摘要

The historical production data of SABIC IP, Cobourg, was used to determine effects on colours of compounded plastics, of using extruders of different configurations, incorporating minute variations in pigment compositions and using different grades of resins. The colours had been measured in terms of CIE L~*,a~*,b~* values using a spectrophotometer. The measured L~*,a~*,b~* values were then analyzed and compared to the target values using statistical methods. The differences in the observed trends are discussed.
