Product Description

O-ring

Fkm ring is a kind of high performance sealing material, which is widely used in various mechanical equipment and plays a key sealing role. Its unique fluorine rubber material gives it excellent high temperature resistance, acid and alkali resistance, corrosion resistance and other characteristics. The main fluorine rubber ring in the store, the maximum working pressure difference can reach a high standard, the filtration precision is fine, and the glass fiber filter layer is used, especially suitable for the sealing of fuel and other media.

Classification and Uses

1.classification

O-rings are classified in various ways. Among them, fluororubber O-rings are widely used due to their properties such as heat resistance, cold resistance, aging resistance, insulation and corrosion resistance. The NOK sealing rings provided in the store are a type of imported O-rings, specially designed for sealing components of chemical equipment, machinery, electronic machines, etc. The operating temperature range is -40 to 260℃.

2.use

O-rings are the most commonly used sealing components in hydraulic and pneumatic systems and are widely applied in the ‌ automotive industry ‌ to seal oil, gas and liquid in engines, gearboxes, fuel systems, braking systems and air conditioning systems. Youdaoplaceholder0 general machinery ‌ hydraulic components for machine tools, construction machinery, agricultural machinery and other equipment. Youdaoplaceholder0 high-end manufacturing ‌ precision sealing in fields such as aerospace (sealing hydraulic oil, fuel), semiconductor equipment, petrochemicals, etc. ‌ ‌

Detailed introduction

Fluorine rubber O-rings are sealed based on the principle that they generate a return force through deformation caused by external force. The quality of rubber elasticity and tensile strength is one of the very important indicators for evaluating the quality of sealing rings. The elasticity of rubber is generally expressed by the resilience rate, and sometimes it can also be represented by the elongation rate and deformation. The imported materials have a large elongation rate, small deformation and great elasticity. And its high elasticity is mainly related to its molecular weight, conformational entropy of the coiled molecules, crosslinking density of the vulcanized rubber and the type of crosslinking bonds, etc. A large molecular weight of rubber is conducive to the improvement of its elasticity. Moderate cross-linking can reduce or eliminate the slip between molecular chains, which is conducive to the improvement of elasticity. Moreover, for polysulfide bonds with lower bond energy and less binding force on the movement of molecular chain segments, their resilience is also better.
