Description

Polypropylene, Chlorinated is a chemically modified polymer where chlorine atoms are introduced onto the polypropylene backbone, significantly altering its properties. This modification enhances its flame retardancy, chemical resistance, and compatibility with other polymers, making it a valuable additive and base material. It is primarily sought after by manufacturers in the plastics, coatings, and adhesives industries seeking to improve material performance and meet specific regulatory requirements.

Application

• As a flame retardant and smoke suppressant additive in polyolefin compounds, PVC, and various thermoplastic elastomers.
• As a secondary plasticizer and compatibility enhancer in PVC formulations, improving low-temperature flexibility and extrusion properties.
• As a base resin or modifier in the production of adhesives, sealants, and caulks, providing improved adhesion and water resistance.
• In the formulation of protective coatings and paints, where it contributes to chemical and moisture resistance.
• As a viscosity index improver and tackifier in certain lubricating greases and specialty oils.
• For use in wire and cable insulation compounds to enhance flame retardancy and environmental stress crack resistance.

Quality Control

Our Chlorinated Polypropylene is manufactured under a stringent quality management system. Each batch is tested against key parameters including chlorine content, viscosity, thermal stability, and color to ensure consistent performance and batch-to-batch uniformity. Comprehensive Certificates of Analysis (COA) documenting these results are provided to guarantee product integrity and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong alkalis and fluorides. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and maintain product quality.
