BASF Capron® BU50I Ultratough Nylon 6 (Dry)

Subcategory: Nylon; Thermoplastic; Nylon 6

Close Analogs: This product is no longer a part of the BASF NAFTA standard product line.

Material Notes:
Capron Ultratough Nylon BU50I is an unfilled nylon 6 product that maintains its impact strength and ductility to -40 deg F (-40 deg C). The extreme low temperature tolerance of Ultratough Nylon BU50I makes it ideal for applications in which the weldline impact strength at low temperatures is critical.

Capron BU50I is generally recommended for automotive components, small engines, power tool parts and casings, cold weather and high impact supports gear, such as snowboards, ski components, helmets and hockey masks.

Processing: Max. water content 0.15%. 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: 270-315 degC (520-600 degF). Mold Temperature: 70 degC (158 degF). Injection and Packing Pressure: 35-125 bar (500-1500psi) A mold temperature of 70 degC (158 degF)is recommended, but temperatures of 10-85 degC (50-185 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. Injection speeds of one inch of ram travel per second are typical.
