Antimony free super bright L-type

short description:

It is made of green and efficient hybrid titanium DH hyti Catalysis (Lcej). lcej does not contain heavy metals.
Its quality index is comparable to the general bright PET flakes containing antimony, except that antimony is not detected and the terminal carboxyl group content is low. It can increase viscosity.
Low-end carboxyl PET flakes/fibers/films and other materials are highly resistant to hydrolysis and alkali.
No heavy metal antimony detected in the product/products, no antimony migration, safe and healthy.
It can solve the problem of excessive antimony content in textile printing and dyeing wastewater of general antimony-containing pet products and meet the requirements of clean production.

The central value of carboxyl end group content shall be determined within the range of ≤ 28mol / T through negotiation between the supplier and the buyer. Once determined, it shall not be changed arbitrarily.

The central value of the chromaticity b value shall be determined by both parties through consultation within the range of ≤ 10. Once determined, it shall not be changed at will.

The central value of diethylene glycol content shall be determined by mutual agreement within the range of ≤1.5%. Once determined, it shall not be changed at will.

Antimony content index. The detection limit of this method is 10ppm, no detection of Nd.
