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 both parties through consultation within the range of ≤1.5%. Once determined, shall not be changed at will.
Antimony content index: The detection limit of this method is 10ppm, and Nd is not detected.
