UNEXPANDED MICROSPHERES

• Unexpanded microspheres use the heat of the process 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.
• For example U010-185D, the unexpanded microspheres start with a density of around 1.0 g/cc and when expanded can reach densities as low as 0.010 g/cc. The particle size changes from 25 microns to 140 microns.

Important process parameters to help you choose which Dualite Microspheres are right for your application

1.    Process temperatures?

2.   How aggressive is your mixing, blending, pumping and conveying process?

3.   Application type?

DUALITE^® U products are heat expandable polymeric microspheres that posses a wide range of performance characteristics with applicability to a broad spectrum of end uses.

DUALITE^® U products will expand to form a low-density sphere, creating unique, and often, improved end- product properties.

Features

• Expandability over a wide range of temperatures
• A wide scope of performance characteristics
• Most grades available as a dry powder or wet cake

*Additional lead times required when ordering (3 months – negotiable)

Product Stability: The performance of DUALITE^® is dependent on the cumulative effects of temperature, pressure and chemical environment. Since Chase Corporation is not able to exhaustively test all combinations of these variables, this data is furnished as a guideline for selection of an appropriate grade of DUALITE^®.
