Elmira presents bio-based Pre-preg “Coral”

High water and chemical resistance - flame retardant version to follow

Elmira has introduced a range of bio-based pre-pregs, available with a selection of glass fibre and carbon reinforcements along with naturally derived fibre alternatives. “Coral” HIPP high impact pre-pregs are styrene free and are based on cashew nut shell liquid. The materials are the first commercially available bio-based pre-preg. A “Coral” fire retardant variant will also soon be available for mass transport and aerospace applications.

These materials provide not only comparable curing characteristics, thermal stability and mechanical performance to conventional epoxy based pre-pregs but also offer increased impact strength along with better water and chemical resistance. The materials are suitable for a wide range of processes and curing requirements displaying high flow and laminate quality.
