Excess residence will be visible as black carbon Feed 420-445 (216-229) specs in the melt. Transition 435-465 (224-241) Regrind Level: Typically, up to 25% is recommended but higher levels are Metering 445-475 (229-246) _POSSible with litle or no effect on flow and finish, : Drying Temperature: Although Nylene resins are packaged and delivered Die 445-475 (229-246) in a low moisture state, it is good material handling practice to use a Melt Temp. 455-489 (235-254) hopper dryer to maintain dryness. Should pre-drying be necessary, use settings of 180 °F (82.2°C) air at dew point of -40 at a rate of 1 cu. ft. / hour per pound of resin and a residence time of 2-4 hours. Line Rate pph-rpm Cooling ana Sizing: While both air and water can be used as the cooling 2°" extruder 15-19 medium, air is preferred. The use of air allows additional time for sizing and 3¥2" extruder 35-45 educes residual stress. This aids in reducing warpage, especially in profiles with varying wall sections. If water is used, heat the first section to
4" extruder 65-75 above 100 °F (38°C) to reduce quenching and residual stress. Die Design: Draw down of 30% is typical for all dimensions except wall thickness. Land length: should be around 10x wall thickness.
