How about the cost of Tianjin rubber TPE supplier?

TPE elastomer soft gel is used for secondary injection molding, overmolding.

Transparent TPE material has different product properties when applied in different areas. Thermoplastic elastomer, also called TPE material, not only has the processing properties of thermoplastic plastics, but also the physical properties of vulcanized rubber. This is the advantageous combination of the merits of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

Thickness of TPE/TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good adhesion. If the TPE layer is too thin, injection molding is more difficult, adhesion strength is lower, and hand feel is poor. If the TPE layer is too thick, on one hand the cost is higher, on the other hand it is prone to defects such as sink marks, bubbles, etc.

Because TPE material has good anti-slip properties and excellent elastic touch, it can improve the tactile feel of products and enhance grip.

TPE overmolding usually adopts a two-shot injection molding process, i.e., fixing the injection-molded rigid plastic part onto the overmolding mold,

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.

Since any impurity in TPE material can 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 it to deteriorate, so it must be dried. During injection molding, a drying hopper must be used for feeding.

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

The temperature in the feeding zone should be set quite low to avoid blocking the feed throat and to allow trapped air to escape.

To prevent contamination of TPE raw material and accumulation of old material or impurities in the screw and accessory recesses, especially materials with poor thermal stability, all parts should be cleaned with screw purging compound before use and after shutdown to ensure no impurities adhere.

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which gives it very different characteristics. It has the necessary aging resistance, yellowing resistance, and other properties required for producing transparent TPE, and also contributes to excellent heat and corrosion resistance. Only then can transparent TPE be made.

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