Yes, there are different grades of PVC, each with different properties depending on the intended application.
PVC can be formulated in various ways depending on its intended use. Some grades are flexible due to the addition of plasticisers, while others (such as uPVC) are unplasticised and more rigid. Additives can also influence UV resistance, impact strength and other material characteristics. At MKM Extrusions, our range of stock profiles are manufactured mainly in rigid PVC, with some selected profiles available in flexible PVC. The rigid profiles are produced using external grade rigid PVC, suitable for both indoor and outdoor use.
