Polypropylene is a thermoplastic polymer resin of the composition of C3H6. It is a commonly used household and industrial plastic which is available in fiber-form or hardened plastic form. The versatility of forms and applications has made it one of the most widely used plastics today. The fact that it is recyclable and is being recycled in battery cases, paint cans, home storage, etc. makes it very popular.
Polypropylene due to its flexibility, occurs in two forms:
Polypropylene has favourable chemical characteristics as compared to other plastics, with a high melting point of 160 degrees Celsius, which makes it useful for long-term durability of plastic food containers. It has zero levels of the toxic component - Bisphenol (BPA), which makes it ideal for food packaging. It is chemically very resistant.
· Some of the important physical features, include:
· Water resistant
· Easily customisable
· Though less sturdy than polyethylene, it is still damage-resistant
· Very flexible
· Good fatigue resistance
· Heat resistant
Specifically due to its higher melting point, Polypropylene has gained greater popularity than Polyethylene. Polypropylene is highly versatile and can be customised to make different things. Manufacturers can also add dye and colour to it without degrading the quality of the plastic. Being lightweight, inexpensive and non-toxic, it is often used in things people need every day.
