TT (polytrimethylene terephthalate) is a thermoplastic that can be spun into both fibers and yarns. PTT belongs to a class called aromatic polyesters. In both carpet and textile markets, PTT combines the chemical resistance characteristics that you can get from a polyester with the elastic recovery and resilience of nylon. PTT also offers inherent stain resistance, is continuously printable and dyeable without speciality chemicals in a full colour range. Furthermore, PTT has a good colour fastness against UV light, ozone and NOx. PTT provides lower water absoroption and has the potential to be recycled. Many of these same properties make CORTERRA Polymers good candidates for conversion into film, non-woven fabric and monofilament. For engineering thermoplastic applications, CORTERRA Polymers can be compounded to provide performance properties and processing characteristics that are similar to polybutylene terephthalate (PBT).
