Notes: Testing conducted on dry-as-molded specimens at 73°F (22.8°C} Recommended Processing Considerations: PAG Injection Molding - Impact Modified Pressure psi Injection 7-15,000 Hold 5-12,000 Back 0.50 Melt Temperature: Melt Temperature: Nylene® PAG melts at 428°F, (220°C) actual melt temperatures of 440-S60°F (227- 293°C) are permissible, depending on residence time and shot size Mold Temperature: 120-200°F (49-93°C), highly filled grades require 180-200°F (82-93°C) to obtain the best overall surface appearance, higher temperatures will increase crystallinity. Residence Time: should not exceed 6 minutes if possible, less with higher melt temperatures Shot Size: should be between 25-75% of barrel capacity.
Fill Rate: fast fill rates are suggested for best surface appearance. Regrind Level: typically no more than 25% is recommended, with higher levels possible for unfilled grades depending on the end use requirements. Make certain regrind is properly dried to virgin moisture levels. Drying Temperature: 150-180°F (66-82°C) for 2-4 hours, Nylene® PAG should be dried to less than 0.20% moisture for ‘optimum performance. Drying longer than 4 hours or at higher temperatures may cause discoloration of the polymer or adversely affect important physical properties. moisture levels.
