According to different toy products, there are no requirements for the physical properties and processing properties of TPR soft rubber. In fact, TPR is just an extension of soft PVV resin, but the compression deformation should be greatly improved, thus forming rubber-like PVC. This TPR can be regarded as a modified PVC and a substitute for rubber. So what are the advantages of Dechuang Chemical TPR vent toy materials?
1. Environmental Protection Performance: Although most TPR materials conform to ROHS and EN71-3 testing standards, the testing standards for toy products are still different 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 the environmental protection requirements when mixing TPR compound.
2. Excellent color matching performance: Soft plastic toy products are mostly colorful and have high 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 spray painting: Most toy products have requirements for screen printing of spray painting. 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 for elasticity: Some toy products have high requirements for stretch and tear resistance, and some toy products have good requirements for resilience, etc. In short, the most suitable TPR materials shall be provided according to the specific requirements of the customers.
6. Good molding and processing performance: TPR material has moderate fluidity, convenient molding and processing, injection molding temperature of 170~190℃, and is not prone to shrinkage, burrs and other molding appearance problems. 、
With so many advantages, TPR's advantages in relation to the toy industry are also reflected and are worthy of the trust of the toy industry.
