A Message from IDI Composites International

IDI Composites International World Headquarters

IDI Composites International (IDI) is the premier global custom formulator and manufacturer of thermoset molding compounds for molders and OEMs.

The IDI 3i Composites Technology Center

The 3i Composites Technology Center is the research and development division of IDI Composites International.

IDI Introduces Fortium™ and Ultrium™

IDI Composites International and The IDI 3i Technology Center have expanded their line of Structural Thermoset Composites STC®. Fortium™, high percentage glass fiber composites and Ultrium™ carbon fiber based composites were developed to address the performance gap that exists between dense metals and more costly advanced composites to give molders and OEM’s a new material option to consider when designing products that require high strength, but where weight and cost are a consideration.
