High-purity crystalline solid with extremely low levels of 4-carboxybenzaldehyde (4-CBA) and acetaldehyde impurities.
Consistent batch-to-batch quality optimized for high-speed polyester melt-phase polymerization.
Low metal content (e.g., Fe, Co, Mn) to minimize thermal degradation and color formation during processing.
Controlled particle size distribution enhancing dissolution kinetics and slurry handling in PTA esterification processes.
Complies with global regulatory requirements including FDA 21 CFR §177.1450 for food-contact polyethylene terephthalate (PET).
Primary monomer for polyethylene terephthalate (PET) resin used in beverage bottles and food packaging.
Feedstock for industrial polyester fibers in textile and nonwoven applications.
Raw material for engineering thermoplastics including PETG and PCT copolyesters.
Key component in specialty polyester films for electronics, photovoltaic backsheet, and graphic arts.
Intermediate in the synthesis of liquid crystal polymers (LCPs) and high-performance aromatic polyesters.
