Quotation for Hunan overmolding fire retardant TPE

TPE material is used for overmolding injection, with TPE soft rubber as the soft outer layer,

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

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

Common hard materials for cooperation are mainly plastics, also metals and fabrics. TPE injection with fabric is mainly used in luggage products, similar to metal overmolding, generally pseudo-overmolding.

TPE uses overmolding injection processing, common products such as handles, grips, electronic materials, etc.

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

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

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

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

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

Styrenic transparent TPE is widely used in 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 mold temperature can be appropriately raised to 70°C, which is beneficial for bonding and can obtain a more glossy overmolded surface.
