aM1 is the central value of intrinsic viscosity, which is determined by negotiation between the supplier and the buyer, and shall not be changed arbitrarily after determination.
bM2 is the central value of the melting point, which is determined by both the supplier and the buyer within the range of 252°C to 262°C, and shall not be changed arbitrarily after determination. cM3 is the central value of the terminal carboxyl group content, which is determined by the supply and demand sides within the range of 18mol/t~40mol/t, and shall not be arbitrarily changed after determination. dM4 is the central value of the chromaticity b value, which is determined by the supply and demand sides within the range of <8.0, and shall not be arbitrarily changed after determination. eM5 is the central value of diethylene glycol content, which is determined by both the supply and demand sides within the range of 0.80% to 2.00%, and shall not be arbitrarily changed after determination. fM6 is the central value of titanium dioxide content, which shall not be changed arbitrarily after it is determined. The content of titanium dioxide may not be measured for glossy polyester chips. |
