Welcome to Spex•Lite® Ultra Light Filler Beads

Spex•Lite® Lightweight Aggregate and Solid Air Volume Filler

Weight Saving Volume fillers and low-cost additives

Spex•Lite® Light Weight Fillers


Spex•Lite®  saw a market need for an ultra lightweight filler material with certain performance characteristics that was not available on the market. Leveraging his decades of experience selling competitive products and his chemical engineering background, Ned invented and was awarded several patents for Spex•Lite® Ultra Light Polymer Foam Beads, which resemble miniature “Nerf” balls. We are continually amazed at myriad uses of Spex•Lite® Ultra Light Filler Beads by our customers.

Spex•Lite® Polymer Foam Beads are created from various polymers and are formed as unique, closed cell, foamed beads having extremely low volume densities. In addition, Spex•Lite® Beads offer unbeatable weight reduction, which enables lower product weights than you would get with ordinary lightweight aggregates. 

Spex•Lite® Beads provide increased filler volumes, substantial insulation properties, improved buoyancy, and likely cost reductions.

Spex•Lite® Ultra Light Filler Beads are an extremely efficient and cost effective filler.  For example, adding roughly 1% of Spex•Lite® Beads by weight of the roofing compound system:

  • Increases profit margins (decrease product cost up to 25%)
  • Decreases the overall weight of the system (reduce weight up to 28%)
  • Improves ergonomics and worker safety (your 55# bucket can now weigh ~40#)
  • Reduces freight costs (ship more units per truckload due to decreased package weight)

With all the ways Spex•Lite® Ultra Light Filler Beads can be used, it has tremendous potential to save you and your company money based on product volume costs, in addition to transportation and freight factors. Call us today to save!

Spex•Lite® Foam Beads Float in Water – Our lightweight filler beads are up to 80x lighter than water. Our beads absorb a negligible amount of liquid or resin, which saves you weight as a lightweight aggregate, or cost as a low-cost additive in a resinous system. This makes Spex•Lite® Beads great for use around, in, and under water applications.

 Spex•Lite® Beads are Incredibly Lightweight – One gallon of water weighs 8.34 pounds.  One gallon of  Spex•Lite® Beads can weigh as low as only 0.09 pounds.  This means that Spex•Lite® Beads can be as much as 88 times lighter than water!
