摘要： A tetrafluoroethylene based resin molding material excellent in high frequency electric characteristics which provides a formed product having a relative dielectric constant of 2.2 or less and a dielectric loss tangent of 1.60 x 10-4 or less at 12 GHz and a standard specific gravity of 2.192 or more and less than 2.3. AS the tetrafluoroethylene based resin, use is preferably made of a homopolymer of terafluoroethylene or a copolymer of 99.9 to 99.9999 mole % of terafluoroethylene and 0.0001 to 0.1 mole % of a specific fluoromonomer. The tetrafluoroethylene based resin molding material has good electric characteristics particularly a low dielectric loss tangent also in a microwave region, can be extruded by a reduced extrusion pressure due to its low molecular weight and can provide a formed product excellent in smoothness of its surface, and thus is useful as a material for use in the equipment using a microwave such as a device for satellite communication, a portable telephone base station and the like, for example, as a coating material for a coaxial cable.

摘要： A fluoroelastomer having good heat and oil resistances and excellent extrudability and mechanical properties. It is composed of vinylidene fluoride units, hexafluoropropylene units and, occasionally, at most 35 wt.% of tetrafluoroethylene units, contains bound iodine, and has a multi-peak molecular weight distribution. It can be sufficiently vulcanized in the wide range from the low-molecular-weight to the high-molecular-weight components thereof to give a high-strength vulcanizate having a good balance between elongation and strength, and can be improved in compression set because it can be increased in cross-linking density.

摘要： The fluorine-containing elastomer of this invention has a composition comprising vinylidene fluoride units and hexafluoropropylene units in a designated ratio, optionally, not more than a designated amount of tetrafluoroethylene units, and bound iodine, and has a multi-peak type molecular weight distribution and a designated inherent viscosity number, where the ratio of the amount of a low molecular weight polymer to the inherent viscosity number and the ratio of the weight-average molecular weight to number-average molecular weight are within specified ranges. When said elastomer is vulcanized, its bound iodine at a terminal thereof is eliminated and the polymer links through its terminal groups via an unsaturated compounded and is cross-linked between polymer chains by a curative thereby thoroughly being cured including a low molecular weight component to a high molecular weight component, resulting in a high strength vulcanizate which also has an excellent balance in strength and elongation; the vulcanizate, because of an improved cross-linked density, gives improved compression set as well as improved solvent resistance and chemical resistance; and it can be made into an elastomer compound having excellent processability, excellent vulcanizate properties, freedom from sticking to [mill]-rolls, good work efficiency, and excellent productivity, thereby making this a suitable material in fuel hoses and automotive engine compartment parts.
