Plasticizer TPA Terephthalic Acid ISO Factory CAS 100-21-0

 

Terephthalic acid is a White Powder.It is the most dicarboxylic acid produced by p-xylene and is the main raw material for the production of polyester. It is solid at normal temperature. Heating does not melt, rising at 300 ° C. If heated in a closed container, it can be melted at 425 °C. Hard to dissolve in water at room temperature. Mainly used in the manufacture of synthetic polyester resins, synthetic fibers and plasticizers.
