How to Choose Fujian Fireproof Overmolding TPE

TPE overmolding generally uses a two-shot injection molding process.

The transparent grade is divided into transparent and translucent 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.

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

Fix the already injection-molded hard plastic part onto the overmolding mold, then inject and bond the TPE soft material onto the hard part at an appropriate temperature, and cool to obtain the product. The injection temperature for overmolding varies depending on the hard material being overmolded.

Overmolding of POM onto POM. Although POM has a low melting point of only 180°C.

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 fields such as organic optoelectronics.

However, due to its high crystallinity, high energy is required to form a fusion layer on the covering surface. At the same time, the self-lubricating property of POM is not conducive to the rapid covering of TPE material on the POM hard plastic surface.

TPE material has good fluidity and is mainly injection molded.

Styrenic transparent TPE is widely used in the footwear industry, mostly replacing rubber; at the same time, its use in industrial rubber products such as rubber sheets and boards is also expanding.

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