PP (Polypropyleen)

PP (Polypropylene)

Plastic

Polypropylene (PP) is a versatile and chemically resistant plastic widely used in the technical industry. The material is lightweight, tough, easy to process, and offers excellent chemical and electrical properties. Thanks to its good balance between stiffness and flexibility, PP is widely applied in both structural and protective applications.
Well-known trade names for PP include Hostalen®, Moplen®, Daplen®, and Novolen®. These grades are often used in mechanical engineering, chemical industry, water treatment, and the food industry.

Frequently Asked Questions about PP (Polypropylene)

What are the main advantages of PP?

PP is lightweight, tough, chemically resistant, easy to machine, and food-safe—combining performance with low cost.

Is PP suitable for food contact?

Yes, many PP grades are FDA- and EU-compliant and widely used in the food industry.

How resistant is PP to chemicals?

PP has excellent resistance to acids, alkalis, solvents, and salts, making it a staple in chemical processing equipment.

Is PP weldable?

Absolutely, PP welds very well with hot-air or mirror welding, ideal for custom fabrications.

Can PP be laser-cut?

Technically yes, but in practice milling or sawing is more common due to PP’s low laser absorption.

Is PP UV-resistant?

Standard PP has limited UV resistance; for outdoor use, carbon-black filled or UV-stabilized grades are recommended.

How does PP compare to PE?

PP is stiffer and more heat-resistant than PE, but slightly less impact-resistant at low temperatures.

What are alternatives to PP for higher mechanical demands?

For greater stiffness or dimensional stability, consider materials like POM or PA (nylon).
