Is polypropylene material toxic when cooking?
pp即：聚丙烯，聚丙烯材质的饭盒只要在规定的温度范围内，是没有毒的，可放心使用的。 聚丙烯无毒、无味，密度小，强度、刚度、硬度耐热性均优于低压聚乙烯,可在100℃左右使用。聚丙烯具有良好的介电性能和高频绝缘性且不受湿度影响，但低温时变脆，不耐磨、易老化。聚丙烯适于制作一般机械零件、耐腐蚀零件和绝缘零件。常见的酸、碱等有机溶剂对它几乎不起作用，可用于食具。
PP means polypropylene. Polypropylene lunch boxes are non-toxic and can be used with confidence as long as they are within the specified temperature range. Polypropylene is non-toxic, odorless, with low density, and superior strength, stiffness, hardness, and heat resistance to low-pressure polyethylene. It can be used at around 100 ℃. Polypropylene has good dielectric properties and high-frequency insulation, and is not affected by humidity. However, it becomes brittle at low temperatures, is not wear-resistant, and is prone to aging. Polypropylene is suitable for making general mechanical parts, corrosion-resistant parts, and insulation parts. Common organic solvents such as acids and bases have little effect on it and can be used in tableware.
聚丙烯为无毒、无臭、无味的乳白色高结晶的聚合物，密度只有0. 90--"0. 91g/cm3，是目前所有塑料中最轻的品种之一。
Polypropylene is a non-toxic, odorless, and tasteless milky white high crystalline polymer with a density of only 0 90- "0.91g/cm3, is currently one of the lightest varieties among all plastics.
