1. Fluororubber: Possesses high-temperature resistance, can be used in environments ranging from -30°C to +250°C, and is resistant to strong oxidizers, oils, acids, and alkalis. It is commonly used in high-temperature, high-vacuum, and high-pressure environments. Due to its various excellent properties, fluororubber is widely used in petroleum, chemical, aviation, aerospace, and other sectors.

2. Silicone Rubber: Features outstanding resistance to high and low temperatures, maintaining good elasticity in the temperature range of -70°C to +260°C. It also offers advantages such as ozone resistance and weather aging resistance, making it suitable for sealing gaskets in thermal machinery. As it is non-toxic, it can be used to produce thermal insulation, insulating products, and medical rubber products.

3. Nitrile Rubber: Exhibits good resistance to oils and aromatic solvents but is not resistant to ketones, esters, chlorinated hydrocarbons, and other media. Therefore, nitrile rubber is primarily used for oil-resistant sealing products.

4. Chloroprene Rubber: Offers good resistance to oils, solvents, and chemical media but is not resistant to highly aromatic oils. Its characteristics include excellent weather aging and ozone aging resistance. In production, chloroprene rubber is often used for door and window sealing strips, diaphragms, and general vacuum sealing products.
