SMC(Sheet Molding Compound)
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.

Characteristics
- 1) They have excellent mechanical strength * They are economical because they can be used to reinforce parts that particularly require strength.
- 2) Their excellent fluidity makes them ideal to use for filling curved or ribbed parts, and they are less prone to dents.
- 3) They are non-shrink materials with high levels of dimensional accuracy and good surface smoothness.
- 4) They have excellent paintability. * The painting process is shortened due to their excellence surface smoothness.
- 5) They have excellent heat resistance; they have reduced vulnerability to aging caused by high heat coming from engines, etc.
- 6) They have excellent vibration damping capabilities. * They can be used to reinforce vibration parts and do not crack.
- 7) They are non-shrink materials with excellent flammability.
