Which is the best for Tianjin rubber TPE customization?

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

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

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

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

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

To prevent contamination of TPE raw materials 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.

Transparent TPE is used in stationery, sports equipment, etc. It has good UV resistance, chemical resistance, and is easy to color and process.

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

Why is TPE material a good choice for toy dolls? Thermoplastic elastomer TPE soft compounds are increasingly common in the toy industry. In the application field of toys,

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

Olefin-based transparent TPE has good weather resistance and ozone resistance, so it is the fastest-growing variety of TPE, and it is mainly used as a key rubber material in automotive, home appliances and other fields.

Traditional soft PVC material and TPR material, with their good environmental protection, safety, non-toxic and other characteristics, are increasingly welcomed and trusted by consumers. Each industry has its own corresponding standards. As far as the toy industry is concerned, it also has its own special industry standards.
