In fact, ordinary silicone rubber raw materials contain precipitated substances, and his color will appear translucent or milky white. What are the three major properties of silicone rubber products? So today Plastic Balls Manufacturer is here to provide you with the details about the three major properties of silicone rubber products!
1. High temperature resistance
The most notable characteristic of silicone rubber is high temperature stability, which can be used for a long time in the environment of 250-300 degrees. If the appropriate silicone rubber filler and silicone rubber high-temperature additives are selected, the use temperature can be as high as 375 degrees, and can withstand thousands of degrees of high temperature in an instant. It is estimated that silicone rubber has a service life of up to 20 years at 120 degrees and 5 years at 150 degrees, making it difficult to age.
2. Low temperature elasticity
Silicone rubber products have inherent low-temperature elasticity. Silicone rubber products or other synthetic rubbers have a low embrittlement point. Silicone rubbers can normally work at low temperatures of -50 degrees to -60 degrees.
Silicone rubber film has good breathability. The air permeability of air, nitrogen, oxygen, carbon dioxide and other gases at room temperature is 30-50 times higher than that of natural rubber.
