Toy is a kind of special article for playing. You can also learn some little knowledge from playing with toys. However, due to unsafe factors in some toys, many countries in the world have formulated safety standards for toys. Toys must be inspected, and if they meet the standards, they must be marked on the products. Otherwise, they are not allowed to be produced, sold or imported. Most countries adopt the International Toy Safety Standard formulated by the International Toy Industry Committee.
As the toy industry is increasingly demanding environmental protection, in addition to the usual ROHS,EN71 EN71 environmental protection standards, the number of SVHC substances of very high concern prescribed by REACH in the EU has increased to 38 in recent years. Because traditional toys mostly use PVC soft glue as raw materials, PVC soft glue is often difficult to meet ROHS,REACH,EN71 EN71 detection standards in heavy metal content detection, phthalate toxic substance detection and SVHC substances of very high concern detection projects. TPR soft adhesive meets the environmental protection standard and is a new type of environmental protection material to replace PVC soft adhesive. After years of research and development, dongguan juye plastic technology co., ltd finally developed a special food grade TPE/TPR for children's toys.
TPR soft rubber is a kind of thermoplastic elastomer, which is a composite functional material modified with SBS and SEBS as matrix materials. TPR soft adhesive used for toy production and processing and oil spray screen printing has a common hardness range of Shore 30~90A. The material can be natural color, semitransparent and transparent color, and has excellent oil spraying and silk screen printing characteristics.
TPR's Five Major Performances:
1. 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!
2. 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.
3. 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!
4. Environmental protection performance
Although most TPR materials meet ROHS and EN71-3 testing standards for environmental protection, 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!
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.
With regard to material hardness, TPR can provide a choice of materials in the hardness range of 0-100A.
Regarding the processing of TPR, injection molding and extrusion are still the main methods at present. Special TPR materials can be blow molded.
