How about the quotation of Tianjin flame-retardant TPE manufacturers?

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

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 formed by modifying the base material SEBS, while TPR is made from SBS base material.

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.

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

TPE overmolding injection generally adopts a two-shot injection molding process, that is, the injection-molded hard plastic part is fixed on the overmolding mold,

Because transparent TPE material requires high light transmittance, the surface quality of the product must be strictly controlled, without any defects such as streaks, air bubbles, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, during the entire injection molding process, strict and even special attention must be paid to the TPE raw material, equipment, mold, and even product design, and strict requirements must be proposed.

To achieve the matte appearance of thermoset rubber, a rougher mold surface is required. Generally speaking, the rough surface produced by electrical discharge machining (EDM) of the mold cavity will result in an excellent workpiece appearance and make demolding relatively easy. Abrasive methods such as steam blasting, sandblasting, or shot blasting, as well as chemical etching, can also be used to create surfaces with different gloss and appearance.

Then, at a suitable temperature, the TPE soft rubber is injection overmolded onto the hard plastic part, and after cooling, the product is obtained. The injection temperature for overmolding varies depending on the hard plastic material being overmolded.

Preheating the insert before overmolding helps improve the bonding strength,

Transparent TPE is used in household appliance shells, handles, grips, etc. It exhibits very good hand feel, is anti-slip and labor-saving, and has the characteristics of easy coloring and processing. It also has a wide design space.

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

Because the preheating process can improve the compatibility between the insert material and TPE. The appropriate temperature for the insert needs to be discussed and determined with the material supplier.
