UPVC is polyvinyl chloride. It is a raw material, usually polyvinyl chloride resin powder. Light PVC can't make anything. To create useful things, various active agents or catalyst stabilizers must be added. UPVC is a semi-finished product after adding a certain active agent ( It’s still in powder form).
