Soft rubber is a material made through plastic injection molding without the need for vulcanization treatment. It feels soft at normal temperatures, hence the name "soft rubber". So, what are the characteristics of
PVC soft rubber strip and what is the difference between PVC soft rubber and silicone? Next, let's delve into these topics in detail. Let's take a look together.
What are the characteristics of PVC soft rubber strip?
1. Temperature resistance
Under high-temperature radiation, PVC soft rubber does not break or decompose. This is because PVC soft rubber belongs to the silicone category, and it also resists low temperatures, making it widely applicable.
2. Weather resistance
If you have some understanding of silicone, you will know that silicone is not easily decomposed by ultraviolet light and ozone. Therefore, PVC soft rubber material exhibits excellent stability and strong weather resistance, with a very long lifespan when used in natural environments.
3. Electrical insulation performance
It has excellent electrical insulation properties, and all insulation material coefficients are among the best, such as electrical loss, voltage resistance, arc resistance, corona resistance, volume resistance, etc. These electrical properties are minimally affected by temperature and frequency. Therefore, PVC soft rubber is widely used in the electronics and electrical industries.
4. Physiological inertness
Polysiloxane compounds are among the most inert compounds known. They are highly resistant to biological aging, have no rejection reaction with animal bodies, and exhibit good anticoagulant properties.
5. Low surface tension and low surface energy
The main chain of silicone is very flexible, and the intermolecular forces are much weaker than those of hydrocarbons. Therefore, it has low surface tension and small surface energy, with strong film-forming ability. This low surface tension and low surface energy are the main reasons for its diverse applications: hydrophobicity, defoaming, foam stability, anti-adhesion, lubrication, glazing, and other excellent properties
