How to choose Hunan thermoplastic TPE wholesale

TPE is processed by overmolding with injection bonding. Common products include handles, grips, electronic materials, etc.

TPE high-transparent materials are used in different aspects with different product properties. Thermoplastic elastomer, also called TPE material, transparent TPE not only has the processing properties of thermoplastic plastics but also has the physical properties of vulcanized rubber. This is the so-called advantageous combination of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

The thickness of the TPE, TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good adhesion. If the TPE layer is too thin, injection molding is more difficult, adhesion strength is low, and hand feel is poor. If the TPE layer is too thick, on one hand the cost is higher, on the other hand it is prone to shrinkage, bubbles and other defects.

The material gives the product a comfortable touch, improves grip, enhances product aesthetics and product 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 injection bonding, with TPE soft rubber as the soft outer layer,

Olefinic transparent TPE has good weather resistance and ozone resistance, so it is called the fastest developing variety of TPE. It is mainly used as a major rubber material in fields such as automobiles and home appliances.

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

Commonly matched rigid materials are mainly plastics, also metals and fabrics. TPE injection bonding with fabric is mainly used in luggage products. Like metal overmolding, it is generally false overmolding. True overmolding is more common in secondary injection molding and two-color injection molding, where the main material of TPE overmolding injection bonding is plastic.

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

Styrenic transparent TPE is widely used in the footwear industry, largely replacing rubber. At the same time, its use in industrial rubber products such as rubber sheets and plates is also expanding.

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 fluid flow problems such as gas marks and bubbles.

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