摘要:
A curable polymer composition comprising 20 to 80 parts by weight of a crosslinkable hydrocarbon elastomer which has a rubber elasticity in the temperature range between -60°C and +230°C, 80 to 20 parts by weight of a vinylidene fluoride base copolymer and 0.5 to 5 parts by weight of a crosslinking agent, which provide, when cured, a packing material having improved chemical and heat resistance.
摘要:
A thermoplastic fluoroelastomer composition comprising a thermoplastic fluoroelastomer, a liquid fluoroelastomer and optionally a cross-linking agent, which is easily ejection molded and cross-linked at a room temperature to afford a cross-linked material having excellent heat resistance, oil resistance and corrosion resistance.
摘要:
A cross-linkable coating composition comprising a fluorine-containing elastomeric copolymer which comprises (a) 50 to 95 % by mole of repeating units derived from a fluoroolefin of the formula: CF₂=CXY (I) wherein X and Y are the same or different and a fluorine atom or a chlorine atom, (b) 50 to 5 % by mole of repeating units derived from a perfluorovinyl ether of the formula: R f -[OCFZCF₂(CF₂) m ] n -OCF=CF₂ (II) wherein R f is a C₁-C₆ perfluoroalkyl group, Z is a fluorine atom or a trifluoromethyl group, n is an integer of 0 to 5 and m is 0 or 1 provided that when m is 1 (one), X is not a trifluoromethyl group and a cross-linking agent for the copolymer, the copolymer and the cross liking agent being dissolved or dispersed in a fluorosolvent is provided.
摘要:
A fluoroelastomer composition comprising a fluoroelastomer, a fluorine-containing surfactant and optionally a vulcanizing agent which has improved processability, particularly mold releasability and mold contamination proofness.
