OTP Taiwan top Wall is a professional production of imported star-ring (X-ring), usually made of nitrile star-ring, fluorine rubber star-ring. Imported star-ring (X-ring) Description: star-ring (the star-ring), also known as X-ring, which is formed by the mold cross section is four circular annular sealing lip ring, it On the basis of O-ring performance has been improved and enhanced, it can replace most of the O-ring applications. It is a sealing element can in both directions for sealing purposes. When the trenches installed in various forms of radial or axial pre-compression gives initial sealing capability star-ring, with increasing pressure increases the sealing force. Under pressure, the star-ring cross-sectional shape will transfer pressure evenly to all aspects, it has a good seal. Imported star-ring (X-ring) applications: dynamic sealing applications for sealing reciprocating pistons, rods, plungers. For sealing oscillating, rotating or spiral motion of the shaft or spindle. Static sealing applications: seals Radial stationary parts, such as sleeves, end caps, tube. Seal axially stationary parts, such as flanges, covers and so on. Fluorine rubber star-ring: inside (Fluoro Carbon Rubber) of molecular fluorine rubber, according to the fluorine content (ie monomeric building) and there are various types. Six lines of fluorinated FKM currently the most widely used first by the DuPont Company to "Viton" tradename listed. High temperature resistance than silicone rubber, has excellent chemical resistance, resistance to most oils and solvents (ketones, esters excluded), weather resistance and ozone resistance; cold is relatively poor, the general temperature range of -20 ~ 250 ℃. Specially formulated low temperature resistant to -40 ℃. Advantages: 1. heat to 250 ℃ 2. For most of the oil and solvent have the ability to resist, especially all the acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils
