organic groups to silicon atoms through oxygen, sulfur, nitrogen, etc. Among them, the silicon-oxygen bond (-si-o-si-) is.

The backbone of polysiloxane is the most numerous, most deeply studied and most widely used class of organosilicon compounds, accounting for more than 90% of the total dosage.

Silicone rubber is a type of synthetic rubber. It has no smell and is not afraid of toxicity.

High temperature and resistance to severe cold, at 300 degrees Celsius and minus 90 degrees Celsius, "calm", "face does not change color", still does not lose the original strength and.

Elasticity. Silicone rubber also has good.

Electrical insulation. Oxidation resistance, anti-aging resistance, light resistance, aging resistance, and.

Mold resistance, chemical stability.

Wait. Because of these excellent properties, silicone rubber has played an important role in modern medicine. In recent years, hospitals, scientific research institutes and factories have worked together to successfully prototype a variety of silicone rubbers.

Medical supplies.

Taught, thank you, all of you upstairs. I don't know how to test the dehydration ability of inorganic silica gel? It is to absorb enough water and heat it to dehydrate.
