Title:
太陽電池の光電地要素のための白色顔料を含む不透明フルオロポリマー組成物
Document Type and Number:
Japanese Patent JP5783902
Kind Code:
B2
Abstract:
A fluoropolymer composition having a total luminous transmittance (TT) of less than 15%, when measured according to ASTM D1003 on a sample having a thickness of about 50 μm, said composition comprising: at least one hydrogen-containing fluoropolymer [polymer (A)]; from 5 to 80% by weight of (A) of at least one inorganic pigment [pigment (I)]; and from 1 to 99% by weight of (I) of at least one per(halo)fluoropolymer chosen among tetrafluoroethylene (TFE) copolymers having a dynamic viscosity at a shear rate of 1 rad×sec−1 of less than 100 Pa×sec at a temperature of 280° C. [polymer (B)]. By adding polymer (B) to the composition based on polymer (A) it is advantageously possible to obtain an even dispersion of the pigment (I) so that a composition possessing outstanding opacity and still being processable under the form of films, so as to provide adequate mechanical properties, can be manufactured therefrom.
