Polypropylene is a plastic with density from 0.90 to 0.92 g/cm³. The material is characterised by high chemical resistance (in particular, at the room temperature) to some acids, oils, water, grease, milk. It is very easy to heat but at the same time it does not conduct heat, it is non-toxic and harmless.
These features make polypropylene very popular in production of, among others, packages for sweets, cookies or pasta. Yoghurt packages, bottles, plastic plates are also made of polypropylene. It is often used in manufacturing laboratory and medical equipment- for example syringes and medicines packages
