All Kinds of Polyurethane O Ring, PU O Ring, PU Oil Seal, Hydralic Oil Seal
Physical character: Made by injection molding with high quality TPU. 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 60-95shore A, very good viscidity with metal material, it is a new macromolecule material with fast evolutive now. Apply to all kinds of seal, O ring and gasket on military, mine, oil field, chemical, printing, punch, paper making, spin, auto industrial etc.
