Available in medium-chain (CP52, ~52% chlorine) and high-chain (CP70, ~70% chlorine) grades, CPW provides cost-effective plasticiser extension and flame retardancy in PVC cable compounds, flooring, and industrial rubber goods — reducing formulation cost vs primary phthalate plasticisers while adding fire resistance.

Applications
- Secondary PVC Plasticiser — Cost Reduction — CPW is used at 20–40% replacement of primary phthalate (DINP/DEHP) in flexible PVC compounds — reducing formulation cost while maintaining acceptable flexibility.
- Flame Retardant Additive in PVC Cables — CP70 (high chlorine content) provides flame retardancy to PVC cable insulation and jacketing — the chlorine content acts as a halogen-based flame retardant, slowing flame spread in electrical cable applications critical for UAE and Saudi Arabia building codes.
- Metalworking & Cutting Fluid Additive — CP52 is used as an extreme pressure (EP) additive in metalworking cutting fluids, gear oils, and industrial lubricants — the active chlorine provides lubricity under high-pressure metal cutting conditions in UAE manufacturing.
- Rubber & Sealant Formulations — Used as a plasticiser and processing aid in natural and synthetic rubber compounds and polysulphide sealants for construction and industrial applications.
- Waterproofing & Bituminous Coatings — Added to bituminous and solvent-based waterproofing coatings to improve flexibility and reduce cost — used in construction waterproofing applications across UAE and Saudi Arabia.
Key properties
- Cost-effective secondary plasticiser — reduces phthalate requirement
- Built-in flame retardancy from chlorine content
- Good compatibility with DINP, DOP, and NBR rubber
- High density contributes to PVC compound specific gravity
- Low volatility — good permanence in service
- CP52: liquid — easy handling and dosing
- CP70: solid/waxy — higher flame retardancy, used in cable compounds
- Broad compatibility with PVC stabiliser systems
Usage and recommendations
Secondary plasticiser replacement: substitute 15–35% of DINP with CP52 (w/w of total plasticiser) in cost-optimised PVC compounds. Exceeding 35% substitution may reduce electrical properties and increase compound viscosity. For flame-retardant cable jackets: use CP70 at 10–20 phr with DINP main plasticiser and Ca-Zn stabiliser. Regulatory note: Short-chain chlorinated paraffins (SCCP, C10-13) are listed as POPs under the Stockholm Convention and restricted. Raykem supplies only medium-chain (CP52, C14-17) and long-chain (CP70, C18-30) grades which are not restricted — ensure compliance with applicable regulations.
Packaging
- 200 kg Steel Drums
- IBC 950–1,000 kg (CP52 liquid only)
- Custom packaging on request
Storage and shelf life
Store in sealed drums at 5–40°C. CP52 is a viscous liquid — may require warming (40°C) to improve pourability in winter. CP70 is semi-solid — store above 20°C to facilitate handling. Flash point > 200°C — standard storage. Shelf life: 24 months.
