Thermoplastic fluorine-containing resin composition useful for calendering |
摘要 |
The invention provides a thermoplastic fluorine-containing resin composition intended to be passed between at least two rollers of a calender to be thinned into a sheet or film. This composition includes: 100 parts by weight of a mixture containing 10-90 wt % of a fluorine-containing elastomeric polymer having a glass transition temperature below room temperature and 90-10 wt % of a fluorine-containing crystalline resin having a melting point not higher than 300 DEG C.; and 0.05-2.0 parts by weight of an agent for releasing the composition from the at least two rollers. The composition has a good melt characteristic and a good elasticity for calendering of the composition, and a good releasibility from a calender roller in calendering of the composition.
