The inner wall types of rubber industrial hoses
Oil resistant rubber sheet is an important variety of rubber sheet, according to its different characteristics can be roughly divided into three categories.
Type A oil resistant rubber sheet that is the general oil resistant rubber sheet that is made of regenerated nitrile rubber plus A variety of filler materials vulcanization, the center can be pressed cloth and other fabrics in order to improve the physical and mechanical functions of oil resistant rubber sheet.
The primary characteristics of class A oil resistant rubber sheet are oil resistance and wear resistance, water resistance, shock resistance, anti-slip function is good. Mainly suitable for some mechanical processing, production profession, car and ship industry, chemical enterprises, etc., mainly used for the ground, table foil, oil resistance, waterproof, anti-slip effect, avoid direct touch with the ground to form product damage, and maintain the ground or table because of heavy objects knock against the formation of damage.
Type B oil resistant rubber sheet is made from 30 % ~60 % nitrile rubber plus styrene butadiene rubber and filler vulcanization, moderate price. Type B oil resistant rubber sheet has good physical and mechanical function and medium oil resistance. It has the advantages of tightness, wear resistance, bending resistance and low shrinkage deformation rate. Can be used in oil medium (oil, hydraulic oil, lubricating oil, vegetable oil) as a seal. Mainly suitable for gasket processing, equipment fabric, sandblasting fabric and other enterprises processing supporting, insulating rubber sheet and touch oil class, the workbench, ground, electronic product places with high wear resistance requirements for a long-term use of foil, class C oil resistant rubber sheet is made of more than 70 percent of nitrile rubber plus filler vulcanization.
Type C oil resistant rubber sheet excellent oil resistance, high temperature resistance, can be used in 120 degrees high temperature oil medium (oil, diesel oil, gasoline, lubricating oil). Because oil resistant seal standard parts are directly produced by seal manufacturers, as long as some non-standard large seals can be used on class C oil resistant rubber sheet, so class C oil resistant rubber sheet is used in a narrow range and the price is more expensive. Mainly used for punching some high oil resistant gaskets, as oil tank, oil pipeline sealing application.
