Material Notes:
Capron 8351 is a type 6 polyamide graft copolymer developed for injection molding applications requiring a high level of toughness combined with moderate flexibility and faster cycles. It is also available in heat stabilized (Capron 8351 HS) and/or pigmented versions.Capron 8351 is generally recommended for applications such as storage bins, spray gun and power tool handles, trim clips and fasteners, wall anchors, and automotive roof racks.Data provided by Allied Signal.Processing: Max. water content 0.2%. Product is supplied in sealed containers and drying is not required. If drying becomes necessary, a dehumidifying or desiccant dryer operating at 85°C (185 °F). Is recommended. Drying time is dependent on moisture level.Melt Temperature: 240-270 degC (464-518 degF). Mold Temperature: 80-95 degC (176-203 degF). Injection and Packing Pressure: 35-125 bar (500-1500psi) A mold temperature of 80-95 degC (176-203 degF) is recommended, but temperatures of 10-95 degC (50-203 degF) can be used where applicable. 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. Fast fill rates are recommended to insure uniform melt delivery to the cavity and prevent premature freezing. Capron® is no longer a part of the BASF standard line. The BASF nylon products have been consolidated in the Ultramid ® line.
