Producto industrial compuesto de relleno de poliuretano termoplástico TPU LGF

Product information

TPU is short for Thermoplastic Urethane, and its Chinese name is thermoplastic elastomer. TPU is a polymer material formed by reaction polymerization of TDI, macromolecular polyols and chain extenders. Its molecular structure is alternately composed of rigid blocks obtained by the reaction of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and chain extender, and flexible chain segments obtained by the reaction of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and macropolyols. TPU has the characteristics of high tension, high tension, toughness and aging resistance, so it is a mature environmental protection material.
At present,TPU has been widely used in medical and health, electronic appliances, industry and sports, etc., it has incomparable high strength, toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, climate resistance and other characteristics of other plastic materials, and it has high water and moisture resistance, wind and cold resistance, antibacterial, mildew resistance, warm, ultraviolet resistance and energy release and many other excellent The function of
Thermosetting plastic TPU features a wide range of hardness: by changing the proportion of each reaction component of TPU, you can get different hardness products, and with the increase of hardness, its products still maintain good elasticity and wear resistance.
High mechanical strength :TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.
Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees Celsius.

Frequently asked questions

1. Does long glass fiber and long carbon fiber injection have special requirements for injection molding machines and molds?

There are certainly requirements. Especially from the product design structure, as well as the injection molding machine screw nozzle and mold structure injection process must consider the requirements of long fiber.

2. Under what circumstances can long fiber replace short fiber? What are the common alternative materials?

Los materiales tradicionales de fibra cortada se pueden reemplazar con fibra de vidrio larga y materiales LFT de fibra de carbono larga en el caso de clientes cuyas propiedades mecánicas no se puedan cumplir o donde se deseen sustitutos metálicos más altos. Por ejemplo, la fibra de vidrio larga de PP a menudo reemplaza a la fibra de vidrio reforzada con nailon, y la fibra de vidrio larga de nailon reemplaza a la serie PPS.
