It is very good performance of chemic erode resistant, impregnant resistant, ozone resistant, radiation resistant, aging resistant, hydrolyze resistant, and high tensile strength, tear resistant, high impact resistant, high bend strength and low compression set etc. The abrasion resistant is 5 multiple more than pure natural rubber, and the oil resistant is 3-5 multiple more than NBR rubber, and have high elasticity 65% with prominent compression resistant at high temperature. Wider revise hardness range on 85-92shore A, very good viscidity with metal material, it is a new macromolecule material with fast evolutive now. Apply to all kinds of hydraulic seal, ring and gasket on military, mine, oil field, chemical, printing, punch, paper making, spin, auto industrial for oil, air and water with better tensile strength, lower compressive deformation, resistant hot and cold temperature,
