摘要： Fluoropolymer materials containing tetrafluoroethylene monomers, such as PTFE, are significantly swollen by supercritical carbon dioxide at high temperatures and pressures. The swollen fluoropolymer is processable by molding, extrusion, and other techniques. In addition, the fluoropolymer may be sintered at significantly lower temperatures compared to a nonswollen fluoropolymer material. The melting temperature of fluorinated polymers containing tetrafluoroethylene and triflouroethylene monomers which are swollen with supercritical carbon dioxide is significantly reduced, thereby permitting manufacturing operations such as extruding and molding to be performed at lower temperatures and with reduced risk of decomposition.

摘要： A transparent elastomer composition is obtained by co-coagulation of an emulsion of fluorine-containing resin fine particles having an average particle size of from 20 to 150 nm and an emulsion of elastomer particles, in which the fluorine-containing resin fine particles are finely dispersed uniformly in the elastomer. The transparent elastomer composition provides an elastomeric molded article having excellent mechanical strength, abrasion resistance and transparency.
