PP material is not 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, and it has good comprehensive performance. The advantages of PP materials in terms of performance are reflected in solvent resistance, oil resistance, and weak acid and alkali resistance. It has advantages over other engineering plastics.
The processing temperature of PP material during production is about 180-240 degrees Celsius, and its chemical composition is still very stable at such a high temperature, so if it is made into a plastic cup, even boiling water or heating it in a microwave oven will not cause PP There is a problem of decomposition of material products. This plastic is also very stable after rainwater. The absorption rate in water is only 0.01%, and the molecular weight is between 80,000 and 150,000. Molding performance is also excellent, but shrinkage is slightly greater, and thicker-walled products made from this material tend to dent. More details please
