For baby and children's products, the safety and environmental friendliness of the materials are of utmost importance. Compared with other elastomer materials, the safety of PPSi® super elastic material is more convincing. TPE materials, due to the presence of rubber oil during production, have the risk of oil leaching after long-term use. However, PPSi® super elastic material is produced without oil addition, being environmentally friendly and eliminating these safety hazards at the source.

It has undergone numerous authoritative global tests and certifications, including those by SGS in Switzerland, Intertek in the UK, RoHS in the EU, FDA in the US, LFGB in Europe, DGCCRF in France, and China's food safety monitoring agency for food contact grade, etc. It does not contain bisphenol A, heavy metals, plasticizers, etc., which are harmful to the human body. This completely eliminates the risk of chemical substances entering children's bodies through drinking water. It fully meets the extremely high requirements for materials in infant and children products.

Although the sealing part of the baby water cup is very small, it is crucial for preventing leakage. Its wear resistance directly affects whether the sealing performance can be maintained for a long time. When babies use the water cup, they often open and close the lid frequently, which causes the sealing part to be constantly subjected to friction and compression. The traditional elastic material sealing part, under such long-term "torture", is prone to wear and even develop small gaps. As a result, the sealing performance is greatly compromised, and the leakage problem follows.

The PPSi® super elastomer can successfully meet this challenge, as it boasts excellent wear resistance. No matter how long it is used, it can maintain an outstanding leak-proof effect just like a new product, achieving true leak-proof safety.

Traditional silicone seals require multiple complex processes, which not only have a long production cycle but also have high requirements for production equipment and processes, leading to unstable product quality. However, PPSi® super elastomer, as a thermoplastic vulcanized silicone rubber, can replace silicone and achieve injection molding process, quickly forming high-precision seals. It can also be used for coating to form a seamless and tight structure. This processing method not only improves production efficiency but also ensures the quality of the products very well.
