Performance advantages of PP foam material

Polypropylene foam has many advantages:

1. The rigidity of polypropylene (PP) is significantly better than that of polyethylene (PE). The flexural modulus of PP is about 1.52Gpa, and that of PE is only 207Mpa. Its compressive strength is higher than soft PUR and PE.

2. The glass transition temperature of polypropylene is lower than room temperature, the impact resistance is better than that of PS, and compared with the recyclability of PS foam, polypropylene foam is an environmentally friendly material.

3. Polypropylene has a high heat distortion temperature and can be used in some high-temperature fields. Foamed polypropylene can usually withstand high temperatures of 120 °C, which is much higher than polyethylene foam, and is widely used in many fields such as food and automobiles.

4. Good low-temperature properties: The product exhibits good performance even at -30°C.

5. Energy absorption: PP foam products have good energy absorption properties, excellent compression resistance and energy absorption performance, and are widely used in automobile bumper energy treatment systems and other anti-collision energy-absorbing components, and also have good sound absorption and shock absorption.

6. Dimensional shape recovery stability: PP foamed products will quickly return to their original shape without Polypropylene resin has the characteristics of light weight, abundant raw material sources, superior cost performance, excellent heat resistance, chemical resistance, and easy recycling. It is the fastest-growing general-purpose thermoplastic resin in the world. The research and development of the foam has always been a technical hotspot and difficulty in the industry. At present, some developed countries are vigorously developing it as the next-generation green foam material to replace the above three kinds of foams. Among them, polypropylene expanded beads (EPP), foamed sheets and plates are the most typical and the most used varieties.

At present, there are more than 70 PP resin manufacturers in China, with more than 100 sets of various devices, and the production capacity exceeds 5 million tons/year.
