What is BMC…?
Bulk Molding Compound (BMC) is an unsaturated polyester (or vinyl) resin-based, short glass fiber (usually 3mm, 6mm, 9mm), or other fiber like natural fiber reinforced composite compound material. (Bulk Molding Compound (BMC)
Other different functional fillers and agents like shrinkage additive, pigment, release agent, catalyst, etc. are added and evenly stirred to formulate it to be a stable, moldable material for producing different complex components.
Fiberglass in BMC is shorter than that in SMC, so BMC material flows even better than SMC and can be made for a better finish or more complex.
BMC Characteristics
Lightweight, electrical insulation, fire-resistant, corrosion-resistant, heat resistant, weatherproof, low shrinkage, stable dimension control, superior flowing ability, those varieties of special properties rolled into one, making bulk molding compound (BMC) a most ideal material for making small but more complex, precise products that are used in various industries. 💶
Bulk Molding Compounds (BMC) and Sheet Molding Compounds (SMC) are both fiber reinforced materials. So how are they different and how do we choose them? This article will give you a detailed introduction.
What is SMC 📕
differences between SMC & BMC
Sheet Molding Compound (SMC) is an unsaturated polyester (or vinyl) resin-based, chopped glass fiber (usually 1 inch) or other fiber like natural fiber reinforced composite compound material. Other different functional fillers and agents like shrinkage additive, pigment, release agent, catalyst, etc. are added to formulate it to be a stable, moldable material for producing various complex components.
SMC has even longer fiberglass which strengthens the material for producing stronger, larger products. In some conditions, continuous glass fiber or even glass fiber mat is used to strengthen SMC material.
SMC Characteristics
The SMC material has light weight, high mechanical strength, electrical insulation, fire resistance, corrosion resistance, heat resistance, weather resistance, low shrinkage, stable dimensional control, and uniform material thickness.
SMC material is the best material for heavy duty truck/body parts (Class A surface) manufacturing
