How to choose a transparent TPE supplier in Hunan

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

Transparent grades are divided into transparent and semi-transparent series, each with various hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing performance, tear resistance, and tensile strength; meets environmental requirements; suitable for various transparent series products.

Styrene-based transparent TPE is widely used in the footwear industry, largely replacing rubber; at the same time, its applications in industrial rubber products such as rubber sheets and rubber plates are also expanding.

<\/p>Due to the good slip resistance of TPE material and excellent elastic touch, it can improve the tactile feel of the product and enhance grip.<\/p>

TPE overmolding and injection bonding generally adopts a secondary injection molding process, that is, fixing the injection-molded rigid plastic part on the overmolding mold,

Transparent TPE is used in appliance shells, handles, grips, etc., exhibiting very good hand feel, anti-slip and labor-saving, easy to color and process, and has a wide design space.<\/p>

Due to the high light transmittance required for transparent TPE materials, strict requirements are imposed on the surface quality of material products; no defects such as streaks, pores, whitening, haze, black spots, discoloration, poor gloss, etc. are allowed. Therefore, throughout the injection molding process, great attention and strict even special requirements must be given to TPE raw materials, equipment, molds, and even product design.<\/p>Transparent TPE Supplier

<\/p>Then, at the appropriate temperature, the TPE soft gel is injection-bonded onto the rigid plastic part, and the product is obtained after cooling. The injection temperature for overmolding and injection bonding varies depending on the rigid plastic material being overmolded.<\/p>

For secondary injection overmolding of nylon using an ordinary injection molding machine, it is recommended to preheat and bake the nylon part before overmolding,

Diene-based transparent TPE, diene-based TPE is mainly an isomer of natural rubber, so it is 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 footwear, sponge, optical films, and other industrial rubber products.<\/p>

The wall thickness of the TPE rubber part should be as uniform as possible to achieve the optimal molding cycle. The transition between different wall thicknesses should be gradual to reduce fluid flow problems such as gas marks and bubbles.<\/p>Transparent TPE Supplier

<\/p>First, preheat and bake the nylon part because nylon has strong water absorption and overmolding requires high molding temperature; preheating before overmolding can remove moisture, facilitating rapid hot overmolding.<\/p><\/div>
