Thermoplastic vulcanizates. (Materials).


Zeotherm thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene.  vulcanizates (TPVs) are said to be high-performance, heat- and oil-resistant TPVs capable of withstanding temperatures up to 150[degrees]C. This class of thermoplastic elastomers is said to offer the feel and performance of thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic.  rubber with the processing ease, convenience, cycle time and recyclability of a thermoplastic. Due to its capability to withstand the synthetic oils, lubricating fluids and high temperatures present in today's under-the-hood operations in automobile and industrial environments, Zeotherm polymers have potential use in a variety of applications, according to according to

Based on the SAE J200 classification system, Zeotherm is a DH polymer, denoting its excellent heat and oil resistance, according to the company. Zeotherm is said to thrive in long-term, high-heat and oil-resistant surroundings where current silicones, polypropylene-based TPVs and copolyesters fail. (Zeon Chemicals L.P.)
