How to choose Tianjin rubber TPE customization

TPE elastomer soft gel is applied in two-shot injection molding and overmolding.

Transparent TPE is used in appliance housings, handles, and grips, offering excellent tactile feel, non-slip and labor-saving, easy to color and process, and providing a wide design space.

To achieve the matte appearance of thermoset rubber surfaces, a rougher mold surface is required. Generally, the rough surface produced by electrical discharge machining (EDM) of the mold cavity results in excellent part appearance and makes demolding relatively easy. Abrasive 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.

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

TPE overmolding generally uses two-shot injection molding process, which involves fixing the injection-molded rigid plastic part onto the overmolding mold,

Transparent TPE is specifically a thermoplastic elastomer, while TPR, translated from English, is strictly called thermoplastic rubber, which is the basic difference. TPE is generally modified and formed from SEBS base material, while TPR is modified from SBS base material.

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, the parts should be cleaned with screw cleaner before use and after shutdown to ensure they are free of impurities.

Then, at the appropriate temperature, the TPE soft gel is injection molded and overmolded onto the rigid plastic part, and cooled to obtain the product. The injection temperature for overmolding varies depending on the rigid plastic material being overmolded.

Juye focuses on the research, development, production, and sales of TPE toy materials and TPE soft rubber,

Due to the high light transmittance of transparent TPE materials, strict surface quality requirements are necessary for the products, without any defects such as streaks, pores, whitening, halo, black spots, discoloration, or poor gloss. Therefore, throughout the injection molding process, strict and even special requirements must be placed on TPE raw materials, equipment, molds, and even product design.

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