Polyvinyl chloride
Polyvinyl chloride (PVC) is a widely used thermoplastic polymer made from the monomer vinyl chloride. It is known for its versatility, resistance to chemical influences, and good mechanical properties. PVC is used in a wide range of industrial and everyday applications, including construction, electronics, medicine, and packaging.
Physical and chemical properties
Polyvinyl chloride exhibits several remarkable physical and chemical properties:
-
Versatility: PVC can be produced in different forms, such as rigid (uPVC) and flexible PVC, making it suitable for various applications.
-
Chemical resistance: PVC is resistant to many chemicals, including acids, alkalis, and salts.
-
Moisture resistance: PVC is water-repellent and commonly used in waterproof applications.
-
Good mechanical properties: PVC has high tensile strength and resistance to abrasion and wear.
-
Electrical insulation: PVC has excellent electrical insulating properties and is widely used in cable sheathing.
-
Durability: PVC is long-lasting and resistant to environmental conditions, extending its service life.
