TPA(Terephthalic Acid)

Description

TPA is pure white powder produced from the process of oxidation,.refinement, separation and dryness using Para Xylene, raw material of TPA refined from crude oil. TPA has 3 kinds of products classified as PTA (Purified Terephthalic Acid), QTA (Qualified Terephthalic Acid), and MTA(Medium TPA) by the process difference. TPA is mainly used as raw material for Fibers, Films, and PET Bottles.

Caprolactam

Description

Caprolactam is most often synthesized from the benzene component in petroleum processing. It is a precursor in the synthesis of Nylon-6 and as such, among the most highly used chemical intermediates in manufacturing Nylon-6. It is usually produced as clear liquid form and a flake form. Nylon-6 made of Caprolactam has a wide applications in the artificial fiber industry as well as a structural material in the machinery and electronics industry.
