Polyolefins (PE and PP)

Polyolefins are a family of thermoplastics, consisting of Polyethylene (PE) and Polypropylene (PP), among other minor polymers. They are obtained mainly from petroleum and natural gas, through the polymerisation of ethylene and propylene respectively. Polyolefins generally have high chemical resistance, are transparent or translucent, and in many cases are flexible even at low temperatures. Because of their versatility, polyolefins are one of the most common plastics today.

Type of Polyolefins (PE and PP)

Polyethylen (PE)

Polyethylene is a thermoplastic of the olefin family, consisting of repeating ethylene units. Chemically, it is considered to be the polymer with the simpleststructure and is characterised by its flexibility and strength.

Polypropylene (PP)

Polypropylene is a thermoplastic polymer obtained from the polymerisation ofpropylene, a by-product of petroleum refining. It is divided into three main groups: Polypropylene copolymer, Polypropylene homopolymer and Polypropylene copolymer random. PP is the basic plastic with the lowest density, between 0.895 and 0.92 g/cm3, and is characterised by its mechanical properties, its high resistance to various acids, chemical solvents, and its dual task as a plastic and as a fibre.

Polyolefin (PO)

Polyolefin is a thermoplastic polymer obtained by the polymerisation of oleins. It is currently considered the most widely used plastic due to its great versatility.

Polypropylene homopolymer (PPH)

Polypropylene homopolymer is a polypropylene obtained from the polymerisation of pure propylene. Its high strength-to-weight ratio, good solubility and easy machinability make it the most common polypropylene. The main use of nPPH is in the chemical industry, due to its high corrosion resistance and good thermal stability.
