Pp material is actually a polymer formed by addition polymerization of propylene, also called polypropylene. It is a kind of thermoplastic synthetic resin with excellent performance, and it is a colorless, odorless, nontoxic and translucent thermoplastic lightweight general plastic. In building decoration, pp materials are also widely used, generally in the form of pipes and plates.
Pp material has excellent chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good wear-resistant processing performance, and is widely used in all walks of life, such as machinery, automobiles, electronic appliances, construction, textiles, food and so on.
Pp material has high plasticity, strong toughness and high wear resistance, so it gradually replaces many products, such as wood and metal. Because of its good grafting and composite function, it is also widely used in concrete, textile, packaging, agriculture, forestry and fishery.
Which material is better, pp or pvc?
PP is an environmentally friendly material. It is a thermoplastic resin prepared by propylene polymerization. It has three configurations: isotactic, random and syndiotactic. Industrial products are mainly composed of isotactic structures. The PVC material is polyvinyl chloride. It is one of the most productive plastic products in the world. It is cheap and widely used.
The difference between PP and PVC can be clearly distinguished in appearance and feel. PP feels hard and PVC is soft. The best test method is to burn these two materials under an open flame. Black powder is PVC, PP is not. You can tell from the smell. PVC has a taste, but PP has no taste.
