Expancel® HP92 microspheres innovation reduces weight,
withstands high pressure

Lightweight materials are in high demand from automotive manufacturers to meet increasingly strict emission regulations and strong consumer interest in fuel-efficient vehicles that do not compromise on performance or passenger comfort.

Our new Expancel® HP92 microspheres solution is breaking boundaries for thermoplastic microsphere fillers in high-pressure manufacturing of underbody coatings and sealants for the automotive industry, with up to four times better volume recovery to original shape after pressurization compared to an older grade of thermoplastic microsphere.


Our technology is aimed at combining and optimizing the pressure resistance associated with glass microsphere grades with the lightweight of thermoplastic microspheres fillers in one refined solution. As a result, Expancel® HP92 thermoplastic microspheres not only improve fuel efficiency but enhance acoustics, seal for harsh weather conditions, and support the reduction of carbon-dioxide emissions.
