Product Name:Polyvinyl chloride
English Name:Polyvinyl chloride
CAS No.:93050-82-9
Aliases:PVC, Poly(vinyl chloride)
Molecular Formula:H(CH2CHCl)nH
Physical Properties:White or light yellow powder or granular particles, odorless and tasteless, density approximately 1.35-1.45 g/cm³, insoluble in water, soluble in organic solvents such as cyclohexanone and tetrahydrofuran, good chemical stability and electrical insulation, poor thermal and light stability, begins to decompose releasing hydrogen chloride when heated above 130°C.
Uses:Polyvinyl chloride is a widely used thermoplastic polymer, mainly used in the production of pipes and fittings, wire and cable insulation, building doors and window profiles, artificial leather, films, sheets, and packaging materials. It is also extensively applied in chemical anti-corrosion equipment, automotive parts, and daily consumer goods, and its flexibility can be adjusted by adding plasticizers to meet different processing requirements.
Technical Specifications:
Appearance is white or light yellow powder or granules with uniform particle size and no mechanical impurities.
Density ranges from 1.35 to 1.45 g/cm³, with bulk density of 0.40-0.60 g/cm³.
Thermal decomposition temperature is above 130°C, softening point is 75-85°C, long-term service temperature is -15 to 60°C.
Tensile strength is no less than 40 MPa, elongation at break is no less than 80%, and notched impact strength is no less than 5 kJ/m².
Volume resistivity is no less than 1.0×10¹⁴ Ω·cm, and dielectric strength is no less than 20 kV/mm.
