Application of TPO Thermoplastic Elastomer

TPO is a new type of automotive interior material.The full name of the product is Thermoplastic polyolefin.

It is just starting to develop in China. Compared with PVC materials, it has the advantages of low density, energy saving and environmental protection.

Polyolefin thermoplastic elastomer is a high-performance polyolefin product that is rubber-elastic at room temperature and has the characteristics of low density, large bending, high low-temperature impact resistance, easy processing, and reusability.Experts predict that this product will be widely used in domestic and foreign automobile manufacturing industries in the 21st century.

The blend of isotactic polypropylene and ethylene-propylene copolymer is called TPO (Thermoplastic Polyolefin) after being combined with fillers, reinforcing agents, antioxidants, pigments, plasticizers and other additives.

TPO extrusion machine has three main application areas: automobiles, wires and cables, and mechanical products.Auto parts are the largest market for TPO. Excellent weather resistance, low density, processing flexibility and low cost make TPO a very common raw material for manufacturing automotive interior and exterior parts, such as air valves, bumper covers, fenders, net windows, rubber strips, ducts, sealing gaskets, and automotive interior decoration parts.

In the field of wires and cables, TPO has replaced PVC and vulcanized rubber in many occasions, such as soft wires, booster cables, instrument wires, and low-voltage sheaths. In addition, there are also special low-smoke and flame-retardant TPO. In the field of wires and cables, the main advantages of TPO are excellent electrical properties, water resistance, and ozone resistance. Nanjing Sumino Seiko professional sheet film coil equipment.

For the convenience of processing, commercially available TPO is a granular product, which can be processed by most thermoplastic processing methods, such as injection molding, extrusion molding, blow molding, vacuum molding, and blown film. The general processing conditions and uses of TPO, as for the specific processing conditions, can be obtained from the supplier.

This product is widely used in automotive accessories. In automotive exterior parts, it is mainly used in bumpers, radiators, chassis, body panels, wheel guards, movable roofs and other protective strips, windshield strips, etc. In interior parts, it is mainly used in instrument panels and interior panel skins, airbag outer skin materials, etc.
