Best thermoplastic elastomer in Tianjin

TPE elastomer soft gel can be adjusted to suitable hardness (hardness range Shore 25-90A) according to the physical property requirements of the product.

Transparent TPE is used in appliance casings, handles, grips, etc. It offers excellent hand feel, non-slip and labor-saving properties, and is easy to color and process, providing a wide design space.

Transparent TPE material has different product properties in different applications. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing properties of thermoplastic plastics but also the physical properties of vulcanized rubber, which is a combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

And suitable physical properties (such as wear resistance, scratch resistance, adhesion, melt index, etc.). It provides various possible material application solutions for different products.

TPE is used in overmolding and injection bonding, with TPE soft gel as the outer covering layer.

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

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, it is widely used in shoemaking, sponge, optical film, and other industrial rubber products due to its good transparency, weather resistance, electrical insulation, and photodegradability.

Thermoplastic elastomer

Commonly matched hard materials are mainly plastics, also metals and fabrics. TPE injection bonding with fabric is mainly used in luggage products, similar to metal overmolding, generally false overmolding. True overmolding is more common in two-shot injection and two-color injection, where the main material for TPE overmolding is plastic.

The temperature in the feeding zone should be set quite low to avoid blocking the feed port and to allow trapped air to escape.

Since TPE transparent material requires high light transmittance, the surface quality of the material product must be strictly controlled, without any defects such as streaks, air bubbles, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special requirements must be paid attention to for TPE raw materials, equipment, molds, and even product design.

Since any impurity in the TPE material may affect the transparency of the product, it must be sealed during storage, transportation, and feeding to ensure the cleanliness of the TPE raw material. In particular, if the TPE raw material contains moisture, heating will cause the raw material to deteriorate, so it must be dried. During injection molding, a drying hopper must be used for feeding.

Thermoplastic elastomer

To change the mixing state, the temperature in the transition zone should be set above the melting point of the masterbatch, so as to change the mixing state when using masterbatch. The temperature near the nozzle should be set close to the required melting temperature.
