What’s the difference between UPVC and PVC?

UPVC (Unplasticized Polyvinyl Chloride, PVCu) is a rigid material that can be used for thermoplastic extrusion and is supplied complexly clear or in a variety of colours and strengths.


Unplasticised PVC is one of the stiffest polymers at ambient temperatures and is very durable. It is extremely versatile and can be used for UPVC profiles for internal and external applications, such as window frames, fence posts, trims, pipes, cores, cladding, and trunking.

PVC (Polyvinyl Chloride) has plasticizers added to make the product more flexible. Flexible PVC is a thermoplastic extrusion polymer used in a wide variety of plastic profiles. It can be very lightweight and is available in various softnesses, grades and a wide range of colours. It is very resilient and is compatible with many additives for colour, UV stabilization, and flame retardants. It is used for sleeves, gaskets trims and hosing, seals, handrails, decking products, wire, and cable insulation to name but a few.
