How are the quotes from Hubei toy TPE manufacturers?

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

Transparent grades are divided into transparent and semi-transparent series, each with various softness and hardness; excellent transparency; smooth and soft surface; good anti-yellowing performance, tear resistance, tensile strength; environmentally friendly; suitable for various transparent series products.

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

And suitable physical properties (such as abrasion and scratch resistance, adhesion, melt index, etc.). Provide various approximate material application plans for different products.

PP overmolding is a plastic with very weak polarity, very close to the polarity of TPE based on SEBS.

To produce the matte appearance of thermoset rubber surface, a rougher mold surface is required. Generally speaking, the rough surface produced after electric discharge machining (EDM) of the mold cavity will produce excellent workpiece appearance and make demolding relatively simple. Grinding methods such as steam blasting, sandblasting, shot blasting, and chemical etching can also be used to produce surfaces with different gloss and appearance.

Diene transparent TPE, diene TPE is essentially 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 shoemaking, sponges, optical films, and other industrial rubber products.

Therefore, for PP overmolding, just use the most conventional TPE formula directly, without adding additional polar modifiers.

TPE is used in overmolding injection bonding, with TPE soft gel as the soft outer covering layer,

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

To prevent contamination of TPE raw materials and the presence of old materials or impurities in the screw and attachment recesses, especially materials with poor thermal stability, before use and after shutdown, all parts should be cleaned with screw cleaner to ensure they are free of impurities.

Common hard materials for bonding are mainly plastics, also metals and fabrics. TPE injection bonding with fabrics is mainly used in luggage products, similar to metal overmolding, generally it is false overmolding. True overmolding is more common in secondary injection molding and two-color injection molding, that is, the main material of TPE overmolding injection bonding is plastic.
