It is well known that PVC is a kind of low temperature brittle material, and its low temperature performance is an important index in the inspection of PVC-U profile​. In this passage, the low-temperature properties of PVC-U profiles are mainly reflected by the low-temperature drop hammer of profiles, and analyzed from the wall thickness and cross-section structure of profiles, the degree of plasticization of profiles and the CPE content of profiles.
