What Are The Characteristics Of PVC Soft Rubber And Silicone What Is The Difference ?

Soft rubber is a material that is injection-molded with plastic. It does not need to be vulcanized and soft at normal temperatures. It is called soft. So, pvc soft What features does it have? Pvc soft silicone and what difference does it make? Next, small series to introduce knowledge about these aspects in detail, together and see below.

What are the characteristics of pvc soft rubber

1. Temperature resistance characteristics

In the high-temperature radiation, pvc soft rubber will not break and decomposition, because pvc soft rubber is a silicone product, at the same time, it is also low temperature resistance, so that it can be used in a very wide range.

2. Weather resistance

If you have a certain understanding of silicon, then it will know that silicon is not easily decomposed by ultraviolet light and ozone, so that the stability of pvc soft materials becomes very good, and the weatherability is strong. It is used in natural environments. Life is very long.

3. Electrical insulation performance

Has good electrical insulation properties, and all insulating material coefficients are among the best, such as electrical loss, voltage resistance, arc resistance, corona resistance, volume resistance, etc., and these electrical properties are affected by temperature and frequency is very small. Therefore, pvc soft rubber is widely used in electronics and electrical industries.

4. physiological inertia

Polysiloxanes are one of the most inactive compounds known. They are very resistant to biological aging, have no rejection reaction with animals, and have good anticoagulant properties.

5. Low surface tension and low surface energy

The main chain of silicone is very supple, its intermolecular force is much weaker than hydrocarbon, so the surface tension is weak, the surface energy is small, and the film forming ability is strong. This low surface tension and low surface energy are the main reasons for its many applications: hydrophobicity, defoaming, foam stabilization, anti-sticking, lubrication, glossing, and other excellent properties.

What is the difference between pvc soft rubber and silicone?

1. The product of PVC is made of polyvinyl chloride and oil, together with color paste, and its raw materials are made by cooling with a micro-ejection and dispensing process. In the case of silica gel, the chemical elements are pressed and compounded by using a silica gel and a masterbatch paste. After being placed in a mold, they are heated and cooled by a hydraulic press.

2. From the outside, PVC products are relatively rough compared to silicone products, silicone products, the surface is smooth, with color.

3. According to the judgment of the hand, the silicone product is soft, the toughness and elasticity are better, the pvc soft rubber is relatively less hard, and both of the softness can be adjusted, but the PVC has no toughness.

4. PVC materials are common materials and environmental protection materials also called ATBC-PVC, and silicone can be ROHS certified, is environmentally friendly.

5. Silicone products are generally made to be relatively transparent, burning odor is relatively small, the product into a powder, and PVC products will be black after burning the fire, the smell of burning unpleasant.

6. Silicone products are more resistant to heat and cold in PVC products. Silicone products can be heated in a microwave oven, but PVC is not acceptable.

Article Summary: Features about the pvc soft and soft pvc and silicone differentiated knowledge, above small series have been introduced over, available to every interested friends need to know or learning and reference, I hope this can be for everyone Offer to help.
