The temperature resistance range of natural rubber, under normal circumstances, the lowest temperature that rubber can withstand is about minus 200 degrees, and the highest temperature that can be tolerated is about 300 degrees.

Sealing rings are primarily used to seal gases against oil, water, and corrosion, preventing leakage. The functions of various sealing rings are as follows: O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, they are limited to low-speed rotary sealing devices. V-rings are generally installed in rectangular grooves on the outer or inner circumference for sealing. V-rings are axially acting elastic rubber seals used for pressureless sealing of rotating shafts.

Natural rubber has a series of excellent physical and mechanical properties and is the rubber with the best comprehensive properties. Natural rubber has both advantages and disadvantages

The processed products with Silicone as the main raw material are collectively referred to as Silicone products. Silicone material can be divided into ordinary grade, food grade, medical grade and special Silicone.

The polarity of nitrile rubber is very strong, and the compatibility with other polymers is generally not very good, but it is compatible with chloroprene rubber, modified phenolic resin, polyvinyl chloride and other polar polymers, especially with chlorine-containing polymers.

Nitrile-butadiene rubber (NBR) is a copolymer of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and viscosity Relay is strong.

EPDM rubber is a terpolymer of ethylene, propylene, and non-conjugated dienes, and commercial production began in 1963.
