Description

1,4-Benzenedicarboxylic Acid, Dimethyl Ester, Polymer With 1,4-Butanediol And 2,2'-[(1-Methylethylidene) Bis[(2,6-Dibromo-4,1-Phenylene)Oxy]]Bis[Ethanol] is a specialized brominated flame-retardant copolyester engineered for high-performance applications. This polymer is valued for its ability to impart excellent flame resistance while maintaining key mechanical and processing properties. It is primarily sought by manufacturers in the electronics, construction, and transportation industries requiring materials that meet stringent fire safety standards.

Application

• Flame-Retardant Polymer Additive: Key component in engineering plastics and thermoplastic polyesters to achieve UL94 V-0 and other high flame-retardancy ratings.
• Wire & Cable Insulation: Used in sheathing and insulation compounds for electrical cables to prevent flame propagation and enhance safety.
• Electronic Housings & Connectors: Incorporated into resins for connectors, housings, and internal components of computers, appliances, and consumer electronics.
• Automotive Interior Components: Formulated into polymers for under-the-hood parts, connectors, and interior trim to meet automotive fire safety regulations.
• Construction Materials: Used in polymer blends for pipes, conduits, and panels that require inherent flame resistance.
• Thermoplastic Polyester Elastomers (TPEE): Serves as a reactive modifier to introduce flame retardancy into flexible yet durable elastomer formulations.

Quality Control

Our flame-retardant polymer is produced under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality parameters including bromine content, intrinsic viscosity, thermal stability, and flame retardant efficacy are rigorously tested. Certificates of Analysis (COA) detailing key specifications are provided with each shipment. Our production adheres to relevant global standards, and we support compliance with REACH, RoHS, and UL certification requirements for our customers.

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 strong heat sources and open flame. The material should be kept dry to prevent any potential hydrolysis or property degradation prior to processing.
