DE-COMP COMPOSITES, INC.
MB-DC SERIES
Modeling Board
DC-SERIES Modeling Boards are fabricated with thermoplastic polyester polybutylene terephthalate (PBT) which enables post processing treatments such as thermoforming, compression molding, and filament winding. This board is a dense, highly machinable, dimensionally stable, model board for today’s CNC machining applications. As advancement over similar products on the market, DC-SERIES boards yield low dust emission during machining, less abrasiveness to CNC cutters and affords the user a highly defined surface finish.
