PET (Polyethylene Terephthalate) textile grade includes features like high Reaction Speed – low thermal degradation, bright whiteness, resistant against yellowing and deterioration. And also High Degree of Polymerization – high crystalline regions, concentrated molecular weight distribution.
Polyethylene Terephthalate fiber grade chips (normal viscous ) is formed in the plan plant within five consecutive process stages. The stages are esterification 1,2, prepolycondensation 1,2 and polycondensations.
Application:
- Semi dull
- Suitable for fiber for textile
- Artificial thread applications
