Product type
Purified Terephthalic Acid (PTA) is a key raw material used in the production of polyester fibers and resins. It is a white crystalline powder that is produced through the oxidation of p-xylene in the presence of a catalyst. PTA is essential in the manufacturing of various polyester products, including textiles, plastics, and films, due to its excellent properties such as durability and resistance to heat and chemicals.
| Purity | Typically above 99.5% |
| Form | White crystalline powder |
| Melting point | Approximately 250°C |
| Moisture content | Usually less than 0.1% |
| Packaging | Typically available in bulk or 25 kg bags |
When selecting Purified Terephthalic Acid, buyers should consider the required purity level, as higher purity can enhance the quality of the final product. It is also important to specify the form of PTA needed, whether in bulk or packaged. Additionally, buyers should inquire about moisture content and any specific certifications that might be necessary for their applications.
