1. Fluororubber: Exhibits high-temperature resistance, operable in environments ranging from -30°C to +250°C, with resistance to strong oxidizers, oils, acids, and alkalis. Commonly used in high-temperature, high-vacuum, and high-pressure conditions. Due to its versatile and favorable properties, fluororubber is widely applied in petroleum, chemical, aviation, and aerospace sectors.

2. Silicone Rubber: Features outstanding resistance to both high and low temperatures, maintaining excellent elasticity in the 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 items.

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

4. Neoprene (Chloroprene Rubber): Offers good resistance to oils, solvents, and chemical media but is not resistant to highly aromatic oils. It is characterized by excellent weather aging and ozone aging resistance. In production, neoprene is often used for door and window sealing strips, diaphragms, and general vacuum sealing products.
