How to choose Jiangsu wristband material TPE customization

TPE material is used for overmolding, with TPE soft rubber as the outer soft layer,

The transparent grade includes transparent and translucent series, each with multiple hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing properties, tear resistance, good tensile strength; meets environmental requirements; suitable for various transparent series products.

Diene transparent TPE is mainly an isomer of natural rubber, 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 shoemaking, sponge, optical film, and other industrial rubber products.

Commonly used hard materials are mainly plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used for luggage products, and like metal overmolding, it is generally false overmolding.

TPE overmolding generally uses a two-shot injection molding process, where the injection-molded hard plastic part is fixed onto the overmolding mold,

Due to the high light transmittance required for TPE transparent materials, strict surface quality requirements are necessary for the material products. There must be no defects such as streaks, pores, whitening, halo, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special requirements must be paid attention to and proposed for TPE raw materials, equipment, molds, and even product design.

The wall thickness of the TPE layer should be as uniform as possible to achieve the best molding cycle. Transitions between different wall thicknesses should be gradual to reduce problems caused by fluid flow, such as air lines and bubbles.

Then, at an appropriate temperature, the TPE soft rubber is injection molded onto the hard plastic part, and the product is obtained after cooling. The injection temperature for overmolding depends on the hard material being overmolded.

During the TPE material molding process, during the filling of the mold cavity,

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which leads to very different properties. It has the necessary aging resistance, anti-yellowing properties, etc., required for producing transparent TPE, and also contributes to excellent high-temperature resistance and corrosion resistance. This is how transparent TPE is made.

Transparent TPE is used in appliance casings, handles, grips, etc. It exhibits a very good hand feel, is slip-resistant and labor-saving, easy to color and process, and offers a wide design space.

If the filling performance of the product is poor, there will be too much pressure reduction, excessively long filling time, unqualified filling, etc., causing quality problems in the product.
