Effective Flame Retardancy: The high chlorine content in WSD CHEMICAL's CP-52 acts as an effective flame retardant by releasing non-combustible gases that dilute oxygen and form a protective char layer, significantly improving the fire resistance of PVC products.
Excellent Secondary Plasticizing Effect: Functions as an efficient secondary plasticizer, improving the flexibility and extensibility of PVC compounds. When used in combination with primary plasticizers (like DOP/DOTP from WSD CHEMICAL), it helps reduce formulation costs.
Good Lubricity & Processing Aid: Imparts internal lubrication during processing, reducing melt viscosity and improving flow properties, which can lead to smoother extrusion and calendering operations.
Low Volatility & Good Electrical Properties: Exhibits low volatility, ensuring long-term flexibility retention. It also contributes to good electrical insulation properties, making it suitable for wire and cable applications.
Cost-Effective Performance Enhancer: From WSD CHEMICAL, CP-52 offers a highly economical way to enhance both flame retardancy and flexibility, providing significant value in price-sensitive applications.
· Flexible PVC: Wire & cable insulation and sheathing, hoses, conveyor belts, flooring, and waterproof membranes.
· Rubber Products: As a flame retardant and plasticizer in certain rubber compounds.
· Coatings & Paints: Used in fire-retardant paints, adhesives, and sealants.
· Metalworking Fluids: As an extreme pressure (EP) additive in cutting oils and lubricants.
· Typical Loading: 5 - 25 phr (parts per hundred resin) in PVC formulations.
· As a Flame Retardant: 10 - 25 phr
· As a Cost-saving Secondary Plasticizer: 5 - 15 phr
· Compatibility: Compatible with most primary plasticizers and stabilizers. For optimal performance and thermal stability, it is recommended to use in conjunction with an effective heat stabilizer (e.g., calcium-zinc or lead-based stabilizers from WSD CHEMICAL).
· Packaging: Available in 250 kg drums or 1000 kg IBC totes. WSD CHEMICAL ensures secure packaging to prevent contamination and leakage.
· Storage: Store in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep containers tightly closed to prevent moisture absorption.
· Shelf Life: 24 months from the date of production when stored under recommended conditions.
· General Handling: Use with adequate ventilation. Avoid prolonged skin contact and inhalation of vapors/mists. Wear appropriate personal protective equipment (PPE) including gloves and safety glasses.
· Regulatory & Environmental: Chlorinated paraffins (particularly certain chain lengths) are subject to regional regulations (e.g., REACH, POPs). WSD CHEMICAL recommends verifying the regulatory status of CP-52 for your specific application and market. Always consult the product Safety Data Sheet (SDS) for comprehensive safety information.
