What are the transparent TPE suppliers in Zhejiang

In the elastomer industry, TPE generally refers to composite functional materials modified with SEBS.

Since any impurity in TPE material may affect the transparency of the product, it is necessary to pay attention to sealing during storage, transportation, and feeding to ensure the cleanliness of TPE raw materials. Especially if TPE raw materials contain moisture, heating will cause the material to deteriorate, so they must be dried. During injection molding, a dry hopper must be used for feeding.

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 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.

TPE elastomer soft rubber has excellent comprehensive properties and is the most commonly used soft rubber material for two-shot injection molding, overmolding, and two-color injection molding.

PP overmolding is a plastic with very weak polarity, which is very close to the polarity of TPE based on SEBS.

The wall thickness of the TPE cavity should be as uniform as possible to achieve the best molding cycle. The transitions between different wall thicknesses should be gradual to reduce problems caused by fluid flow, such as gas marks and bubbles.

Transparent TPE of styrene type is widely used in the footwear industry, replacing most of the rubber; at the same time, its use in industrial rubber products such as rubber sheeting and rubber plates is also expanding.

Therefore, for PP overmolding, the most conventional TPE formula can be used directly without adding additional polar modifiers.

TPE material has good fluidity and is mainly used for injection molding.

SEBS is the product of hydrogenated SBS. SEBS has a saturated molecular structure, which leads to its very different characteristics. It has the necessary properties for producing transparent TPE, such as aging resistance and yellowing resistance, and also contributes to excellent properties like high temperature resistance and corrosion resistance. This is how transparent TPE is produced.

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