Low Density, Paintable Sheet Molding Compound

This product line consists of several low density sheet molding compounds from 1.2 – 1.5 specific gravity that are suitable for both class A painted surfaces and structural parts. The class A materials will also withstand the high temperatures associated with the painting process. The structural materials are quite suitable for numerous applications that require weight bearing and high rigidity.

Please note: all of our materials are custom developed to meet your specific requirements, if you don't see a product performance metric that meets your needs, call us to discuss your specific project requirements at 317.773.1766 or email us at

The information on this sheet is a guide. The stated values reflect an average of several tests conducted on CI's goods. These values were obtained under ideal conditions and may not be replicated in any particular test, part, or application. Because the values achieved in actual parts depend considerably on part design, molding conditions, and testing methods, no guarantee is made or implied regarding values to be obtained in any specific test, part, or application. CI makes no warranty or representation as to the suitability of any of its goods for use in any application. CI relies on customer to conduct its own tests and judge for itself the suitability of CI's goods.
