What difference between PP and PVC? |
| PP | PVC |
Full Name | Polypropylene | Polyvinyl Chloride |
Chemical Structure | thermoplastic resin polymerized from propylene monomers, known for its high heat resistance, chemical resistance, and strength | thermoplastic resin polymerized from vinyl chloride monomers, and its products may contain plasticizers and other additives. |
Physical Properties | low density (around 0.90–0.91 g/cm³) | higher density (around 1.4 g/cm³) |
good electrical properties | good tensile |
high-frequency insulation | compressive strength |
become brittle at low temperatures | less flexible |
| has poor heat resistance. |
Application Fields | automotive | construction |
home appliances | artificial leather |
medical devices | corrosion-resistant pipes |
acid and alkali-resistant equipment | centrifugal pumps |
environmental protection equipment | blowers |
wastewater and exhaust gas discharge systems | oil pipelines |
