Where are good transparent TPE manufacturers in Beijing?

TPE overmolding usually adopts the two-shot injection molding process,

Since any impurity in the TPE material may affect the transparency of the product, attention must be paid to sealing during storage, transportation, and feeding to ensure the TPE raw material is clean. Especially if the TPE raw material contains moisture, heating will cause the material to deteriorate, so it must be dried. During injection molding, a drying hopper must be used for feeding.

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

Fix the already molded (injected) rigid plastic part onto the overmolding mold, then at a suitable temperature, inject and bond the TPE soft material onto the rigid part, and obtain the product after cooling. The injection temperature for overmolding differs according to the rigid material being overmolded.

PP overmolding is a plastic with very weak polarity, which is very close to the polarity of TPE based on SEBS.

TPE is a classic aggregation-induced emission molecule, meaning it has no fluorescence in solution but strong fluorescence in solid state. Therefore, transparent TPE materials also have important applications in fields such as organic optoelectronics.

Styrenic transparent TPE is widely used in the footwear industry, largely replacing rubber; at the same time, its use in industrial rubber products such as adhesive tapes and rubber sheets is also expanding.

Therefore, for PP overmolding, the most conventional TPE formula can be used directly without adding any polarity modifier.

The temperature in the feeding zone should be set quite low to prevent blockage of the feed inlet and allow entrained air to escape.

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

Transparent TPE is used in appliance housings, handles, grips, etc. It exhibits very good hand feel, is anti-slip and labor-saving, and is easy to color and process. It also has a wide design space.

To change the mixing state, the temperature in the transition zone should be set above the melting point of the masterbatch, so as to change the mixing state when using the masterbatch. The temperature near the nozzle should be set close to the required melting temperature.
