ETPU (Engineering Thermoplastic Polyurethane Elastomer), engineering polyurethane elastomer material. It is a unique elastomeric material composed of amorphous and rigid molecular chains, and does not contain any flexible segments in its molecular structure. Therefore, ETPU materials not only have the strength and dimensional stability of amorphous resins, but also have the chemical resistance, fatigue resistance and wear resistance of crystalline resins. ETPU products can replace high-performance materials such as: nylon 11, nylon 12, polysulfone, polyformaldehyde, polyimide, reinforced polyester, etc., suitable for applications that need to withstand strong impact and frequent use, require transparency, dimensional stability and chemical resistance Product with excellent performance. Such as: plastic fasteners, connectors, filter housings, water cups, potentiometers, etc.
Isoplast is an ETPU product trademark registered by the American Dow Corporation in 1983. At the beginning of 2009, this series of products were acquired by the United States Lubrizol Company and merged into its subsidiary. It has been officially promoted and sold in mainland China and other regions. Isoplast series products are available in three specifications: transparent, impact-resistant and long glass fiber reinforced.
