POLYPROPYLENE PROS AND CONS
Polypropylene, like every other polymer, has advantages and disadvantages that make it more suitable for certain uses than others.
Advantages of polypropylene:
It is a relatively inexpensive material
It possesses high flexural strength because of its semi-crystalline nature
It has a low coefficient of friction
It is very resistant to moisture
It has good chemical resistance over a wide range of bases and acids
It possesses good fatigue resistance
It has good impact strength
It has a good resistance to electricity and is thus a good electrical insulator
It is more easily repaired from damage
Disadvantages of polypropylene:
It has a high thermal expansion coefficient which limits its high temperature applications
It is susceptible to UV degradation
It has poor resistance to chlorinated solvents and aromatics
It is known to be difficult to paint as it has poor bonding properties
It has a high flammability
It is susceptible to oxidation
Despite its shortcomings, polypropylene is a great material. It has a unique blend of qualities that aren’t found in any other material, which makes it an ideal choice for many projects.
