SMC(Sheet Molding Compound)

Go to the previous page
SMC (Sheet Molding Compound) SMC is a thermosetting composite molding material in sheet form, created by impregnating glass fiber stiffener into a resin compound of unsaturated polyester resin and additives that include low profile agents, lubricants, and fillers and then increasing the viscosity of the resin compound using chemicals.
  • The Characteristics of SMC

    • 1) SMC has excellent mechanical strength.
    • 2) SMC has good workability ; it is easy to handle and also easy to inject into molds due to its non-stickiness.
    • 3) SMC has excellent productivity; SMC makes it possible to product large quantities of products in a short amount of time compared to the existing FRP molding method.
    • 4) SMC has excellent levels of stain resistance, water resistance, weather resistance, and corrosion resistance.
    • 5) SMC has high heat deflection temperatures and suffers little thermal aging.
    • 6) SMC comes in various colors.
    • 7) SMC is guaranteed to have a semi-permanent lifespan; SMC can be used for long periods of time because it does not rust or corrode easily compared to metal and wood.
    • 8) SMC has excellent dimensional accuracy.
      SMC grades with low - or non-shrink properties can be used for precision parts.
  • Handling Precautions

    Storage
    • 1) Avoid storage places with high temperatures and store SMC at a temperature of 20℃ or below.
    • 2) Avoid direct sunlight and store SMC in a cool dark place.
    • 3) Ensure that SMC’s packaging is not damaged during its storage.
      (Damaged outer packaging volatizes SMC, making it unusable.)
    At Work
    • 1) Ensure that SMC does not come into contact with direct sunlight or moisture at the work site.
    • 2) Be sure to store only the day’s production of SMC at the work site if possible.
    • 3) Be sure to use the material immediately after removing its packaging (AL film).
    • 4) When SMC is to be left unattended for more than 30 minutes after its PE/PP film is removed, be sure to re-wrap it with Al film prior to storage.
    • 5) Be sure to wear a dust mask and protective glasses before commencing work.
