Is Shenzhen Toy TPE Wholesale Reliable?

TPE is processed by overmolding, common products include handles, grips, electronic materials, etc.

Transparent TPE materials have different product properties when used in different applications. Thermoplastic elastomer, also known as TPE material, not only has the processing properties of thermoplastic plastics but also the physical properties of vulcanized rubber. This is the so-called advantageous combination of plastic and rubber. Transparent TPE is widely used in people's daily life and production.

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

The material gives the product a comfortable touch, enhances grip, improves product aesthetics and added value. Most products are exported to developed countries and regions such as the United States, Japan, and the European Union.

TPE is used in overmolding, with TPE soft rubber as the soft outer covering layer,

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

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

Common matching hard materials are mainly plastics, but also metals and fabrics. TPE overmolding with fabric is mainly used in luggage products. Like overmolding with metal, it is generally false overmolding. True overmolding is often seen in two-shot injection molding and bi-color injection molding, where the main material for TPE overmolding is plastic.

The overmolding temperature is generally controlled at 30-50°C, but for some TPE grades with strong crystallinity,

To achieve the matte appearance of thermoset rubber, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) on the mold cavity will produce an excellent workpiece appearance and make 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.

Since any impurity in the TPE material can affect the transparency of the product, it is necessary to pay attention to sealing during storage, transportation, and feeding to ensure the TPE raw material is clean. Especially if the TPE raw material contains moisture, it will cause the raw material to deteriorate when heated, so it must be dried. During injection molding, a drying hopper must be used for feeding.

The mold temperature can be appropriately raised to 70°C, which is beneficial for bonding and can also achieve a more glossy overmolded surface.
