How to choose Tianjin raw material TPE manufacturer

TPE elastomer soft gel is used in two-shot injection molding and overmolding.

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

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

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, as the name suggests, is the process of overmolding TPE soft gel material onto other materials.

Transparent TPE specifically refers to thermoplastic elastomer, while TPR is translated from English and strictly speaking is called thermoplastic rubber. This is the most basic difference. TPE is generally modified from SEBS base material, while TPR is modified from SBS base material.

Dienic transparent TPE is an isomer of natural rubber, also called thermoplastic trans-natural rubber. Although its heat resistance and mechanical strength are not as good as rubber, due to its good transparency, weather resistance, electrical insulation, and photodegradability, it is widely used in shoemaking, sponges, optical films, and other industrial rubber products.

Common processing methods include one-shot molding with a two-color injection molding machine, or using a regular injection molding machine with an overmolding mold for two-shot injection molding. TPE overmolded products are typically handles and grips. TPE soft gel material provides a special comfortable touch, and the introduction of TPE material enhances the grip and tactile feel of the products.

The temperature in the feed zone should be set quite low to avoid blocking the feed inlet and allow entrained air to escape.

To achieve the matte appearance typical of thermosetting rubber surfaces, a rougher mold surface is required. Generally, the rough surface produced after electrical discharge machining (EDM) of the mold cavity will result in excellent workpiece appearance and make demolding relatively easy. Grinding methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to produce surfaces with different gloss and appearance.

Transparent grade includes transparent and translucent series, each available in various hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing performance, tear resistance, and tensile strength; environmentally friendly; suitable for various transparent series products.

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