What is pp material? Is pp material toxic? PP material is also called polypropylene, which is a kind of plastic. PP material is widely used in our homes. Common PP material products in our homes include basins, barrels, furniture, films, woven bags, etc. The comprehensive performance of PP material is better than that of PE material, its light weight, good toughness, and good chemical resistance. However, the rigidity is insufficient, the weather resistance is poor, and it is easy to age, become brittle, and deform after a long period of use. In daily life, the commonly used fresh-keeping box is made of PP material.
Are PP materials toxic?
The pp material itself is non-toxic, and the products blown directly by it are generally non-toxic, but its injection, extrusion, and molded plastic products, such as pots, boxes, and shelves, contain a lot of fillers, pigments, plasticizers, and Various chemical components such as ageing agents, so some of the claimed pp material products are toxic. However, the regular tableware products we usually use all have national inspection standards and specifications, so they are non-toxic. So try to buy regular products.
pp material selection guide
1. Raw materials. PP material products are generally pp materials used, but many claimed pp materials are not pure pp, so you need to pay attention to it when buying, and food-grade PP materials that are harmless to the human body are the best.
2. Appearance. Good pp materials are generally transparent or translucent materials, with a glossy appearance, beautiful design, and no burrs, which can be seen through the appearance.
3. Durability. Heat resistance is the high-quality characteristic of pp materials. Good pp materials have very high heat resistance. They will not deform in high-temperature water and can even be sterilized in boiling water. In addition, the impact resistance of pp material is also very high-quality, it is not easy to break when pressed or impacted, and will not leave scratches.
