Hello, everyone, I'm Zhanghuimin, I speak for TPE/TPR/TPU / TPEE / materials! For a long time, and even now, many soft plastic dolls(especially in the domestic market) have used soft PVC as a raw material. However, in recent years, many PVC toys have been subject to more and more restrictions. Why?
The original soft PVC material usually contains a class of plasticizers called phthalates(including esters and their compounds, common such as DEHP, DBP, DOP, etc.). These substances have been tested by numerous experiments at home and abroad. Proved to have severe reproductive toxicity. Regarding its harm, the author of this article does not elaborate, interested readers can refer to Baidu Encyclopedia entry-phthalates.
In recent years, for PVC soft toy phthalates testing standards, Europe and the United States and other developed countries have issued relevant toy products environmental protection inspection laws and regulations. For the toy industry, there are currently environmental PVC(plasticizers and stabilizers) that meet the requirements for environmental protection without phthalates and heavy metals on the market, in line with ROHS, EN71-3 and REACH(SVHC). Environmental PVC. Although environmentally friendly PVC can meet the export requirements of the toy industry, its cost is relatively high, and the market price is about 14 yuan and one kilogram. The specific gravity is about 1.22. At present, the TPR environmentally friendly soft gum material that appears on the market has a weight of 1.02, a price of 16 yuan per kilogram, a weight of 0.95, and a price of 19 yuan per kilogram. In this way, the cost of TPR materials is comparable to that of PVC.
TPR is more environmentally friendly and more cost-effective. However, TPR soft adhesive material does not contain phthalate PAEs, except that it does not contain bisphenol A(BPA), does not contain nonylphenol NP, does not contain PAHs(polycyclic aromatic hydrocarbons), does not contain POFA(Perfluoroctyl ammonium), in line with EN 71, REACH(SVHC), ROHS2 .0 and other environmental protection test standards. The Environmental Protection level of TPR is above environmental protection PVC.
Compared with PVC, TPR is more comfortable and tasteless. At present, PVC materials on the market are varied, and it is inevitable that the good and bad are uneven, and sometimes even the environment is worrying. The use of advanced environmental protection TPR(TPE), instead of PVC, is undoubtedly more secure for toy exporting companies, and the cost of materials is also similar. It can be said that TPR has a higher value for money.
Moderate TPR, non-corrosive equipment, according to a toy factory friend, their injection molding machine will be renovated every three months to six months due to the use of ordinary twin screw(non-Titanium magnesium alloy screw). It is suspected that PVC materials will corrode the screw(or due to the release of acidic substances HCL at high temperatures), and after using a mild TPR material, the screw has not been used for a year.
