Unsaturated Polyester Compound

RIGOLAC BMC

About the product

Resonac supplies RIGOLAC BMC (Bulk Molding Compound), a thermosetting molding material composed primarily of RIGOLAC unsaturated polyester resin, combined with fillers and glass fibers.
It offers good moldability along with well-balanced mechanical properties, heat resistance, and electrical insulation.
With low molding shrinkage and a low coefficient of linear thermal expansion, it provides good dimensional accuracy.
In addition, its high flowability enables low-pressure molding, contributing to flexible processing and stable production.
