Where is Anhui pet toy TPR good?

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

TPE high transparent material has different product properties when applied in different aspects. 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 the advantages of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

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

Greatly improves the overmolding adhesion of TPE soft rubber and hard plastic. False overmolding almost does not involve the compatibility of the two materials. The overmolding of materials is achieved through mechanical force, through the design of molds and products and surface treatment, and through the clamping effect, so that the soft rubber and hard rubber can be bonded together.

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

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

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, therefore, before use and after shutdown, use screw cleaner to clean all parts so that they are free of impurities.

According to the chemical principle of like dissolves like, the key point is that TPE and the base material should have similar polarity, so that TPE and the base material can undergo molecular chain level fusion.

During the molding process of TPE material, during the filling of the mold cavity,

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

Transparent TPE is used in appliance casings, handles, grips, etc., exhibiting very good hand feel, anti-slip and labor-saving, easy coloring and processing, and has a wide range of design possibilities.

If the filling performance of the product is not good, there will be too much pressure reduction, too long filling time, unqualified filling, etc., causing product quality problems.
