Description

Hexadecanoic Acid, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol And 4,5,6,7,8,8-Hexachloro-3A, 4,7,7A-Tetrahydro-4,7-Methanoisobenzofuran-1,3-Dione is a specialized polymeric ester derived from palmitic acid, pentaerythritol, and a chlorinated anhydride. This engineered polymer is valued for its ability to impart enhanced flame retardancy, thermal stability, and hydrophobic properties to various material formulations. It is a critical additive for manufacturers in the plastics, coatings, and specialty chemical industries seeking to meet stringent performance and safety standards.

Application

• Flame Retardant Additive for thermoplastics, thermosets, and polymer blends.
• Reactive Modifier in epoxy resin and unsaturated polyester systems to improve fire resistance.
• Plasticizer & Stabilizer in PVC and other halogenated polymer formulations.
• Coating Additive for intumescent and protective coatings requiring low smoke and halogenated flame retardancy.
• Adhesive & Sealant Component to enhance thermal and chemical resistance.
• Wire & Cable Insulation compounds to meet flame retardant (FR) and low smoke zero halogen (LSZH) specifications.

Quality Control

Our production of this polymer adheres to strict batch-to-batch consistency protocols. Quality is verified through parameters including acid value, hydroxyl value, chlorine content, and thermal stability testing. Certificates of Analysis (COA) documenting key specifications are provided with every shipment to ensure compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizers and bases. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
