O-type rubber strip is a commonly used sealing material, and its cross-section shape is circular, so it is named "O-type". O-strips are made of soft materials, usually including silicone and rubber two common materials.
Silicone Rubber: Silicone rubber is a synthetic elastic material with excellent high temperature resistance, aging resistance and deformation resistance. It has the following characteristics:
High temperature resistance: Silica gel can maintain the elasticity and sealing properties of the material over a wide temperature range and can be used for high temperature applications.
Chemical resistance: Silica gel has good corrosion resistance to acids, alkalis, solvents and many chemical substances.
Oxidation resistance: Silica gel has excellent weather resistance and oxidation resistance in oxygen environment.
Insulating properties: Silica gel is an excellent insulating material used in electronic equipment and electrical fields.
Flexible and durable: silicone has good flexibility and durability, and can adapt to a variety of deformation and extrusion.
Rubber: Rubber is an elastic material, often used to make O-shaped rubber strips. Common Rubber materials include Nitrile Rubber, Ethylene Propylene Diene Monomer (EPDM), and Chloroprene Rubber. The characteristics of rubber material are as follows:
Wear resistance: Rubber has good wear resistance and performs well in mechanical seals.
Elasticity and softness: Rubber has good elasticity and softness and can adapt to different shapes of joint parts.
Chemical resistance: Rubber has good corrosion resistance to many chemical substances.
Sealing performance: Rubber material can provide good sealing performance to prevent leakage of liquid, gas or dust.
Whether it is silicone or rubber material, O-type rubber strips are widely used in sealing, waterproof, sound insulation, shock absorption and dust prevention in industrial, construction, automotive, electronic equipment and other fields. When selecting the specific material, it is necessary to evaluate and select according to the application environment, working temperature, chemical exposure and other factors.
