Product details
TPE/TPR soft adhesive is widely used in toy industry. In the application field of toys, which are traditional soft PVC materials, TPE/TPR materials are winning more favor and trust from consumers with their better environmental protection, safety and non-toxicity characteristics. Each industry has its own corresponding standards, and as far as the toy industry is concerned, there are also its own special industry standards. Moreover, different toy products have different requirements on the physical and processing properties of TPR soft adhesive.
1. Environmental Protection Performance
Although most TPE/TPR materials conform to ROHS and EN71-3 testing standards for environmental protection, there are still differences in testing standards for toy products in different countries or regions. Some requirements do not contain PAHs, polycyclic aromatic hydrocarbons, NP (nonylphenol), etc., and some requirements do not contain SVHC substances of high concern specified by REACH. This requires full consideration of environmental protection requirements when compounding TPE/TPR compound!
2. Excellent color matching performance
Soft rubber toy products are mostly of bright and varied colors, and have higher requirements for color matching of TPR materials. A qualified TPR brand should have good color pink agent diffusion performance and be conducive to better coloring of toner, so as to achieve the color matching effect of bright color and uniform color as far as possible!
3. Good screen printing performance of oil spray painting
Most toy products have the requirements of spray painting and silk screen printing. In order to obtain good screen printing effect (paint does not fall off when sprayed), the matching of TPR compound and ink paint is very important, and appropriate paint ink should be selected according to the characteristics of TPR.
4. Cracking Resistance of Soft Toys
For some soft toys with very soft hardness, appropriate TPR materials should be selected to prevent cracking after processing. In addition, through optimization and perfection of molding process, cracking caused by stress shrinkage can be reduced!
5. Other Requirements
Some toy products have high requirements for stretch and tear resistance, others have good requirements for resilience, etc. In short, the most suitable TPR materials shall be provided according to the specific requirements of the customers.
