How are flame-retardant TPE manufacturers in Shenzhen?

TPE uses overmolding injection bonding processing. Common products include handles, grips, electronic materials, etc.

TPE high-transparency material has different product properties when applied in different aspects. Thermoplastic elastomer, also known as TPE material, transparent TPE not only has the processing properties of thermoplastics but also the physical properties of vulcanized rubber, which is the advantageous combination of plastic and rubber. Transparent TPE is widely used in people's daily life and production.

Because of the high light transmittance required for transparent TPE materials, strict surface quality requirements for material products are necessary. There must be no defects such as streaks, pores, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, great attention and strict or even special requirements must be paid to TPE raw materials, equipment, molds, and even product design.

The material imparts a comfortable touch to the product, improving grip, enhancing the product's aesthetics and added value.

TPE overmolding injection bonding generally uses a two-shot injection molding process, where the injection-molded hard plastic part is fixed onto the overmolding mold.

The transparent grade is divided into transparent and translucent series, each with various softness and hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing properties, tear resistance, and tensile strength; meets environmental requirements; suitable for various transparent series products.

Transparent TPE is used in stationery, sports equipment, etc. It has good UV resistance, chemical resistance, and is easy to color and process.

Then, at a suitable temperature, the TPE soft material is injection-bonded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding bonding varies depending on the hard plastic material being overmolded.

During the molding process of TPE material, during the filling of the mold cavity,

SEBS is the product after hydrogenation of SBS. SEBS has a saturated molecular structure, which leads to very different characteristics. It has the necessary aging resistance, yellowing resistance, etc., for producing transparent TPE, and also contributes to excellent properties such as high temperature resistance and corrosion resistance. Only then is transparent TPE made.

Olefin-based transparent TPE has good weather resistance and ozone resistance, so it is called the fastest-growing variety of TPE. It is mainly used as a primary rubber material in fields such as automotive and home appliances.

If the filling performance of the product is poor, there will be too much pressure reduction, excessively long filling time, unqualified filling, etc., causing quality problems with the product.
