33% glass reinforced, heat stabilized, impact modified PA66 black with a combination of excellent impact resistance, toughness and strength.

Nylon 66 materials must be properly dried in order to provide parts with optimum strength and toughness. Nylon 66 materials are hygroscopic and will become degraded by excessive moisture during the injection molding process. For unopened bag/box, dry at 60 degC (140 degF) for 1-2 hours. For material exposed to the atmosphere, if additional drying is needed, dry at 66 degC (150 degF) or until the moisture level is between 0.04 - 0.20%.

Typical Profile
Melt Temperature: 288-305 degC (550-581 degF)
Mold Temperature: 60-100 degC (140-212 degF)
Injection Pressure: 35-125 MPa (5000-18000 psi)


Back Pressure: 0-0.35 MPa (0-50 psi)
Screw RPM 40-80
Screw Compression Ratio:3:1-4:1


Mold Temperatures
This product can be processed over a wide range of mold temperatures; however, for applications where aesthetics are critical, a mold surface temperature of 60-100 degC (140-212 degF) is recommended.

Pressures
Injection pressure controls the filling of the part and should be applied for 90% of ram travel. Packing pressure affects the final part and can be used effectively in controlling sink marks and shrinkage. It should be applied and maintained until the gate area is completely frozen off.

Fill Rate
Fast fill rates are recommended to ensure uniform melt delivery to the cavity and prevent premature freezing.
