Are Shenzhen TPR material supplier prices favorable?

In the elastomer industry, TPE usually refers to a composite functional material modified from SEBS.

Since any impurity in TPE material may affect the transparency of the product, attention must be paid to sealing during storage, transportation, and feeding to ensure that TPE raw materials are clean. Especially when TPE raw materials contain moisture, heating will cause deterioration, so they must be dried. During injection molding, a drying hopper must be used for feeding.

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

TPE elastomer soft gel has excellent comprehensive performance and is the most commonly used soft gel material for secondary injection molding, overmolding, and two-color injection molding.

POM overmolding of POM. Although POM has a low melting point of only 180℃.

Transparent TPE, specifically, is a thermoplastic elastomer, while TPR is translated from English and strictly speaking is called thermoplastic rubber. This is the most basic difference. TPE is generally formed by modifying the basic material SEBS, while TPR is modified from the basic material SBS.

Transparent TPE is used in appliance casings, handles, grips, etc. It offers excellent touch, is anti-slip and labor-saving, and is easy to color and process. It also has a wide design space.

However, due to its high crystallinity, forming a fusion layer on the overmolding surface requires high energy. Meanwhile, the self-lubricating property of POM is not conducive to the rapid coating of TPE material on the surface of POM hard plastic parts.

Preheating the insert before overmolding helps improve the adhesion strength,

To achieve the matte appearance typical 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. Grinding 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.

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

Because the preheating process can improve the compatibility of the insert material with TPE. The appropriate temperature for the insert should be determined through discussion with the material supplier.
