What kind of material is pp? Many people should not know much about it. In fact, the products made of pp materials in our lives are everywhere. Just like many other materials, there are many materials that we are not familiar with in people's daily life. Use, careful friends may find that many tea cups, crisper and cup bottom are marked with PP, then what is pp material?

The Chinese name of the PP material is polypropylene, the English name is polypropylene, the former P stands for poly-"multiple, polymerization", and the latter P stands for propylene "propylene". Temperature resistant -20 - 120 degrees, is one of the common microwave plastics.

Pp is engineering plastics, which is the abbreviation of Polypropylene. Pp also has a Chinese name, called polypropylene. According to chemical composition, pp is a crystalline isotactic polymer in which molecular chain links are well aligned. It is also divided into isotactic PP (polypropylene) and random PP. As its name suggests, isotactic pp is a thermoplastic resin with a crystallinity of more than 95 and a molecular weight of between 8 and 150,000. Propylene is a non-crystalline, slightly viscous white wax at room temperature with a low molecular weight. Commonly known as space glass. Non-toxic, tasteless, strength, stiffness, heat resistance are better, can be used about 130 degrees, have better electrical properties, low moisture absorption, good fluidity, extremely corrosion-resistant, can be used for food utensils.

Pp material for pp tea cup, disposable cup custom, pp tea cup cover, automotive industry (mainly using PP with metal additives: fenders, ventilation pipes, fans, etc.), instruments (dishwasher door liner, dry Machine ventilation pipes, washing machine frames and covers, refrigerator door liners, etc.), consumer goods (turf and garden equipment such as lawn mowers and sprinklers, etc.).

Tips: Qualified PP material can be placed in the microwave oven, but the heating time should not be too long.
