What is pp material?

PP material is actually a polymer formed by addition polymerization of propylene (also known as polypropylene).

1. PP material is a thermoplastic synthetic resin with excellent performance. It is a colorless, tasteless, non-toxic and translucent thermoplastic lightweight general-purpose plastic.

2. PP material has excellent chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good wear-resistant processing performance, and is widely used in machinery, automobile, electronics, architecture and other industries, textiles, food, etc

3. PP material has extremely high plasticity, strength and toughness and high wear resistance, so it gradually replaces many products, such as wood and metal materials. Because of its good graft and composite functions, it has also been widely used in concrete, textiles, packaging, agriculture, forestry and fishery.

4. In architectural decoration, pp materials are also widely used, usually in the form of pipes and boards.

First of all, PP is an environment-friendly material. It is a thermoplastic resin obtained by polymerization of propylene. It has three configurations: uniform, random and identical. Industrial products are mainly composed of identical structures. PVC material is PVC. It is one of the most productive plastic products in the world. It is cheap and widely used.

Is pp material resistant to high temperature?

PP water cup can withstand high temperature. Under normal conditions, the maximum heating temperature is 120-150 ℃, and the embrittlement temperature is – 35 ℃. Generally speaking, the boiling water temperature is 100 ℃, and the heating temperature of pp material water cup is much higher. It is at boiling temperature, so when using pp material, you don’t have to worry that it can’t withstand high temperature and dare not put hot water into the pp cup.

5、 Addition of polyethylene

Polyethylene is also a kind of plastic with high crystallinity, and the molding shrinkage is also very large. However, after adding polypropylene, the crystallinity of each other is destroyed to varying degrees, which reduces the overall molding shrinkage.

6、 Change of MI (melt index) of PP plastics

The molding shrinkage of polypropylene is affected by its crystallinity, which is also affected by its molecular weight. When MI increases, the molecular weight decreases, the crystallization rate increases, and the molding shrinkage increases. The change of MI of polypropylene also has certain influence on the molding shrinkage.
