Description

Poly(Imino-1,3-Phenyleneiminocarbonyl-1,3-Phenylenecarbonyl) is a high-performance aromatic polyamide, commonly known as a meta-aramid polymer. This engineered material is valued for its exceptional thermal stability, chemical resistance, and inherent flame-retardant properties. It is essential for industries requiring durable, high-temperature resistant fibers, films, and composite materials.

Application

• High-Temperature Filtration: Manufacture of filter bags and felts for hot gas filtration in cement, steel, and power plants.
• Protective Apparel: Production of flame-resistant (FR) clothing, aluminized proximity suits, and military gear.
• Electrical Insulation: Used in high-temperature electrical insulation papers, slot liners, and wire and cable wraps.
• Aerospace & Automotive Composites: Reinforcement fiber in lightweight, heat-resistant composite components.
• Industrial Seals & Gaskets: Base material for seals and gaskets that must withstand harsh chemical and thermal environments.
• Hose & Belt Reinforcement: Provides strength and thermal durability to industrial hoses and conveyor belts.
• Advanced Papers: Used in specialty papers for applications like battery separators and high-strength substrates.

Quality Control

Our poly(m-phenylene isophthalamide) products are manufactured under stringent process controls to ensure batch-to-batch consistency. Quality is verified through a suite of tests including intrinsic viscosity, thermal analysis (DSC/TGA), and mechanical property assessment. Certificates of Analysis (COA) detailing key specifications are available upon request to support your quality assurance protocols.

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 acids and organic solvents. The material is generally stable under these conditions; prolonged exposure to high humidity should be avoided to prevent any potential moisture absorption.
