High Electrical Insulation ISO FKM Rubber Material FKM
High Electrical Insulation FEPM Aflas Uncured Fluoroelastomer O Ring Oil Seal Compound Material
Characteristics: high alkali resistance, high electrical insulation, more than the general fluororubber FKM conventional performance. Its main used in wire insulation sheath, oil field packer and automobile oil seal. Aflas also has better thermal stability than fluororubber.
Heat resistance: lasts at 200 ° C and is also highly resistant to heat at 250 ° C.
Chemical resistance medium: Excellent chemical resistance for high temperature and high concentration acid and alkali, and have the advantages that FKM does not have, such as sulfuric acid, nitric acid, hydrogen chloride, hydrofluoric acid, etc.
Oil resistance: not only excellent oil resistance, but also excellent amine resistance. A large number of amine additives are added to various lubricants in automobiles such as engine and gear oils. Aflas also has excellent oil resistance to these lubricants.
Processing method: suitable for extrusion, compression forming, injection forming, calendering and other forming methods.
End product: O ring, oil seal, packer, cable, hose, sheet, diaphragm etc.
Application: widely used in automotive, petroleum, textile, chemical and other industry.
End products: sheet, gasket, rubber hose, roller, O-ring, diaphragm, valve sheet, wire, bottle stopper and other products, widely used in automotive, petroleum, textile, chemical and food industry
