The difference between PVC and PP:

Firstly, PP is an environmentally friendly material, a thermoplastic resin made from propylene polymerization, with three configurations: isotactic, random, and syndiotactic. Industrial products are mainly composed of isotactic compounds. PVC material, also known as polyvinyl chloride, is one of the largest plastic products in the world in terms of production. It is inexpensive and widely used.

Secondly, the difference between PP and PVC can be clearly distinguished in both appearance and feel. PP has a relatively hard feel, while PVC is relatively soft. The best testing method is to burn these two materials with an open flame. PVC has a black dust like appearance, while PP does not. It can also be distinguished from the smell that PVC has a pungent odor, while PP has no odor.
