In recent years, it has been widely used in the field of toys, from toy tires to toy figures or doll accessories. Many toys such as various elastic ball games, luminous animal dolls, mollusks and simulated fruits are generally made of TPR .TPE materials can not only replace all kinds of thermosetting rubber, silica gel and PVC, but also bring more inspiration to toy designers due to its unique performance, thus designing more novel and diversified toys and increasing the added value of products. The soft hardness of the product ranges from 0.5 degrees to 10 degrees and less than 20 degrees, which is very popular with toy designers. 1. Determine the hardness of TPE.TPR materials Regarding the determination of hardness, the general user will provide an OK template. TPE.TPR material manufacturers can test the hardness of the sample plate. The soft hardness of TPE.TPR material produced by Juhui has customers' choice from 0A to 100A. So as to determine the TPE.TPR material product model with appropriate hardness. If the user does not have a physical sample, only provides a picture of the product and provides a hardness number, it is best to determine whether the hardness refers to PVC hardness P or Shore A. With the same value, the actual hardness represented by P and A are different. 2. Is it necessary to inject oil It should be confirmed whether the toy doll products processed by the user need oil spray screen printing. For screen printing with oil injection, it is recommended to select TPE.TPR material product brand that is easy to inject oil (whether oil injection is good depends on the characteristics of the paint. SBS and SEBS are currently used as adhesive resins in most paints on the market, which is related to the selection of TPE.TPR material). 3. Confirm the environmental protection testing requirements of export market The toy industry generally needs EN71-3. Some requirements conform to the latest REACH(SVHC), while others require detection of PAH s (polycyclic aromatic hydrocarbons), nonylphenol (NP), bisphenol A(BPA), phthalate (16P,6P), etc. Environmental testing requirements shall be confirmed as the basis for selecting materials. Juhui TPE.TPR has tested these test standards every year. 4. Color matching requirements If users require bright color matching, TPE.TPR materials of SBS and SEBS substrates can be used, and the proportion of filling system is preferably less. 5. Processing issues In other aspects, if problems such as shrinkage and lack of glue cape occur in injection molding, fluidity and shrinkage can also be adjusted from the perspective of raw materials. In particular, the former mould of the user is used for processing PVC, but now the mould is not modified and is directly used for processing TPE.TPR materials, and the selection of TPE.TPR materials is more exquisite.
