Low end carboxyl antimony free super bright LC type

short description:

Characteristics
It is made of green and efficient hybrid titanium DH hyti Catalysis (lcej). Lcej does not contain heavy metals.
Except that antimony is not detected and the end carboxyl group is low, other quality indexes are equivalent to those of general antimony containing bright PET chips. It can increase viscosity.
Low end carboxyl PET chip / fiber / film and other materials have stronger hydrolysis resistance and alkali resistance.
No heavy metal antimony is detected in the product / product, 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 cleaner production.

Application

It can be directly spun / film made, or processed after tackifying; It can be used for back plate membrane, geotextile, super fiber cloth, etc.

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 chromaticity b value shall be determined within the range of ≤ 10 by both parties through negotiation. Once determined, it shall not be changed arbitrarily.

The central value of diethylene glycol content shall be determined within the range of ≤ 1.5% through negotiation between the supplier and the buyer. Once determined, it shall not be changed arbitrarily.

Antimony content index: the detection limit of the method is 10ppm, and Nd is not detected.
