Features Of Wacker VINNOL H 40/50 Chlorine Vinyl Copolymer Resin

  1. High chlorine content (approx. 40–50 wt%) for enhanced flame retardancy and chemical resistance.

  2. Excellent thermal stability suitable for processing at elevated temperatures without premature degradation.

  3. Good compatibility with plasticizers, stabilizers, and other PVC-based resins for versatile formulation design.

  4. Consistent particle morphology and narrow particle size distribution ensuring uniform dispersion and processing reliability.

  5. Low residual vinyl chloride monomer (VCM) content, meeting stringent regulatory requirements for safe handling and end-use compliance.

Typical Applications Of Wacker VINNOL H 40/50 Chlorine Vinyl Copolymer Resin

  1. Flame-retardant wire and cable insulation for building and transportation infrastructure.

  2. Heavy-duty industrial flooring and resilient sheeting requiring chemical and abrasion resistance.

  3. Coated fabrics for technical textiles, including tarpaulins, inflatable structures, and protective covers.

  4. Extruded profiles and rigid sheets for chemical storage tanks and corrosion-resistant linings.

  5. Specialty adhesives and sealants where high polarity and substrate adhesion are critical.
