We have been involved in developing the market for expandable thermoplastic microspheres since 1988. These unique polymer microspheres have various applications in different industries.

Our product range includes both unexpanded and expanded microspheres.

Expandable thermoplastic microspheres are microscopic spheres comprising a thermoplastic shell encapsulating a low boiling point liquid hydrocarbon. When heated to a temperature high enough to soften the thermoplastic shell, the increasing pressure of the hydrocarbon will cause the microspheres to expand. When the heat is removed microspheres remain in their new expanded form with gas entrapped in a closed and elastic cell structure. The volume can increase by 40 to 80 times depending upon the grades.

Thermoplastic microspheres can be used in numerous applications to achieve different properties.

Thermoplastic microspheres can be used in many different processes.

Some examples are Coating, Spraying, Impregnation, Moulding, Extrusion, Injection Moulding, and many more.

Characteristics that make expandable microspheres unique are:

• Ability to expand

• Saving in cost

• Ultra-low density when expanded

• Resiliency

• Closed cells that can be distributed evenly

• Can introduce pressure in the production process

• Improved adhesion

• Surface modification
