Each industry has its own standards, and as far as the toy industry.
is concerned, it also has its own special industry standards. Moreover, different toy products have different requirements for the physical properties and processing properties of TPR soft rubber materials. The reason why TPR can replace a lot of PVC materials in the toy industry. is mainly because TPR has the following characteristics:
Environmental performance
Although the environmental characteristics of most TPR materials are in line with ROHS and EN71-3 test standards, different countries or regions have different testing standards for toy products. Some requirements do not contain PAHs polycyclic aromatic hydrocarbons, do not contain NP(nonylphenol), etc., and some requirements do not contain SVHC high concern substances stipulated by REACH. This requires full consideration of environmental protection requirements in the mixing of TPR adhesives!
Good oil injection screen printing performance
Most toy products have the requirement of oil spray paint screen printing. In order to obtain excellent oil spray screen printing effect (paint spray does not fall off), the matching of TPR adhesive and ink paint is very important, and the appropriate paint ink should be selected according to the characteristics of TPR.
Cracking resistance of soft toys
For some soft toys with very soft hardness, attention should be paid to the selection of appropriate TPR materials to prevent cracking after product processing. In addition, through the optimization and improvement of the forming process, the cracking caused by stress contraction is reduced! Some toy products have high requirements for tensile and tear resistance, and some toy products have good requirements for resilience and so on. In short, the most appropriate TPR materials should be provided according to the specific requirements of customers.
Excellent color matching performance
Soft rubber toy products are mostly bright and diverse colors, and there are high requirements for the color matching of TPR materials. A qualified TPR grade, should have good color pink agent diffusion performance and conducive to color powder can be better coloring, to achieve the color as bright as possible, uniform color matching effect!
