What are the materials used in the production of plastic water bottles? PPSU article? (I)

Hello everyone, "Dong Dong Talk Cup" is here. Among the many plastic water cups, there is a special type of product, which is plastic water cups used by infants, young children, and children. http://www.zhanyict.com/en/ProductsDetail-IR-10080.htmlSome materials used as adult plastic water bottles cannot be directly used for infants and children, mainly because some components in the materials are harmful to infants and children.

The plastic water cup materials used in the production of infants and children are not only food grade, but also require baby grade, so there are relatively few materials that meet the needs of infants and children's plastic water cups. http://www.zhanyict.com/en/ProductsDetail-IR-10080.htmlPPSU is one of them. Today, the editor will share with you the characteristics and advantages and disadvantages of PPSU.

PPSU, polyphenylene sulfide, is a high-performance thermoplastic engineering plastic known for its excellent heat resistance and mechanical strength. http://www.zhanyict.com/en/ProductsDetail-IR-10080.htmlPPSU is widely used in medical equipment that requires high temperature sterility, as well as in food contact and baby products, including plastic water bottles, plastic children's tableware, etc.

What are the characteristics of PPSU?

High heat resistance, PPSU can withstand continuous use temperatures up to 180 ° C, and can withstand even higher temperatures for a short period of time, making it very suitable for applications that require frequent high-temperature disinfection. http://www.zhanyict.com/en/ProductsDetail-IR-10080.htmlTherefore, PPSU made water cups for infants and children can be disinfected in a disinfection cabinet or boiled in water.

However, it should be noted that when boiling in water for disinfection, PPSU material water cups should be fixed in the boiling container as much as possible with other tools to avoid boiling and causing the water cup to move inside the container. http://www.zhanyict.com/en/ProductsDetail-IR-10080.htmlUsually, when boiling in water containers such as pots, the closer they are to the pot wall during heating, the higher the temperature will be. Even if PPSU has excellent heat resistance, high temperature deformation may still occur.

Excellent chemical stability, PPSU has good resistance to various chemicals, including common acids, bases, and other cleaning agents, making PPSU made water cups suitable for various environments. http://www.zhanyict.com/en/ProductsDetail-IR-10080.htmlAt the same time, PPSU's excellent resistance also ensures that dairy products stored for a long time will not experience erosion.

Good impact resistance, even in low-temperature environments, PPSU exhibits excellent impact resistance, ensuring the durability of the product. http://www.zhanyict.com/en/ProductsDetail-IR-10080.htmlPPSU itself has a certain degree of elasticity, coupled with excellent impact resistance, making it difficult for infants and children to cause damage to the water cup due to falls during use.
