Description

Chloriertes Polybutadien, Gehalt An Tetrachlorkohlenstoff <=50 Ppm Und Gehalt An Toluol <=2,5 % Und Mittlere Molare Masse 20.000-200.000 is a high-purity, modified polymer where polybutadiene has been chlorinated to introduce reactive sites and enhance properties such as adhesion, flame retardancy, and chemical resistance. This specific grade is engineered with exceptionally low residual solvent content, making it suitable for demanding applications where purity and consistency are critical. It is primarily used by formulators in the adhesives, sealants, coatings, and rubber modification industries seeking a reliable, high-performance additive.

Application

• Adhesive & Sealant Formulations: Acts as a reactive tackifier and modifier to improve adhesion to difficult substrates like metals and plastics.
• Flame-Retardant Coatings and Compounds: Serves as a chlorinated source to enhance fire resistance in paints, mastics, and polymeric materials.
• Rubber Modification and Compatibilization: Used to improve the oil resistance, weathering, and processing characteristics of various elastomers.
• Corrosion-Resistant Primers and Linings: Incorporated into coating systems for steel and concrete to boost chemical and moisture barrier properties.
• Pressure-Sensitive Adhesives (PSAs): Enhances peel strength and tack in tape and label adhesives.
• Printing Inks and Overprint Varnishes: Improves gloss, flexibility, and substrate adhesion in specialty ink formulations.
• Polymer Blending: Functions as a compatibilizer and property enhancer in blends of polar and non-polar polymers.

Quality Control

Our Chlorinated Polybutadiene is manufactured under a strict quality management system. Each batch is tested to ensure it meets the stringent specifications for residual tetrachloromethane (≤50 ppm) and toluene (≤2.5%), along with molecular weight distribution. Certificates of Analysis (COA) detailing these and other critical parameters are provided with every shipment to guarantee traceability and batch-to-batch consistency for our industrial partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is stable for extended periods.
