Polyehylene terephthalate film composition
专利汇可以提供Polyehylene terephthalate film composition专利检索，专利查询，专利分析的服务。并且PURPOSE: The title composition for film having improved ktransparency and slipperiness, obtained by adding inorganic inert particles on which polydimethylsiloxane is adsrobed to a polyester consisting oe ethylene terephthalate.
CONSTITUTION: A) A polyester consisting mainly of ethylene terephalate is dryblended with B) 0.07W1.0 wt.% of inorganic inert particles (e.g., barium sulfate having an average particle diameter of 0.1μ) having a light-scattering parameter value not more than 7.00×10
-4 shown by the formula(n is a refractive index of the inorganic inert particles; d is an average particle diameter μ; P is a density of the particles g/cm
3 ) on which 5W15 wt.% of polydimethylsiloxane havng a degree of polymerization of 80W200 and a viscosity of 100W300 cSt. is adsorbed.
USE: Packaging, gold and silver threads, electrical insulation, condensers, and magnetic tapes.
