The properties of polypropylene (PP) lend themselves to a number of industries. The plastic’s excellent chemical resistance and very high melting point (around 20°F) means it can stand up to steam sterilisation methods for effective decontamination of germs, fungi and parasites. This makes it an ideal choice for medical applications, medical devices, the food container industry and those that need a heat resistant application.
PP is used throughout the automotive industry for car dashboards, bumpers, cladding and exterior trims and internal elements due to its lightweight and flexible qualities.
In packaging, there are a wide range of applications, some that you may not realise. In its flexible form it has replaced cellophane, metals and paper due to its lower price and superior properties. So you will find it as film and flexible packaging of tobacco, clothing, food and confectionery.
Another element of the materials properties is its ability to keep perspiration away from the skin. It has therefore been added to cold weather base layers for winter sports, and warm weather options for summer activities.
In rigid form, PP is used in caps and closures, pallets, crates, bottles and jars for packaging toiletries and cleaning products for example. It is also used for thin-wall containers such as yoghurt pots and disposable hot drinks cups.
