What is BMC? (Bulk Moulding Compound)

BMC Composition: BMC (Bulk Moulding Compound) is pre-mixed fiber reinforced composite material that cures under heat and pressure. It primarily consists of a thermosetting resin, glass fiber reinforcement and filler. The polymer component- normally a thermosetting resins, such a unsaturated polyester or vinyl ester – forms a molecular super structure: Cross linked bonds between the chain molecules bring enhanced characteristics to the product, and are the reason for the superior performances of BMC, compared to other polymers.
