Japan's Shin-Etsu Chemical Co., Ltd. is stepping up research and development of high-resilience TPU materials. In automotive applications, the company has developed TPU injection grades for automotive parts, making it possible to use TPU materials for the production of automotive parts, as the company developed TPU materials. Because of its non-adhesive and resilient properties, it has been widely used in sporting goods and toys. The company is working on the production of TPU car parts to meet the demand for new energy vehicles.
In addition, because TPU material has extremely high flame retardancy, it gradually plays an increasingly important role in various industrial applications. The company will also continue to increase investment, and constantly open up the use of TPU materials.
TPU name is thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type, it has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency, good elasticity, in daily necessities, sporting goods, toys , Decorative materials and other fields have been widely used, halogen-free flame retardant TPU can also replace soft PVC, to meet more and more areas of environmental protection requirements.
The so-called elastomer refers to the glass transition temperature is lower than the room temperature, elongation at break> 50%, after the removal of the external force is relatively good polymer material recovery. Polyurethane elastomer is a special class of elastomers, polyurethane elastomer The hardness range is very wide, the performance range is very wide, so the polyurethane elastomer is a kind of polymer material between rubber and plastic.
Its uses mainly include: engineering products, automotive engineering components; fire hoses, soft and hard composite products; gear shift ball handles, rollers, couplings, grommet and seals; cable sheathing, fabric coating, transmission belts, soft Tubes, cable connectors, hose fittings, mine screens, films and extruded profiles; gears, goggle frames, bumpers, sports soles and casters, suspender shoulder straps, straps, etc.
TPU materials under different injection molding conditions: EC-500 and SX-200
