SMC is abbreviation of Sheet Molding Compounds, which mainly consists of the special spinning unsaturated resin, Low shrinkage agent, fiberglass, filler and many kinds of accessory ingredients.

Product Features

SMC sheet has good features of electric, anti-fire, excellent mechanical, smooth surface etc.

1)  anti-UV, anti-corrosion, anti-acid and alkali.

2)  long lifespan to be 15 years above outdooor.

3)  good insulation.

4)  very  light to be transportation easily.

5)  without any harmless component, no pollution to surroundings.

6)  excellent anti-fire feature.

7)  without painting on SMC products, easy maintenace.

No.
