Improved creep resistance over A130. May reduce warpage in some parts compared to A130. 50% glass reinforced. 50% glass fiber, improved creep resistance over A130 A three-zone screw evenly divided into feed, compression, and metering zones is preferred. A higher percentage of feed flights may be needed for smaller machines: 1/2 feed, 1/4 compression, 1/4 metering.Information provided by Celanese |
