How to choose Jiangsu overmolding fireproof TPE

TPE elastomer soft gel can be adjusted to appropriate hardness according to product property requirements (hardness range Shore 25-90A),

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which leads to very different characteristics of SEBS. It has the necessary aging resistance, yellowing resistance and other traits for producing transparent TPE, and also promotes excellent properties such as high temperature resistance and corrosion resistance. Only then transparent TPE is manufactured.

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

and appropriate physical properties (such as abrasion and scratch resistance, adhesion, melt index, etc.). It provides various approximate material application solutions for different products.

TPE overmolding (two-shot injection molding) key point is to make TPE and the coated substrate PP, ABS, PC, PA etc. have good adhesion. To achieve good adhesion between TPE and coated substrate,

TPE transparent material, due to its high light transmittance, requires strict surface quality of the product, without any defects such as streaks, pores, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special attention must be paid to TPE raw materials, equipment, molds, and even product design.

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

According to the chemical principle of similar miscibility, the key is that TPE and the coated substrate should have similar polarity, so that TPE and the coated substrate can undergo molecular chain level fusion.

TPE is used for overmolding injection bonding, with TPE soft gel as the outer soft cover layer,

Transparent TPE material has different product properties in different applications. Thermoplastic elastomer is 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 advantageous combination of plastic and rubber. Transparent TPE is widely used in people's daily life and production.

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

Overmolding fireproof TPE

Common hard materials used with TPE are mainly plastics, also metals and fabrics. TPE injection bonding with fabric is mainly used in luggage products. Same as metal overmolding, it is generally false overmolding. True overmolding is more common in two-shot injection molding and bi-color injection molding, where the main material for TPE overmolding injection bonding is plastic.
