摘要:
The manufacture of flat molded members or films that have anisotropic thermal expansion coefficients is done from extrudable thermoplastic polymer molding materials by filling the thermoplastic polymer molding materials with lamellar layered silicates that have a diameter in the range of 10 to 1000 nm and an aspect ratio from 1 to 5 to 1 to 10000, extruding the filled thermoplastic polymer molding materials and subsequently uniaxially or biaxially stretching the extrudate into flat molded members or films.
