Description

Polypropylene PP is a semi-crystalline material. It is deeper than PE and has a higher melting point. Since the homogeneous PP sheet becomes brittle and easy to break when the temperature is lower than 0℃, many commercial PP sheets add 1~4% ethylene raw material to improve the flexibility of the sheet.

The strength of polypropylene PP increases with the increase of ethylene content. The melting point temperature of polypropylene is 150°C. Due to the increased crystallinity, the board surface and scratch-resistance of this material are very good. PP board is usually used in a corrosion-resistant environment, and the PP is improved by adding glass fiber, metal additives, or thermoplastic rubber.

Advantages of PP solid plastic board:

1. Chemical inertness: PP is a chemically inert material with excellent corrosion resistance, can be used stably for a long time in many chemical environments, and is not easily corroded and eroded by chemical substances.
2. High temperature resistance: PP solid plastic sheet can work at relatively high temperature and has excellent heat resistance. This makes it perform well in some applications that require resistance to high temperature environments, such as hot air ducts, high temperature industrial equipment, etc.
3. Good mechanical properties: PP solid plastic sheet has high strength and rigidity while having low density. This makes it a lightweight yet strong enough choice in many structural and mechanical applications.
4. Electrical insulation: Due to its good electrical insulation properties, PP solid plastic sheets are widely used in the electronics and electrical fields, such as making battery isolation plates, electrical components, etc.
5. Good impact toughness: PP solid plastic sheet has good impact resistance and can perform well in applications that require durability and shock resistance.
6. Ease of processing: PP solid plastic sheet can be cut, welded, bent, formed, etc. through various processing methods, and has good processing performance, making it suitable for a variety of customization needs.
7. Environmentally friendly: PP is a recyclable plastic material with low environmental impact. It can replace other materials in some environmentally conscious applications.
8. Anti-ultraviolet performance: PP solid plastic sheet has good anti-ultraviolet performance and is not easily affected by ultraviolet radiation, so it can also maintain a long service life in outdoor applications.

It should be noted that although PP solid plastic sheet has many advantages, in specific applications, its limitations also need to be considered, such as the toughness at low temperatures may be reduced, and it may not be suitable for certain chemicals. When selecting materials, various factors should be considered comprehensively according to specific application requirements.
