Bulk Molding Compound Material
Bulk Molding Compounds BMC material are used in compression, transfer and BMC injection molding processes.
BMC material is available in bulk bags as well as slug form. The mixing operation can be done in a number of ways.
Normally there are three methods for combining glass with paste to realize the BMC material:
The process chosen for BMC material mixing is dependent upon specific product properties, product form and volume.
BMC material is a thermoset plastic made up of a polymer resin, various inert fillers, fiber reinforcement, catalysts,
stabilizers, and pigments that form a viscous, 'playdough like' compound for molding. BMC material is highly
filled and reinforced with short fibers. Glass reinforcement represents between 5% to 30%, with glass length
typically between 1/8" and 1/2".
Depending on the end-use application, compounds are formulated to achieve tight dimensional control,
flame resistance, high dielectric strength, corrosion and stain resistance and color stability.
Its excellent flow characteristics make BMC material well suited to a wide variety of applications requiring
precision in detail and dimensions. The BMC material is available in a wide variety of colors.
