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

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 rubber sheets and plates is also expanding.

Diene transparent TPE, diene TPE is 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 footwear, sponge, optical films, and other industrial rubber products.

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

PP overmolding is a very weak polarity plastic, and its polarity is very close to that of TPE with SEBS base.

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

To achieve the matte appearance of thermoset rubber, a rougher mold surface is required. Generally speaking, the rough surface produced by 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 produce surfaces with different gloss and appearance.

Therefore, for PP overmolding, the most conventional TPE formulation can be used directly, without the need to add additional polar modifiers.

The overmolding temperature is generally controlled at 30-50°C, but for some TPE grades with strong crystallinity,

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

The transparent grade includes transparent and translucent series, each with various hardness levels; excellent transparency; smooth and soft surface; good yellowing resistance, tear resistance, tensile strength; environmentally friendly; suitable for various transparent series products.

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