PVC materials are more commonly used in life and have a wide range of applications.
The difference between PP and PVC.
PP (polypropylene) is a thermoplastic polymer that is lightweight, strong, and flexible. It is resistant to many chemicals and has a high melting point. PVC (polyvinyl chloride) is a type of plastic that is rigid and durable. It is also resistant to many chemicals, but it has a lower melting point than PP.
PP is an environmentally friendly material, a thermoplastic resin made from the polymerization of propylene, with three configurations: isotonic, irregular and inter-regular, and industrial products with isotonic as the main component. pvc material, namely polyvinyl chloride, is one of the world’s largest plastic products in terms of production, cheap and widely used.
The difference between PP and PVC is obvious from the appearance and feel of PP, which is hard to the touch, and PVC, which is relatively soft. The best way to test is to burn the two materials with an open flame, there is a black dusty PVC, while PP is not. From the smell can also be distinguished, PVC has a choking smell, while PP is not.
Overall, the main difference between PP and PVC is their chemical structure, physical properties, and applications. PP is a versatile material that is suitable for a wide range of applications, while PVC is a tough and rigid material that is commonly used in construction and industrial applications.
