Injection molding
Max. Water content: 0.20%
Product is supplied in sealed containers and
drying prior to molding is not required. If drying
becomes necessary, a dehumidifying or desiccant dryer
operating at 80 degC (176 degF) is recommended. Drying time is
dependent on moisture level, but 2-4 hours is generally
sufficient.
Further information concerning safe handling procedures
can be obtained from the Material Safety Data Sheet.
Alternatively, please contact your BASF representative.
PROCESSING
Melt Temperature 280-304 degC (536-580 degF)
Mold Temperature 60-100 degC (140-212 degF)
Injection and Packing Pressure 35-125 bar (500-1500 psi)
Back Pressure 0-0.35 MPa (0-50 psi)
Screw Speed 40-80 rpm
Screw Compression Ratio 3:1 to 4:1

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.

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.
