What is the raw material for making milk tea cups?

Generally, the raw material for making milk tea cups is polypropylene (PP for short), which is a thermoplastic resin made by polymerization of propylene and is the main raw material for producing plastic milk tea cups. According to the position of methyl groups are divided into isotactic polypropylene, atactic polypropylene and intertactic polypropylene.

Copolymer PP material has a lower thermal deformation temperature (100℃), low transparency, low gloss, low rigidity, but has a stronger impact strength, the impact strength of PP increases with the increase of ethylene content. The veka softening temperature of PP is 150℃. The material has good surface stiffness and scratch resistance due to its high crystallinity. There is no environmental stress cracking problem in PP.

Polypropylene has many excellent properties:

1, the relative density is small, only 0.89-0.91, is one of the lightest varieties of plastic.

2, good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, good molding performance.

3, with high heat resistance, continuous use temperature up to 110-120℃.

4, good chemical properties, almost no water, and the vast majority of chemicals do not react.

5, pure texture, non-toxic.

6, good electrical insulation.

7. The transparency of polypropylene products is better than that of high-density polyethylene products.
