EFI Composites Featherlite FL4005C Calcium Carbonate/Thermoplastic Microspheres
Categories: Ceramic; Other Engineering Material; Additive/Filler for Polymer

Material Notes: Featherlite FL4005C is a concentrated blend of thermoplastic microspheres and high purity calcium carbonate combined with an effective dust suppressant. Featherlite is ideal for weight (up to 25%) and cost reduction (up to 30%) in both neat and filled resin systems. These low dust blends are designed to be used in areas where dust sensitivity is a priority while improving product wet out and lowering resin demand. The calcium carbonate offers greater heat resistance than alumina tri-hydrate and calcium sulfate allowing working temperatures of up to 280 degrees F. The high whiteness if the C series is perfect for color sensitive applications.
