...) if there is moisture in the material. Even at neutral pHs, the elevated temperatures used for polymer molding or extrusion (175 to 250 °C, or 350 to 500 °F, or more) will cause hydrolytic degradation if there is moisture in the resin. Because of this, polymer resin manufacturers advise drying of the material just...
