How is Jiangxi overmolding flame retardant TPE?

A bonding layer is formed at the interface between the hard plastic and the soft rubber.

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which makes its properties very different. It has the necessary characteristics such as aging resistance and yellowing resistance required for producing transparent TPE, and also contributes to excellent properties like high temperature resistance and corrosion resistance. Only then can transparent TPE be made.

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 boards is also expanding.

Overmolding flame retardant TPE

Greatly improves the overmolding adhesion between TPE soft rubber and hard plastic. False overmolding hardly involves the compatibility of the two materials. Overmolding of materials is achieved through mechanical force, mold and product design, surface treatment, and mechanical interlocking, so that the soft rubber and hard plastic can be bonded together.

For TPE overmolding (two-shot injection molding), the key point is to achieve good adhesion between TPE and the substrate materials such as PP, ABS, PC, PA, etc. To ensure good adhesion between TPE and the substrate,

Transparent grade includes transparent and translucent series, each with various hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing performance, tear resistance, tensile strength; meets environmental requirements; suitable for various transparent series products.

Diene transparent TPE: diene 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, due to its good transparency, weather resistance, electrical insulation, and photodegradability, it is widely used in footwear, sponge, optical films, and other industrial rubber products.

Overmolding flame retardant TPE

According to the chemical principle of like dissolves like, the key is that TPE and the substrate material should have similar polarity, allowing molecular chain-level fusion between TPE and the substrate.

TPE as a raw material. TPE material manufacturers have characteristics such as environmental friendliness, non-toxicity, good elasticity, and smooth surface. Additionally,

To prevent contamination of TPE raw materials and the presence of old materials or impurities in the screw and accessory recesses, especially materials with poor thermal stability, all parts should be cleaned with screw cleaner before use and after shutdown to ensure no impurities adhere.

Transparent TPE is used in stationery, sports equipment, etc., and has good UV resistance, chemical resistance, and easy coloring and processing properties.

Overmolding flame retardant TPE

The surface is not easy to attract dust, has good thermal conductivity, and excellent anti-fouling performance. Through skin safety and non-sensitization tests, it meets the properties that silicone cannot meet, making the appearance more high-end and exquisite. TPE is positioned as the preferred high-end raw material in the industry.
