How to choose Guangdong fireproof TPE manufacturers

TPE elastomer soft glue is used for secondary injection molding, overmolding and injection bonding.

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. In particular, if the TPE raw material contains moisture, it will cause deterioration when heated, so it must be dried. During injection molding, a drying hopper must be used for feeding.

Transparent TPE materials have 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 has the physical properties of vulcanized rubber. This is the advantageous combination of plastics and rubber. Transparent TPE is widely used in people's life and production.

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

TPE overmolding, as the name implies, is to overmold TPE soft material onto other materials.

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

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

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 generally handles and grips. TPE soft material has a special comfortable touch, and the introduction of TPE material improves the grip and touch feel of products.

The overmolding temperature is generally controlled at 30-50°C, but for some highly crystalline TPE grades,

Transparent TPE is used in appliance housings, handles, and grips, etc. It shows very good hand feel, is slip-resistant and labor-saving, and has the characteristics of easy coloring and processing. It also has a wide design space.

Diene-based transparent TPE, diene-based TPE is mainly an isomer of natural rubber, so it is 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.

The mold temperature can be appropriately raised to 70°C, which is beneficial for bonding and can also obtain a more glossy overmolded surface.
