Yes, uPVC is a type of plastic. It stands for unplasticised polyvinyl chloride and is known for its rigid characteristics.
uPVC is a version of PVC that contains no added plasticisers. This results in a material that is generally more rigid compared to flexible PVC, though thinner profiles may still offer some degree of flexibility. At MKM Extrusions, uPVC is used manufacturing the stock range of rigid plastic profiles, including angle trims, flat strips, and channels. It offers a durable solution for many indoor and outdoor applications. There are different types of uPVC depending on the formulation.
