In the early stage, many materials in different fields were selected in silicone, rubber and plastic adhesive and HTV adhesive, and in the premise of achieving the requirements of environmental protection and safety level, it must choose high quality silicone sealing ring material, for food grade silicone material, do you know its characteristics and differences?

 

The material composition of food grade O-type silicone ring is mainly polycondensation of silicate inorganic polymer gel material, composition is silicone dioxide, period amount is more than 98%, combined with gas Phase silicone fineness reached 400-1000 mesh, due to the low density has good stability, non-toxic and tasteless, stable chemical performance, food grade silicone sealing ring in addition to hydrogen and fluorine Acid, ozone environmental caustic requirements, and any acid, alkali and salt does not react, it is mainly used in household appliances, household food field surrounding sealing and life cup silicon Rubber ring, pressure cooker sealing ring and other fields,What are the advantages of food grade silicone sealing ring raw material?

Density:1.1-1.12g/cmf

Elongation: about 100% (Judged according to raw materials and hardness and softness)

Color:Translucent, milky white, brilliant, Pantone color can be customized.

Hardness:20° , 30°, 40°, 50°, 60°, 70°, 80°, commonly used in 40°- 70°.

Usage: The most commonly used are silicone gaskets, silicone accessories, silicone seals and other middle and low grade silicone daily accessories.

 

• Good environmental protection and safety effect, non-toxic and tasteless, high transparency.
• Excellent sealing softness, high strength rebound waterproof leakage.
• Good tensile resistance, good rebound effect after long-term use, suitable for different environments.
• Can be heated at high and strong temperature, shape, no harmful substances, the group can be used in high and low temperature environment.
• Long-term use of yellow and colorless, good tensile rebound strength, good softness, high tensile raw materials.
• Corona resistance, arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance, in line with FDA and SGS standards, can pass a variety of testing certification.

 

Silicone rubber products have much better heat resistance than ordinary rubber, can be used almost forever at 150° without performance change, can be used continuously at 200° 10000 Hours, at 350° can also be used for a period of time. Widely used in heat resistant occasions, hot water bottle sealing ring, heat resistant handle of force pot ring.

 

Cold resistance: ordinary rubber is -20° -30°, that is, silicone rubber still has good elasticity when it is 60° -70°, and some special silicone rubber can withstand very low temperature Degree, such as: low temperature silicone O-ring seal.
