Processing Guidelines
Material Handling
Max. Water content:0.01%
To insure optimum part performance, this product must be dried prior to molding and maintained at
a moisture level of less than 0.01%. A dehumidifying hopper dryer mounted on to the molding
machine and equipped with alternating desiccant beds and air temperature/dew point indicators is
and 2 to 4 hours drying time are recommended. Further information concerning safe handling
procedures can be obtained from the Material Safety Data Sheet. Alternatively, please contact your
BASF representative.
Typical Profile
Melt Temperature280-300 °C (536-572 °F)
Mold Temperature100-110 °C (212-230 °F)
Injection and Packing Pressure35-125 bar (500-1500 psi)
Mold Temperatures
This product can be processed over mold temperatures of 80-120 °C; however, for optimizing
surface appearance, dimensional stability and part performance, mold surface temperatures of 100-
110 °C (212-230 °F) are preferred.
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.
Back pressure can be utilized to provide uniform melt consistency and reduce trapped air and gas.
Minimal back pressure should be utilized to prevent glass breakage. recommended to minimize
glass fiber breakage.
Fill Rate
Fast fill rates are recommended to insure uniform melt delivery to the cavity and prevent premature
freezing. Surface appearance is directly affected by injection rate.
