Microsphere applications banner Microsphere applications banner Microsphere applications banner Dualite microspheres are industry leaders in lightweight material fillers. These highly customizable beads offer substantial weight reduction to a material, while preserving optimal characteristics of the mix. In many case, Dualite microspheres bring further benefits due to their quality insulation.
Dualite® Microspheres are microscopic ultra-lightweight fillers made from a flexible polymer shell. The microspheres come in 2 forms: Unexpanded microspheres that can expand in process as an alternative to blowing agents, and Pre-expanded microspheres.
Dualite® can be added to plastics, resins, adhesives, and composites. Their inclusion produces a number of benefits depending on the application, including lower density, reduced cost, improved insulation, VOC reduction and improved machining.
Engineered microspheres are instrumental in advancing automotive manufacturing by enabling significant lightweighting across interior, exterior, and under-the-hood components. Incorporated into plastics, composites, adhesives, and coatings, they reduce component density while improving the strength-to-weight ratio. This innovation leads to enhanced fuel efficiency and EV range, along with superior NVH (noise, vibration, and harshness) performance and thermal insulation. Manufacturing processes benefit from improved material flow, reduced sink marks, and easier sanding. By using less material and lowering vehicle weight, microspheres contribute to both cost reduction and sustainability goals. Let us help you drive your next project forward.

Integrating engineered microspheres into composite materials unlocks significant performance advantages. These advanced additives are key to reducing density and dramatically improving the strength- and stiffness-to-weight ratios in fiber-reinforced plastics, resin systems, and laminates. Beyond weight reduction, they offer better dimensional stability and a smoother surface finish. The processing benefits are equally compelling, including improved flow, lower shrink, and easier sanding or machining. This leads to enhanced fatigue resistance, superior thermal and acoustic insulation, and better corrosion resistance in the final product. Let us help you optimize your composite formulations.
