Description

1,12-Diisocyanatododecane is a long-chain aliphatic diisocyanate monomer, a critical building block for high-performance polyurethane materials. Its extended hydrocarbon backbone provides exceptional flexibility, hydrolytic stability, and resistance to yellowing in the final polymer. This product is essential for manufacturers requiring durable, light-stable elastomers and coatings. It is primarily utilized in the synthesis of specialty polyurethanes for demanding applications in automotive, aerospace, and advanced material sectors.

Application

• Synthesis of Light-Stable Polyurethane Elastomers: Used to produce flexible segments in polyurethane (PU) and polyurea elastomers that resist degradation from UV exposure, preventing yellowing and maintaining mechanical properties.
• High-Performance Coatings and Adhesives: Serves as a key component in formulating advanced coatings, sealants, and adhesives that demand excellent flexibility, chemical resistance, and durability in harsh environments.
• Medical-Grade Polymers: Employed in the development of biocompatible polyurethanes for medical devices and implants, where purity and consistent performance are paramount.
• Automotive and Aerospace Interiors: Used in the production of premium, non-yellowing interior components, instrument panels, and seating materials that require long-term color and integrity.
• Specialty Crosslinking Agent: Acts as a crosslinker for polymers requiring enhanced toughness, abrasion resistance, and low-temperature flexibility.
• Research and Development: A valuable reagent for academic and industrial R&D focused on novel polymer architectures, drug delivery systems, and material science.

Quality Control

Our 1,12-Diisocyanatododecane is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and titration to verify critical parameters such as assay, isocyanate content, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this material must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, open flames, and sources of ignition. Containers must be kept tightly sealed to prevent moisture ingress and polymerization.
