Highway Safety and Construction

Our Potters® brand glass microspheres and ThermoDrop® pavement markings help safely guide the traveling public, and our hollow microspheres improve the value and performance of construction materials


Our Potters® brand ThermoDrop® thermoplastics produce optimum yield for contractors in the field. Our technology reduces striping equipment down time, reducing the price per foot. Our ThermoDrop® thermoplastics can increase average productivity by 25-35%, with a pelletized system that produces less dust than powdered thermoplastic products. Our bright and clean product significantly improves overall productivity, melts quickly and provides uniformity throughout the job.

Reflective Markings for Roadways and Airports

Our Potters® brand glass microspheres and ThermoDrop® thermoplastic pavement marking system are industry-leading and reliable safety solutions. Our Visibead® safety marking spheres and Ultra 1.9® high index safety marking spheres are cutting-edge reflective markings that are both high-performing and reliable. Our Visi-Ultra® safety marking spheres are our ultimate All Weather Reflective beads, providing enhanced safety to all road users.

Microspheres for Construction Materials

Q-Cel® and Sphericel® low-density, hollow microsphere products reduce weight and improve thermal insulation properties in multiple cement-based and polymer-based construction materials, including energy efficient thermal coatings, fiber cement composites, cast polymers, paving blocks and grouting materials. Our products improve flow properties for viscous mixes, allowing better mold flow. Shrinkage is also reduced as our low-density additives occupy more volume by weight than traditional fillers, making these products ideal for vertical use and patching compounds.
