If you let nature have molded nylon macromolecular orientation, crystallinity, try to eliminate the stress of it? That is what we say boiled, boiled with set procedures in fact our metal "tempering" the treatment process has the same purpose. That is to make nylon pieces in a certain temperature soak, let inside macromolecules tend to try to achieve a natural orientation and internal equilibrium crystallization and crystal solution yellow wax cloth, thereby eliminating the internal stresses. Performance on the outside is: nylon pieces greatly enhanced toughness, brittleness basically eliminated. Polyimide is a molecular structure containing imide group links aromatic heterocyclic imide polymer compound hot yellow wax cloth tape, the English name Polyimide (referred to as PI) with a glass cloth with yellow wax cotton cloth, can be divided into pyromellitic type PI , soluble PI, polyamide - imide (PAI) and polyether imide (PEI) four. Yellow wax cloth temperature glass cloth specifications | Xingtai yellow wax cloth | Tianjin Three by Three Plastic Co., Ltd. of Tianjin. Three Plastic Co., Ltd. Tianjin (www.tjzsxszp.com) strong, credible, in Tianjin plastic plate (sheet, section), rods and other industries has accumulated a large number of loyal customers.
