1/32 Milled Fibers Milled Fibers are glass filaments coated with a specific sizing to enhance resin compatibility and milled to a specified bulk density. Unlike chopped strands, which are chopped to a precise strand length, milled fibers are milled to an average bulk density, which is determined by the input glass and process conditions. 1/32 Milled Fibers is a fine powdered glass fiber used as a reinforcement to increase mechanical strengths of resins. |
