Microspheres for Lightweight Additives & Polymer Fillers

Dualite: Chase Corporation is an industry leader in Expanded Polymer Microspheres and its Dualite® products offer unique solutions to meet the needs of numerous industries and a broad spectrum of end-use applications.

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.

Microspheres for Lightweight Fillers

Expanded Microspheres

The Dualite Difference

Reduced Weight

Lightweight fillers reduce density of the base material without impacting performance characteristics

Thermal Insulation

Polymeric microspheres have low thermal conductivity, making them ideal for ensuring material integrity in high temperature applications

Reduced Costs

Pound for pound, microspheres are far cheaper than the base material. In using microspheres to fill volume, you save on material overhead with no impact to formulation performance

Sound Dampening

Microspheres help dampen vibrations from the environment. For automotive applications, this includes vibrations from the road and natural, ambient noise during travel

Blowing Approved

Replacing chemical blowing agents with nonreactive microspheres improve safety by reducing overall volatility of the mixture

Diverse SelectionCustomized Solutions

In a variety of sizes and materials, microspheres are designed to your specifications with a solution to every application need

Unexpanded Microspheres

Unexpanded microspheres use heat to expand. When exposed to a sufficient amount of heat, the polymer shell softens while at the same time the encapsulated blowing agent exerts an outward pressure on the shell wall, thus causing expansion.

Expanded Microspheres

Expanded microspheres are used in applications where there is not enough heat in the process to use unexpanded products. Unexpanded microspheres are blended with calcium carbonate and then expanded using a patented process.

Microsphere Versitily

Dualite® Products are created through a patented process that controls expansion and coating application, resulting in lightweight ﬁller with a range of particle sizes, densities, and materials. Dualite Polymer Microsphere products offer unique solutions to meet the needs of numerous industries and a broad spectrum of end-use applications.
