Nylene® 2407 HSSP
Technical Data Sheet
High viscosity nylon copolymer with high impact resistance and superior flexibility
Optimized with good melt strength for high line speeds in thin wall sections, and is available in natural and black
One of a family of grades specifically designed for the convoluted tubing industry, but can also be used for other extrusions and some molded parts.
Testing conducted on dry-as-molded specimens at 73°F (22.8°C}
Recommended Processing Considerations: High Viscosity Extrusion
Residence Time: Screw should not be left idle for more than 3-4 minutes with melt in the barrel. Excess residence will be visible as black carbon specs in the melt.
Regrind Level: Typically, up to 25% is recommended but higher levels are possible with little or no effect on flow and finish.
Drying Temperature: Although Nylene resins are packaged and delivered in a low moisture state, it is good material handling practice to use a 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.
Cooling and Sizing: While both air and water can be used as the cooling medium, air is preferred. The use of air allows additional time for sizing and reduces residual stress. This aids in reducing warpage, especially in profiles with varying wall sections. If water is used, heat the first section to 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.
