High pressure steel wire braided hose inner plastic depending on the nature of the media to meet the pressure and temperature range may be, in addition to the commonly used NBR (nitrile rubber), but taking into account the requirements of lower permeability, used IIR (butyl rubber), FKM ( fluorine rubber), HNBR (hydrogenated nitrile rubber), modified nylon. To reduce costs, the outer coating of the inner thin layer of rubber or a modified nylon layer FKM. High pressure steel wire braided hose in rubber layer selectable low acrylonitrile content of nitrile rubber or neoprene. By adding to the SBR rubber compound or CR, can improve the copper wire with NBR rubber adhesive properties. High pressure steel wire braided hose outer layer prior to CR (chloroprene rubber) based, has been widely used EPDM (ethylene propylene diene monomer), IIR (butyl rubber), NBR (nitrile rubber) and CSM (methyl chloride polyethylene) or chlorinated polyethylene or ECO (epichlorohydrin rubber) and used to improve weather resistance, ozone resistance and low temperature performance. http://www.rqjiaoguan.com/
