    Product Description

    Polyvinyl Chloride (PVC) CAS 9002-86-2 is a thermoplastic vinyl chloride homopolymer, with the repeat-unit formula (C₂H₃Cl)ₙ and EINECS 618-338-8.

    Synonyms: Poly(vinyl chloride); PVC resin; Chloroethylene polymer; Vinyl chloride polymer; Polychloroethene.

    CAS: 9002-86-2.

    Molecular formula: (C₂H₃Cl)ₙ.

    It is typically supplied as a white powder or pellets with density around 1.41 g/cm³, and is practically insoluble in water.

    The K-value is an indicator of molecular weight and degree of polymerization; K65-68 corresponds to a medium molecular weight suspension grade, often classified as SG-5.

    This rigid or unplasticized grade is widely used for PVC pipes and fittings, window profiles, door frames, siding, cladding, electrical conduit and other structural profiles.

    The resin can be compounded with stabilizers, impact modifiers, lubricants and fillers to meet the required processing and end-use properties.

    It can be formulated with plasticizers to produce flexible, flame-retardant insulating sheaths for industrial wiring and power cables.

    The typical purity (resin content) is about 99.5% or higher, with a K-value of 65-68 and apparent density about 0.45-0.55 g/cm³.

    The viscosity number is about 105-118 ml/g, with residual vinyl chloride monomer (VCM) not more than 1.0 ppm.

    PVC begins to decompose above about 200 °C, releasing corrosive hydrogen chloride gas, so processing temperatures should be controlled.

    Store in a cool, dry, ventilated area away from moisture, direct sunlight and heat sources above about 35 °C, and control dust.

    Protect from heat and moisture, and keep containers closed when not in use.

    Confirm appearance, purity, K-value, apparent density, volatile matter, viscosity number, residual VCM and grade as required.

    Use suitable eye and skin protection during handling, and wash skin contact with soap and water.

    Confirm packaging with the requested quantity and destination requirements.

    FAQ - Technical & Supply Chain

    • Q:

      What is Polyvinyl Chloride CAS 9002-86-2?

      A: Polyvinyl Chloride, commonly called PVC, is a thermoplastic vinyl chloride homopolymer with CAS 9002-86-2 and general formula (C2H3Cl)n. It is typically supplied as a white powder or pellets with density around 1.41 g/cm3 and is practically insoluble in water.
    • Q:

      What does the K-value 65-68 mean for this PVC resin?

      A: K-value is an indicator of molecular weight and degree of polymerization. A K65-68 range corresponds to a medium molecular weight suspension grade, often classified as SG-5, and provides a practical balance of mechanical strength and melt processability for rigid extrusion.
    • Q:

      Which industrial applications are best suited to Polyvinyl Chloride CAS 9002-86-2?

      A: This rigid or unplasticized grade is widely used for PVC pipes and fittings, window profiles, door frames, siding, cladding, electrical conduit, and other structural profiles. The resin can be compounded with stabilizers, impact modifiers, lubricants, and fillers to meet the required processing and end-use properties.
    • Q:

      How should PVC resin be stored and processed to avoid degradation?

      A: Store PVC resin in a cool, dry, ventilated area away from moisture, direct sunlight, and heat sources above about 35 degrees C, and control dust to avoid combustible dust clouds. During processing, temperatures should be controlled because PVC begins to decompose above about 200 degrees C, releasing corrosive hydrogen chloride gas.
