What s the difference between PU and PVC? Which is better in terms of anti slip effect

PU is better than PVC in terms of non-slip effect (used on wet floors), softness, and comfort

Most people will refer to synthetic leather other than genuine leather, such as PVC and PU leather, as artificial leather or imitation leather. PVC and PU are both polyvinyl chloride (a type of plastic), but the manufacturing process of these two products is different.

In the manufacturing process of PVC leather, the plastic particles should be hot-melted and stirred into a paste, evenly coated on the base of the T C knitted fabric according to the specified thickness, and then foamed in the foaming furnace, so that it has the softness that can adapt to the production of various products and different requirements, and the surface treatment is carried out at the same time as the furnace (dyeing, embossing, polishing, matting, grinding surface fluffing, etc., mainly in accordance with the specific product requirements).

PU leather is more complex than PVC leather in the manufacturing process, because the base fabric of PU is a canvas PU material with good tensile strength, in addition to being coated on the top of the base fabric, the base cloth can also be contained in the middle, so that the existence of the bottom cloth is not the same. The physical properties of PU leather are better than PVC leather, with bending resistance, good softness, high tensile strength, and air permeability (PVC none). The pattern of PVC leather is made by hot pressing of steel pattern rollers; The pattern of PU leather is to use a kind of pattern paper to heat press on the surface of semi-finished leather, wait for it to cool down, and then separate the paper leather for surface treatment.

The ** of PU leather is more than twice as high as that of PVC leather, and the ** of PU leather with some special requirements is 2-3 times higher than that of PVC leather. Generally, the patterned paper required for PU leather can only be scrapped after 4-5 times; The service life of the pattern roller is long, so the cost of PU leather is higher than that of PVC leather.

There are also certain differences in the scope of application of these two materials. In terms of footwear, PVC leather is mostly used in lining or non-weight-bearing parts, or in the manufacture of children's shoes; PU leather can be applied to the fabric of footwear or to the parts that bear weight. In terms of bags, PVC leather is more applicable.

This is because the items in the bag are different from the feet worn in shoes and do not emit heat; You don't have to bear your personal weight.

The difference between PU and PVC is relatively easy, and the base fabric of PU is much thicker than PVC from the corners, and there is also a difference in the feel, and the feel of PU is softer; PVC has a harder feel; It can also be burned with fire, and the taste of PU is much lighter than that of PVC. The advantages of PVC gusset are mainly as follows:

1.Light weight, heat insulation, heat preservation, moisture-proof, flame retardant, acid and alkali resistance, corrosion resistance.

2.Stability, good dielectric, durable, anti-aging, easy to weld and bond.

3.Strong flexural strength and impact toughness, high elongation at rupture.

4.It is easy to process and form through kneading, mixing, pulling tabs, pelletizing, extrusion or die-casting, and can meet the needs of various profile specifications.

5.The surface is smooth, the color is bright, it is highly decorative, and the decorative application is wide.

6.The construction process is simple and the installation is more convenient.

PU is a colloid, a bit like glue, and PU is also a polyurethane. It's like plastic, it has a leather feeling, and it can be made into fake leather clothes.

The PU material is good, and the specific differences between the two are as follows:

1. The ability to withstand high temperature is different

Under normal circumstances, the maximum temperature that PVC material can withstand is only 65 degrees Celsius, while the maximum temperature that PU material can withstand can reach 90 degrees Celsius, so in comparison, the high temperature resistance of PU material will be better.

2. The wear resistance is different

In the same environment, compared with the PU material, the wear resistance of the PVC material will be better, and in the process of use, it is not easy to crack and has a longer service life.

3. The hardness is different

In the same way, if the PVC material and the PU material are processed into steel wire hoses, then the PVC steel wire hose will be harder, while the PU steel wire hose will be relatively soft. However, in order to ensure the practicability of the pipe, some businesses will add plasticizers to the missing materials in the production process, so that the steel wire hose made of PVC material becomes softer, but the environmental protection will be lower.

4. The scope of application is different

PU material is generally used to transport liquids, with a wide range of applications, including agriculture, medical industry, garden, food and other industries, while PVC material can be used to transmit liquids, mortar materials, gases, etc., most of which are used in electric power industries, municipal engineering and other industries.

5. **Different

Although PVC material will be excellent in tensile and compressive resistance, but because of the poor environmental performance and not suitable for use in low temperature environments, so in the same case, the price of PU material products will be higher, of course, PU material wear resistance, corrosion resistance and other aspects will be more excellent.

Kiss is happy to answer for you: PU or PVC material which is good Answer: kiss PU leather is better PVC, PU are polyvinyl chloride (a kind of plastic):

In terms of packages. They are PU artificial leather and PVC artificial leather, the quality of PU artificial leather is good or bad, and good PU artificial leather is even more expensive than genuine leather. The composition of PVC artificial leather is much more complex, and many components have an impact on the human body.

In addition to the cloth stuff, most of the bags are made of PVC leather. Durable', affordable. If you want to buy a bag made of good PVC leather, the quality will be fine.

Of course, high-end PU leather bags are also good, especially wet ones. Personally, I think PU is better, the physical properties of things made by PU are better than PVC, PU is more resistant to twists and turns, and the softness is better, the tensile strength is high, and the air permeability is also better.

PVC (polyvinyl chloride) and PU (polyurethane) are two different plastic materials, each of which has its own advantages and disadvantages, and the specific choice of material depends on the application scenario and needs.

PVC is a commonly used plastic material, which has a wide range of applications in underground drainage pipes, wire and cable protective covers, clothing, shoes and other fields. The advantage is that the texture is flexible, can be processed into a variety of shapes, the cost is low, and the chemical resistance is good, and the durability is strong. The disadvantage is that it is easy to become brittle, and it is easy to age and crack when exposed to ultraviolet rays for a long time.

PU is a polymer material with excellent properties, which can be used to make elastomers, rigid foams, coatings, etc. The advantages of PU are good elasticity, wear resistance, aging resistance, and good waterproof and moisture-proof performance. The disadvantage is that the cost is relatively high, and at the same time it is flammable, so it needs to be well protected from fire.

To sum up, PVC and PU have their own advantages and disadvantages, and which material to choose should be considered comprehensively according to the specific application situation and needs. If you need a flexible material with good chemical corrosion performance, you can choose PVC; If you need good elasticity, waterproof and moisture-proof, and certain wear resistance, you can choose PU.

Summary. PU material has the characteristics of softness, wear-resistance, breathability, etc., and is often used to make shoes, leather clothing, gloves, etc. Therefore, if you need a waterproof and corrosion-resistant material, you can choose PVC material; If you need a soft, breathable material, you can choose PU material.

In addition, it should be noted that PVC material is easy to release harmful substances in a high-temperature environment, which has a certain impact on human health, while PU material is relatively safe. Therefore, if you need to use it in a high-temperature environment, it is recommended to choose PU material. In addition, the ** of PU material is relatively high, but its durability and comfort are also relatively better.

PVC material is relatively cheap, but the life and comfort are slightly inferior to PU material. Therefore, it is necessary to consider various factors when choosing a material. In short, PVC and PU materials have their own advantages and disadvantages, and the specific choice should be decided according to actual needs.
