We all know that most plastic is easy to release carcinogens after heating, affecting human health, polypropylene, PP plastic is the best thermal resistance in the five major plastic. It is widely used in food packaging. Plastic heated by microwave oven.
Polypropylene, referred to as PP for short, is a well -performed thermoplastic synthetic resin with colorless, odorless, non -toxic, translucent solid substances, small density and light: PP is the most density plastic raw material, with a density of only 0.89 ~ 0.91g/cm (smaller than water)
Good heat resistance: In general plastics, PP plastic is the best heat resistance, and its thermal deformation temperature is 80-100 ° C. It can be cooked in boiling water
Good toughness: PP plastic has good resistance to crackedness, as well as high bending fatigue life, which is relatively easy to mold.
Chemical resistance: PP plastic can resist acid, alkali, salt solution and various organic solvents below 80 ° C, and can decompose under high temperature and oxidation effect
At the same time, PP plastic also has electrical insulation, high -intensity mechanical properties and good high -wear -resistant processing properties.
The disadvantages of PP plastic: low size accuracy, insufficient rigidity, poor weather resistance, and "copper harm". It has a post -contraction phenomenon.
As one of the five major plastic plastics, PP Plastic is widely used in daily life:
A. The field of automotive industry: PP with metal additives: pads, ventilation pipes, fans, etc.
B Home Furnishing:
C fresh -keeping box
