What is Polypropylene?
Polypropylene is a thermoplastic polymer which is both tough and durable. Made from the polymerization of propylene gas in the presence of a catalyst system it is becoming increasing popular, even replacing more traditional materials such as wood or metal.
It is inexpensive to make and can be produced in a variety of weights and forms. An extremely versatile material it is suitable for use in a wide range of applications and industries.
What are the Main Properties of Polypropylene?
Polypropylene is lightweight and flexible but can also be produced in a semi-rigid form. In its raw form it is translucent but can be coloured. It has a tough material with good chemical resistance. It has good fatigue resistance, integral heat resistance and heat resistance.
Apart from the above characteristics, polypropylene (PP) has excellent electrical and chemical resistance at higher temperatures. Other benefits of polypropylene are that it doesn’t deteriorate in the presence of bacteria or absorb water and so is ideal for use in locations requiring a sterile environment.
Where is Polypropylene Used?
Polypropylene is very versatile and as it can be made in different forms is suitable for use in many different applications. As it doesn’t contain BPA (bisphenol A) it is safe for use with both children and a food product so is used extensively for the food packaging.
It is also used extensively in the textile industry for the production of garments and household furnishings as well as carpets. Since it isn’t affected by bacteria it is used widely in medical applications.
It has a low level of electrical conductivity which means that it can be used effectively in electronic products and it is also used on the construction industry. In fact, it is really quite amazing how many ways in which polypropylene can be used!
