Product information:

Selection of materials for new energy high-voltage wires

TPE

The types of TPE are: styrenes, olefins, dienes, vinyl chlorides, polyesters, esters, amides, organic fluorines, silicones and vinyls (TPS, TPU, TPO, TPV, etc.) ).

Most of the current use refers to SEBS-based elastomers. TPE material used in charging gun cable

Advantages: The processing technology is simple, the density is small, the price is moderate, the overall cable is very soft, and can meet the requirements of the existing standards.

Disadvantages: most contain unsaturated bonds, poor temperature stability; low oil resistance, especially gasoline; poor weather resistance, poor thermal stability of materials for long-term use, mechanical properties of materials drop a lot under high temperature conditions,

There is a high risk of cracking when used outdoors; intolerant of dirt and sticky hands.

Parameters:

Working temperature: cold resistance -50 degrees; temperature resistance within 120 degrees.

TPU

TPU, that is, thermoplastic polyurethane elastomer, molecular structure is divided into polyester type and polyether type, composed of rigid blocks and flexible segments, injection molding accounts for more than 40% in the processing process, extrusion molding is about 35% ; The spring extension length can reach 2-6 times the original spring length.

The polyurethane sheath material of the charging pile cable is made of TPU resin, which is added with environmentally friendly or halogen-free flame retardants, antioxidants and other additives after mixing, plasticizing and granulating. It is flexible and resistant to rolling. Withstand voltage, high temperature pressure, aging resistance, acid and alkali resistance, salt spray resistance, waterproof and other characteristics.

Advantages: It has excellent high tension, high tension, toughness and aging resistance, environmentally friendly materials.

Disadvantages: At present, domestic processing is difficult, there are fewer raw material enterprises, and the cost is higher.

Working temperature: cold resistance -40 degrees; temperature resistance within 150 degrees.

Polyvinyl chloride elastomer

PVC polyvinyl chloride cable, based on polyvinyl chloride, can be adjusted by adding different amounts of plasticizers to adjust its softness and reduce its "glass transition" temperature, thereby having good flexibility and increasing plasticity. Make it easy to process.

After cross-linking, the chain segments form a network structure, and the elastic expansion and contraction length can reach 2-4 times of the original spring length.

Advantages: flame retardant and insulation, acid resistance, oil resistance, easy processing and modification, and cheap.

Disadvantages: There will be black smoke and HCl gas when burning.

Working temperature: cold resistance -40 degrees; temperature resistance within 105 degrees (according to customer requirements).
