Product Description
Purified Terephthalic Acid (PTA) 99.5%
Purified Terephthalic Acid (PTA), with chemical formula C₈H₆O₄, is the essential diaromatic acid monomer for polyester production. This white crystalline solid or powder features stable chemical properties and high purity (≥99.5%), ensuring superior performance in downstream polyester applications. As a key intermediate in modern petrochemical industries, PTA is primarily used to produce Polyethylene Terephthalate (PET) for manufacturing polyester fiber, PET bottle resin, polyester film, and engineering plastics.
Core Applications & Industrial Significance
PTA serves as the foundational material across multiple industrial sectors including textiles, packaging, beverages, electronics, and appliances, earning its reputation as the "Mother of the Polyester Industry".
- Polyester Fiber Production (65-70% of PTA usage) - Reacts with Ethylene Glycol to form PET melt for spinning into polyester filament and staple fiber. Offers high strength, elasticity, abrasion resistance, wrinkle resistance, and quick-drying properties for apparel, home textiles, and industrial applications.
- PET Bottle Resin & Packaging (25-30% of PTA usage) - Creates bottle-grade PET resin for liquid food packaging including carbonated drinks, bottled water, and edible oils. Provides excellent clarity, mechanical strength, gas barrier properties, light weight, and recyclability.
- Polyester Film (BOPET) - Produces biaxially oriented polyester film with high strength, transparency, electrical insulation, and dimensional stability for packaging, magnetic recording, electronics, and solar panel applications.
- Engineering Plastics - Used in production of Polybutylene Terephthalate (PBT) for automotive and electronic components.
Production Technology & Quality Standards
PTA manufacturing involves large-scale continuous production through high-temperature liquid-phase oxidation of para-xylene (PX), followed by hydrogenation purification to achieve fiber-grade or bottle-grade purity requirements.
