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.
摘要:
A fluororubber-containing powder coating composition comprising a fluororubber, an adhesion-preventing material and optionally a cross-linking agent, which composition has an particle size of 10 to 2,000 µm and an apparent density of at least 0.2 g/cc, which provides a homogeneous smooth coated film having no or little bubbles.
摘要:
@ An impregnated material comprising an organic or inorganic material selected from the group consisting of a woven fabric, a non-woven fabric and an open cell porous material which is impregnated with a copolymer which comprises 50 to 95 % by mole of repeating units derived from tetrafluoroethylene and 5 to 50 % by mole of repeating units derived from perfluoroalkyl vinyl ether of the formula: wherein R, is a C 1 -C 6 perfluoroalkyl group or a group of the formula. wherein R, is the same as defined above, X is a fluorine atom or a trifluoromethyl group and n is an integer of 1 to 10, which has good chemical, corrosion, solvent and oil resistance as well as water- and oil-repellence.
