Description

Hexanedioic Acid, Polymer With 1,4-Butanediol And 1,2-Propanediol, Dodecanoate is a specialized aliphatic polyester-based polymer, also known as a poly(ester-ether) or a modified polybutylene adipate. This engineered material is valued for its balance of flexibility, biodegradability, and compatibility, making it a versatile component in advanced formulations. It is primarily sought by manufacturers in the polymer, coatings, and specialty chemical industries seeking to modify material properties or develop environmentally conscious products.

Application

• Polymer Modification & Plasticizers: Acts as a polymeric plasticizer or compatibilizer to improve the flexibility, toughness, and processability of rigid polymers like PVC or PLA.
• Biodegradable Materials: Serves as a key component in the production of compostable films, bags, and molded articles due to its aliphatic polyester structure.
• Adhesives & Sealants: Used as a tackifier or base resin in formulating hot-melt and pressure-sensitive adhesives requiring good adhesion and low-temperature performance.
• Coating Resins: Incorporated into polyurethane or polyester coating systems to enhance flexibility, weathering resistance, and adhesion to various substrates.
• Elastomers & TPUs: Functions as a soft segment or chain extender in the synthesis of thermoplastic polyurethane elastomers (TPUs) for footwear, automotive parts, and industrial goods.
• Lubricant & Grease Additives: Employed as a thickening agent or performance additive in synthetic lubricants and greases to improve viscosity index and stability.
