Questions about Thermoset Composites?
Alluralite - Lightweight Aesthetic Composites

These materials are intended for use in automotive or transportation body panels that require painting. These composite materials exhibit a minimal expansion characteristic. They are not intended to have superior color properties but will provide a suitable surface for adhesion and surface quality.

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 Composites International’s (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.
