Polypropylene

Introduction:

Polypropylene is a polymer made from addition of many propylene monomers. It has good resistant capacity to many acids, bases and chemical solvents. Its melting point is 160 °C (320 °F) so it is used in plastic materials for medical laboratories as an autoclave. Thin sheets of polypropylene are also used in dielectrics. Some properties of Polypropylene are given below:

Properties:

• Thermoplastic property
• Good strength
• Good environmental resistance
• Low density, hence light weight
• Good toughness
• Ability to be remoulded
