                                       The Lightweight Additive for Peak Performance

Improving your Products Performance with Potters Hollow Spheres

Potters Hollow Spheres have developed a world-wide reputation for
improving product performance. Developed originally to extend plastic
compounds, Hollow Spheres are now widely used in diverse
applications such as industrial explosives and as performance
additives for the refractory and ceramic industries.

Scientists, Designers and Engineers rely on Hollow Spheres for
solving application problems and for providing functional values.

Potters Europe offers Hollow Spheres in various compositions such
as Q-Cel® Ultra-Light Weight Reducing Hollow Microspheres
and Sphericel® Ultra-Fine Weight Reducing Hollow Glass
Microspheres.

These microspheres are available in many particle sizes, densities and strengths to meet your
specific requirements. Potters Hollow Spheres are also available with functional surface coatings,
including silane, silver and other metals, and are fully compatible with polyesters, epoxies,
phenolic resins, urethanes, plastisols, thermoplastics and latex; concrete and other building
materials; and emulsion and water gel explosives.

                              Simple but Versatile
                              Potters Hollow Spheres are simple but versatile. Essentially, they are cells
                              made to controlled dimensions. Each cell contains air. To the naked eye, the
                              spheres look like fine powder. When viewed through a microscope, they
                              resemble tiny ping-pong balls. Spheres have thin walls, relative to their
                              diameters and provide a hollow space. The result is a light-weight material
                              with the potential to enhance the properties of a wide range of products.


Why use Potters Hollow Spheres?
They are Lightweight
Hollow Spheres are only a fraction of the density of
commonly used resins. It only takes a small addition
by weight of Hollow Spheres to displace heavier
materials. They simultaneously add volume and
reduce density. If you are looking for buoyancy, no
filler performs as well as Potters Hollow Spheres.
Additionally, they can save material costs; on a
volume basis, microspheres are a fraction of the
cost of resins.

They go with the flow
Potters Hollow Spheres act like tiny ball bearings. They impart flow properties superior to
irregularly shaped fillers. In liquids, conventional fillers tend to increase viscosity because of their
shape and high surface area. Conversely, spheres have the least surface area of any particle
shape. High loading of Hollow Spheres can be achieved without unacceptable increases in
viscosity. At low filler loadings, Hollow Spheres improve pumping and flow rates. The ball-bearing
effect and low overall viscosity also allows faster mould filling.

They are great stress resisters
Potters Hollow Spheres are extremely                                              good at resisting thermal stress in materials subject to
abrupt temperature changes, such as                                               cultured marble bath ware. Hollow Spheres can also
increase the stiffness of composites                                              used in sandwich construction for marine and auto
applications, and help formulate putties                                          and spackling compounds that virtually do not shrink as

They are reliable sensitizers
                                           Potters Hollow Spheres are unsurpassed as
                                           sensitizers for emulsion and water gel
                                           explosives used in mining, quarrying and
                                           construction. The tiny spheres function as
                                           pockets of encapsulated air within the explosive
                                           matrix. When the explosive is detonated, the
                                           pockets of air become hot spots that concentrate
                                           the explosive and generate high temperatures.
                                           PQ Hollow Spheres are more economical as a
                                           sensitizer than flake aluminium, inorganic nitro
and nitrate compounds, and they withstand mixing and pumping pressure better than other
materials.
