Process for embossing polymeric substrates by using a composite structure of an aromatic polyamide fabric coated with a fluorosilicone rubber |
摘要 |
A process for embossing flexible polymeric substrates in a dielectric heating press having a platen and a design fixture by placing an insulating blanket of a composite sheet structure between the substrate being embossed and the platen of the press and embossing the substrate; wherein the composite sheet structure is an aromatic polyamide fabric coated on both sides with a 2-30 mil thick layer of a fluorosilicone rubber and having a dielectric constant of about 4-8 and a dissipation factor of about 0.015-0.030; the polymeric substrates generally are laminates of thermoplastic polyurethane form/short napped synthetic velour fabric used as upholstery for automobiles and trucks.
