PP material science name is polypropylene. It is another excellent resin type developed after nylon. It is a kind of linear polymer with high density, no side chain and high crystallization. It has excellent comprehensive performance. PP has good resistance to solvents, oils, weak acids, and weak bases. Next small series for everyone to introduce PP material toxic? Is PP material toxic? PP material is polypropylene. It is a kind of resin, it is a kind of linear polymer with high density, no side chain and high crystallinity. It has very good comprehensive performance. The advantages of PP materials in terms of performance are reflected in their resistance to solvents, oils, and weak acids and bases. With other engineering plastics than the advantages. The processing temperature of PP material is about 180-240 degrees Celsius, so the chemical composition of it is still very stable under high temperature, so if it is made of plastic cup, even boiling water or high temperature heating in microwave oven will not cause PP. The decomposition of the material product is a problem. The plastic is also very stable after the rain. The absorption rate in water is only 0.01% and the molecular weight is between 8-15 million. The molding performance is also excellent, but the shrinkage rate is slightly larger. A thicker wall made from this material can easily sink. Pp material properties 1, pp material it is very good physical properties and chemical properties. Its molding performance is very good, but due to its relatively large hand-contractability, it is not yet produced for some high-precision products. By the time pp material its surface gloss is very good, and it is very easy to color. 2, pp material It has a high degree of crystallinity, and its structure is very regular, so it is a very good mechanical properties. It has very good stretchability. And it also has a very prominent performance, that is, its excellent resistance to bending fatigue, can withstand hundreds of bending will not be damaged. 3, pp material It also has a very good heat resistance, it can work at a temperature of more than one hundred degrees Celsius sterilization of the product. It can be used under very harsh environmental conditions. In addition to corrosion of concentrated sulfuric acid and concentrated nitric acid, two kinds of high-strength corrosive substances, it has very good stability for any other chemical agent. So it is very resistant to corrosion. Editor's summary: Regarding the poisonous material of PP, it is introduced here and I hope to be helpful to everyone.
