With the development of society, more and more plastic products around us have become the main materials in the 21st century. ABS plastics and PP plastics are the most common. What is the difference between them
　　By comparison, the results are as follows

　　1. Density
　　PP has the lowest density among all synthetic resins, only 0.90-0.91g/cm3, which is about 60% of PVC density. This means that more products of the same volume can be produced with the same weight of raw materials.
　　2. Mechanical properties
　　The tensile strength and rigidity of PP are good, but the impact strength is poor, especially at low temperature. In addition, if there is orientation or stress in the molding process, the impact strength will be significantly reduced. Although the impact strength is poor, its mechanical properties can compete with high cost engineering plastics in many fields after filling or strengthening.
　　3. Surface hardness
　　The surface hardness of PP is lower than that of PE. When the crystallinity is high, the hardness also increases, but it is still lower than PVC, PS, ABS and so on.
　　4. Thermal properties
　　Compared with ABS, the heat resistance of PP is better.
　　ABS plastics and PP plastics performance characteristics are different, to say which is good and which is not really a final conclusion, only specific to the production of which products can have which material is more suitable.
