Summary Description:Polypropylene has many excellent properties:
1. The relative density is small, only 0.89-0.91, making it one of the lighter varieties in plastic.
2. Good mechanical properties, except for impact resistance, all other mechanical properties are better than polyethylene, and the molding and processing performance is good.
3. It has high heat resistance and can be continuously used at temperatures ranging from 110 to 120 ℃.
4. Good chemical properties, almost no water absorption, and does not react with the vast majority of chemicals.
5. Pure texture and toxicity.
6. Good electrical insulation.
7. The transparency of polypropylene products is better than that of high-density polyethylene products.
It has many advantages but also disadvantages:
1. The product has poor cold resistance and low low-temperature impact strength.
2. Products are prone to aging due to the effects of light, heat, and oxygen during use.
3. Poor colorability.
4. Easy to burn.
5. Poor toughness, high static electricity, poor dyeing, printing, and adhesion.
