Chemical and physical properties:
The crystal structure of the most common commercial polypropylene is somewhere between low density polyethylene (LDPE) and high density polyethylene (HDPE). Young's modulus (modulus of elasticity) is also moderate. However, it is less hard than LDPE and much less brittle than HDPE. This allows polypropylene to be used as a substitute for engineering plastics such as ABS.
Polypropylene shows very good resistance to fatigue. It is low cost, has good impact resistance. It has a low coefficient of friction and provides very good electrical insulation. Chemical resistance is good. It is suitable for all thermoplastic processing processes. The melting temperature of polypropylene is around 160 degrees Celsius.
However, it has the following disadvantages. It has low resistance to UV rays and shows high thermal expansion. It is difficult to paint and coat. It has low resistance to external weather conditions and is open to oxidation. It is flammable and interacts with solvents containing chlorine.
Materials such as detergent box covers, margarine containers are produced from this type of material. By recycling, synthetic carpet base, various plastic toys, stationery materials and similar products can be produced.
