UPVC and PVC-U are the same material. Refers to PVC without plasticizers. Plasticizers are added to PVC to facilitate processing and increase flexibility. Generally, less than 15 parts are rigid PVC. Therefore, PVC without plasticizers also belongs to rigid PVC.
PVC-u is also called UPVC (hard polyvinyl chloride), U means adding plasticizer, the chlorine of PVC-u will not be released. The differences between PVC-U and PVC, which are mostly used for domestic drainage, are as follows:
Upvc and pvc are made of the same material and have the same use.
The original text of u in upvc is "unplasticized". The PVC raw material that is not added with "plasticizer" is called UPVC or PVCU. Without the addition of "plasticizer", all the chlorine (Cl) in the PVC raw material will be volatilized, while the PVC raw material added with "plasticizer" will have a lot of residual chlorine (Cl) that cannot be volatilized.
There is no residual chlorine released from the water pipes of upvc. There will be residual chlorine released from the pvc water pipe.
