The TPE commonly referred to in the elastomer industry is a composite functional material obtained by modifying SEBS.
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 rubberized fabric and rubber sheets is also expanding.
To achieve the matte appearance characteristic 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 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 create surfaces with different gloss levels and appearances.

PP overmolding is a plastic with very weak polarity, which is very close to the polarity of SEBS-based TPE.
The wall thickness of TPE material should be as uniform as possible to achieve the best molding cycle. The transition between different wall thicknesses should be gradual to reduce fluid flow problems, such as gas marks and bubbles.
To prevent contamination of TPE raw materials and the presence of old materials or impurities in the recesses of the screw and accessories, especially materials with poor thermal stability, it is necessary to clean all parts thoroughly with a screw cleaner before use and after shutdown to ensure no impurities adhere.

The overmolding temperature is generally controlled at 30-50°C, but for some TPE grades with strong crystallinity,
Transparent TPE is used in appliance housings, handles, and grips, etc. It exhibits very good hand feel, is anti-slip and labor-saving, and has the characteristics of easy coloring and processing, as well as a wide design space.
Since any impurity in TPE material can affect the transparency of the product, sealing must be ensured during storage, transportation, and feeding to keep the TPE raw material 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.
