Polypropylene, abbreviated as PP, is a polymer made by the polymerization reaction of propylene, a thermoplastic synthetic resin with excellent performance and a translucent solid substance. It is commonly used in the manufacture of food contact materials such as food containers, bottle caps and food packaging films.
1、Small relative density, only 0.89-0.91, is one of the lightest varieties of plastics.
2, good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, molding and processing performance.
3, has high heat resistance, continuous use temperature up to 110-120 ℃.
4, good chemical properties of corrosion resistance, almost no water absorption, and most chemicals do not react.
5、Pure texture, non-toxic.
6、Good electrical insulation.
7、Transparency of polypropylene products is better than that of HDPE products.
1、The products have poor cold resistance and low impact strength at low temperature.
2、The products are easily aged by light, heat and oxygen in use.
3、The coloring is not good.
4, easy to burn.
5, bad toughness, high static electricity, poor dyeing, printing and adhesion.
