Q. What is the recommended drying temperatures for Ultramid® products?
A. Typical drying temps are between 176°F (80°C) degrees to 230°F (110°C) degrees for four hours. Testing with a moisture analyzer will provide a more accurate temperature and time. Review the specific grade data sheet for additional details.
Q. What is the recommended maximum process temperature when molding Ultraform®?
A. Ultraform resins should not be processed above a melt temperature of 460°F (238°C) degrees. Review the specific grade data sheet for additional details.
Q. What is the recommended mold temperature range when molding Ultrason® E and Ultrason P?
A. The typical range is between 248°F (140°C) to 356°F (180°C) degrees. Review the specific grade data sheet for additional details.
Q. What is the maximum melt temperature where one could see a reduction in properties when molding Ultradur® PBT resins?
A. Molding Ultradur PBT above 535°F (280°C) degrees and especially when residence times are long as well as not using at least 30% of the barrel capacity.
Q. If Ultramid has a moisture content of 1%, how long will it take to dry it down to a .1% moisture level?
A. It could take approximately twenty hours of drying time at 180°F (82°C) degrees.
Q. Can using color concentrates with Ultramid resins cause splay?
A. Color concentrates can contain high levels of moisture and, therefore, must be dried. Review the specific grade data sheet for additional details.
Q. What is the optimum injection molding screw recovery time for molding BASF resins?
A. Screw recovery should be set and timed to about two seconds before the mold opens.
Q. Why do you get different shrinkage/dimensions when molding different Ultramid colors?
A. Different pigments and levels can affect shrinkage with some even acting as nucleation agents as well. Specific color shrinkage discussions should be held with BASF.
Q. What can I do in the injection molding process to achieve better surface appearance when molding glass reinforced materials?
A. (ELIMINATE Drying to a lower moisture level), Increasing the injection speed/fill time along with increasing mold temperatures will produce a resin rich surface, which improves the glassy appearance.
Q. Where can I go to find information on BASF Plastic Materials?
A. Information on datasheets, chemical resistant brochures, agency approvals, OEM approvals, training courses, and design information is found on the BASF PlasticsPortal® website: www.plasticsportal.com/usa.
