How is Jiangsu Pet Toy TPR?

TPE uses overmolding (injection molding over a substrate) process. Common products include handles, grips, electronic materials, etc.

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which leads to very different characteristics. It has the necessary aging resistance, yellowing resistance for producing transparent TPE, and also promotes excellent heat and corrosion resistance. That is how transparent TPE is made.

The material gives the product a comfortable touch, improves grip, enhances aesthetics, and adds value. Most products are exported to developed countries and regions such as the United States, Japan, and the European Union.

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

Transparent TPE is specifically a thermoplastic elastomer, while TPR is translated from English and strictly speaking is called thermoplastic rubber. That is the most basic difference. TPE is generally made from SEBS base material, while TPR is made from SBS base material.

According to the principle of 'like dissolves like' in chemistry, the key is that TPE and the substrate must have similar polarity, so that they can fuse at the molecular chain level.

TPE material has good fluidity and is mainly injection molded.

Since any impurities in TPE material can affect the transparency of the product, care must be taken to seal and keep the TPE raw material clean during storage, transportation, and feeding. In particular, if TPE raw material contains moisture, heating will cause deterioration, so it must be dried. During injection molding, a drying hopper must be used for feeding.

TPE semi-finished toy products can be used for post-processing such as painting (spray painting, inkjet), screen printing, etc. Our company produces and sells TPE soft compounds, which can be used for injection molding to produce soft toys, simulated animal toys, plant toys, fruit toys, etc. The TPR provided has excellent color matching and oil spray properties, is environmentally friendly and non-toxic. Next, let's see what surprises TPE toy manufacturers bring us.
