The differences between UPVC and PVC profiles in terms of physical properties

• UPVC: Due to the absence of plasticizers, UPVC usually exhibits hard characteristics and possesses high rigidity and strength. Meanwhile, the melt viscosity of UPVC is high and its fluidity is poor, making the processing relatively challenging.

• PVC: Depending on the amount of plasticizer added, PVC can take on various forms such as soft, semi-rigid and hard. The addition of plasticizer makes PVC softer, more flexible and easier to process.
