| Extrusion instructions |
|---|
| NA 442 has excellent drawdown characteristics that yield outstanding output rates. Optimum properties are obtained over a broad range of extrusion conditions at melt temperatures between 330°-380°F (166°-194°C) and a blow-up ratio between 1.7-3.0:1. Using proper techniques and equipment, NA 442 can be drawn to 1.0 mil (19 microns) at commercial production rates. |
