RE: What are the chemical formulas for polyester, cotton, and nylon? Lv 4. PET is spun into fibers for permanent-press fabrics, blow-molded into disposable beverage bottles, and extruded into photographic film and magnetic recording tape. Thermoplastic polyurethane (TPU) is a melt-processable thermoplastic elastomer with high durability and flexibility. PET Fibers (Mylar, Dacron, and Terylene) have excellent crease and wear resistance and low moisture absorption, and cloth made from PET exhibts good wrinkle resistance. Attempts were made to enhance the dyeability of polyester fabric by thermal treatment or combined chemical/thermal treatment in hot air or in steam, either slack or under load. Polyethylene terephthalate, commonly referred to as PET or simply polyester, is the common chemical name for the polymer used to make products such as polyester fibers, film, and solid-state (bottle) resin. This reaction, together with the addition of compounds such as saturated di-basic acids and cross-linking monomers, forms the basic process of unsaturated polyester manufacture. The melting point of polyester is 250-300°C. We measure it by categorizing into two way. They when mixed with hardener get activated, as hardener works as a catalyst for chemical reaction called polymerization. 0 0.
