Material Handling
Max. Water content: 0.01%
To ensure 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 Temperature 280-300 °C (536-572 °F)
Mold Temperature 100-110 °C (212-230 °F)
Injection and Packing Pressure 35-125 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 ensure uniform melt delivery to the cavity and prevent premature freezing. Surface appearance is directly affected by injection rate.
