TPE

what is tpe material?

TPE wire and cable sheath material is made of high-purity resin as the base material, and is mixed with halogen-free flame retardants, antioxidants, etc. and extruded into granules. It has excellent performance such as halogen-free, heat-resistant, and weather-resistant, has no precipitation pollution, meets the relevant requirements of Rohs, and is easy to extrude and process. It can be combined with other different types of resins (PP, PE, PS, PA, etc.), flame retardants, functional additives, etc. to repolymerize and process into new elastomer materials.

Halogen-free flame-retardant TPE is a halogen-free and environmentally friendly material with phosphorus and nitrogen as flame retardant elements. The mechanical properties meet the requirements for TPE wires in UL standards, and the flame retardancy reaches UL1581VW-1, UL94V-0, V-1, V-2 and CSAFT-2, FT-1 levels. The product meets the environmental requirements of ROHS2.0, Reach, Halogen-free, PAHS, 23P-Free, PFOS&PFOA, etc.

Application fields:

Combined with different types of resins and other additives, TPE can be used in the manufacture of wires and cables in the fields of consumer electronic cables, medical cables, new energy vehicles, charging pile cables, insulated wire sheaths, wire plugs, etc. This product has good production and processing, delicate appearance, and no white precipitation.

TPE(Thermoplastic Elastomer) materials are widely used in the wire and cable industry due to their unique properties. TPE is a material between rubber and plastic. It has the high elasticity, high strength and high resilience of rubber, and can be processed by injection molding. These characteristics make the application of TPE in the wire and cable industry have many advantages.

The advantages of TPE materials include

Environmental protection and non-toxicity: TPE materials do not contain harmful substances, meet environmental protection requirements such as ROHS, and are safe materials.

Wide hardness range: TPE's hardness ranges from Shore A 0 to D 60, and the hardness can be adjusted as needed.

Weather resistance and temperature resistance: TPE materials have good weather resistance and temperature resistance and are suitable for various environmental conditions.

Excellent processing performance: TPE materials do not require vulcanization or the vulcanization time is very short, which can effectively save energy, and the processing temperature is generally between 180℃ and 220℃。

Recyclability: TPE materials can be recycled to reduce costs.

In the wire and cable industry, TPE materials are often used for the outer sheath and insulation layer of cables. Compared with traditional materials such as PVC, PE, and PUR, TPE has better flexibility and wear resistance, does not contain halogen, and does not produce toxic smoke when burned. Therefore, it is particularly suitable for applications with high requirements for environmental protection and safety performance. These characteristics of TPE materials make it widely used in products such as data cables, headphone cables, electronic cables, power cables, and signal cables.
