WebThermoplastic. A thermoplastic is a material, usually a plastic polymer, which becomes more soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemical or mechanical properties. When thermoplastics are heated to their melting point, they melt to a liquid. WebPolytrimethylene Terephthalate (PTT) is a semicrystalline polymer that has many of the same advantages as its polyester cousins, PBT and PET. Compared to PBT, compounds composed of PTT exhibit better tensile strengths, flexural strengths, and stiffness. They also have excellent flow and surface finish. PTT can also be more cost effective than PBT.
