DFDA-1254 NT provides excellent surface finish and outstanding output rates over a broad range of conditions. For optimum results, use melt extrusion temperatures in the suggested range of 338 to 392°F (170-200°C). However, specific recommendations for processing conditions can be determined only when the application and type of processing equipment are known. Please contact your local Dow Chemical Wire and Cable Sales Representative for such particulars. | |||||||||||||
