flat rubber ring gasket for led headlight seal                                                                   

We can apply the report for material properties for rubber products flat rubber ring gaskets. We cooperate with SGS for the testing item of FDA,ROHS, etc., which are common used for most of the rubber & plastic products.

Rubber flat gasket is applied to all kinds of mechanical equipments, acting as function of backing, sealing and buffering. It can be manufactured by mould pressing, or made by vulcanization film, mould pressing use hydraulic molding machine and mould to press into shape, incision use gasket cutting machine to cut into shape. For mould pressing, it is material saving but one mould can only produce one kind of gasket; for gasket cutting machine, it can cut gasket with 1500mm range freely, but the use rate of gasket material is low. There has difference between rubber flat gasket and rubber O ring: rubber flat gasket is easy to deform and to compress, but pressure and temperature resistance capacity is worse, it only suitable for place where low pressure and temperature; rubber O ring's sectional form is round, it has self-tight function, sealing property is better than flat gasket and its pressing force is smaller. Main rubber flat gasket products includes natural rubber flat gasket, neoprene rubber flat gasket, nitrile rubber flat gasket, silicone rubber flat gasket, fluororubber gasket and other rubber gaskets. Natural rubber is acid and alkali resistance, using temperature has better no more than 60℃; neoprene rubber is resistant to some acid and alkali, using temperature is 80℃; nitrile rubber is resistant to oil, using temperature is 80℃; fluororubber has well corrosion and temperature resistance property, it can be used in 150℃ medium; silicone rubber owns excellent low and high temperature resistance property, it can maintain excellent elasticity within 160℃, and it's resistance to ozone, weather aging, suitable for used as sealing liner in thermal mechanical, and it also has good properties of waterproof, inflaming retarding, high temperature resistance, electric conduction and so on. Rubber gasket is widely used in medicine, electron, chemical engineering, anti static inflaming retarding and food industries.

Molded Fluorocarbon (VITON FKM) Gaskets

All Seals specializes in the converting of custom molded Viton gaskets and seals. Our custom Viton(FKM) molding capabilities include Compression Molding, Transfer Molding, and Rubber Injection Molding. Fluorocarbon, Viton(FKM) compounds are available from 55 to 90 durometer, Shore A. Viton molded gaskets are generally black, brown, or white in color, however custom color compounding is available upon request. Vitonmolding tolerances are complaint with rubber molding industry standard RMA A2 Precision tolerances.
