Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 2,2-Dimethyl-1,3-Propanediol, 1,6-Hexanediol And 1,1-Methylenebis4-Isocyanatobenzene CAS NO 27417-33-0 is a high-performance, segmented polyurethane or polyurethane-urea copolymer. This engineered polymer is valued for its exceptional balance of mechanical strength, chemical resistance, and versatile processing characteristics. It is a critical raw material for formulators and manufacturers requiring durable, flexible, and resilient materials. Key industries that utilize this advanced polymer include coatings, adhesives, sealants, elastomers (CASE), and specialty plastics.

Application

• High-Performance Coatings: Used in formulating durable protective coatings for industrial equipment, automotive components, and marine applications requiring excellent abrasion and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a key binder in structural adhesives, potting compounds, and flexible sealants where strong bonding and environmental durability are paramount.
• Engineering Elastomers: A base polymer for manufacturing castable polyurethane elastomers used in rollers, wheels, gaskets, and impact-absorbing parts.
• Thermoplastic Polyurethane (TPU) Production: Can be processed into TPU pellets for injection molding or extrusion to create flexible films, hoses, cables, and wearable device components.
• Fiber & Textile Finishing: Employed in coatings for synthetic leather, waterproof textiles, and high-tenacity fibers to enhance durability and performance.
• Composite Materials: Acts as a matrix or modifier in composite systems to improve toughness, adhesion, and compatibility between different material phases.

Quality Control

Our production of this specialty polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as molecular weight distribution, isocyanate (NCO) content, hydroxyl value, and viscosity are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment. We support compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, open flames, and sources of ignition. Due to potential moisture sensitivity, containers should be kept sealed when not in use to prevent degradation from atmospheric humidity.
