Description

1,4-Benzenedicarboxylic acid polymer with [1,1'-biphenyl]-4,4'-diol, 4-hydroxy benzoic acid, 6-hydroxy-2-naphthalenecarboxylic acid and N-(4-hydroxyphen yl)acetamide is a high-performance, multi-component thermoplastic copolyester. This engineered polymer is valued for its excellent thermal stability, mechanical strength, and chemical resistance, making it suitable for demanding technical applications. It is primarily sought by manufacturers in the advanced plastics, specialty fiber, and high-temperature film industries.

Application

• High-Performance Engineering Plastics: Used as a matrix resin for injection molding and extrusion of components requiring high heat deflection temperatures and dimensional stability.
• Specialty Fibers and Filaments: Serves as a precursor for high-tenacity, thermally resistant fibers used in industrial textiles and advanced composites.
• Barrier Films and Coatings: Employed in the production of films with excellent gas barrier properties for specialized packaging and electronic applications.
• Automotive Components: Utilized in under-the-hood parts, connectors, and other components where resistance to heat, fuels, and oils is critical.
• Electrical and Electronic Insulation: Applied in the manufacture of insulating films, connectors, and circuit board substrates due to its good dielectric properties.
• Industrial Membranes: Used in filtration and separation membranes that require chemical and thermal robustness.

Quality Control

Our production of this high-performance polymer adheres to stringent quality management systems, including ISO 9001 standards. Each batch is characterized for key parameters such as intrinsic viscosity, thermal transition temperatures (DSC), and melt flow index to ensure batch-to-batch consistency and performance reliability. Comprehensive Certificates of Analysis (COA) detailing these specifications are provided with every shipment.

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 incompatible materials. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption which can affect processing properties.
