Polypropylene

What is polypropylene and where is it used?

PolypropylenePolypropylene is a thermoplastic polymer – an incredibly versatile plastic that can be used in a variety of settings. The material is made through the polymerisation of propene, or propylene, which is the most commercially versatile thermoplastic polymer.

Polypropylene has good chemical resistance, and is tough and durable. Due to its many qualities, polypropylene is extremely versatile. When moulded, it is known to be used for automotive components and sailing dinghies, as well as building and roofing products.

Why is polypropylene ideal for roofing products?

Polypropylene is an excellent roofing material, not only due to the aforementioned benefits, but also because it is thermally stabilised, UV-resistant, acid rain-resistant and has a non-reflective surface. UV stability prevents colour fade and brittleness.

The material has a high melting point and does not deteriorate in the presence of bacteria. It is also easy to modify the composition of the finished products to best suit their application through the use of special additives, and to add different coloured pigments for consistent appearance; this enables manufacturers like Hambleside Danelaw to supply the appropriate colours to suit the products. Being lightweight and flexible, polypropylene is an ideal material for roofing products.

Uses of polypropylene in pitched roofing

Polypropylene is used across the construction industry for roofing and building products. It is used in roofing sheets and insulation as well as being moulded to form roofing products. It is the material of choice for our Interlocking Dry Verge, tile roof vents, slate roof vents and many other roofing products.

Environmental benefits

Polypropylene’s non-toxic qualities make it suitable for everyday use, including in grey water harvesting systems, while keeping its environmental impact to a minimum. It is fully recyclable at the end of its service life and benefits from having a low density and a lower volume of absolute waste during production. As a responsible manufacturer, we continually strive to reduce our waste and increase our environmental qualities. We take sustainability very seriously, and work by the British standard associated with environmental standards: BS EN ISO 14001:2015 Environmental management systems.
