Potters Europe
Engineered Glass Materials Division
Potters Europe is the European division of Potters Industries LLC., the largest producer of glass microspheres in the
world, with a global network of 25 production plants throughout Europe, North and South America and Australasia.
From production plants strategically located close to our customers throughout Europe, Potters supplies
performance Glass Microspheres for a variety of applications, throughout Western and Eastern Europe, Africa and
the Middle East.
For some years, Potters Europe has been researching and developing Glass Microspheres for use in the functional
fillers industry, and as a result, the company launched its Engineered Glass Materials Division (EGM), complete with
a Technical Centre. This innovation provides expert engineers offering technical support, training, state-of-the-art
equipment for research and development, and a sales force dedicated solely to the industry
Glass Microspheres Technology
Solid and Hollow Glass Microspheres are unique additives for thermoplastic and thermosetting resin systems. Glass
Microspheres are smooth, hard and offer excellent chemical resistance as well as outstanding processing and
physical properties. Potters Europe can offer Solid Microspheres in both Soda-Lime (A) and Borosilicate (E) Glass and
Hollow Microspheres in various proprietary compositions.
Borosilicate is chosen for its very low sodium content and low coefficient of
thermal expansion. Formulators in Automotive, Aerospace, Chemical,
Electronic, Industrial, Engineering and other industries are using Microspheres
to enhance performance and reduce reject rates in production. Solid Glass
Microspheres have an outstanding record of improving thermoplastic and
thermoset properties. Recently, significant density reductions are possible
with the latest Hollow Glass Microsphere technology
increase surface hardness and improve stress distribution.
Dimensional Stability
Better stress distribution is achieved from the use of a
spherically shaped particle. With glass microspheres, the
stress pattern is regular and predictable, showing less
localised stress concentrations.
.
Birefringence patterns show stress patterns in resin surrounding different shapes of filler particles.
Note uniform stress patterns around the microsphere

Spheriwhite® Colour Enhancing Microspheres
Spheriwhite® has been developed for a range of markets
where colour is important. These include “white-goods” in
household appliances, leisure and medical equipment, and
for the paints and coatings industry.. It is a result of several
years of research and testing, using the expertise of the
engineers at the EGM Technical Centre. A specific process
has been researched, developed, and now patented.
Spheriwhite® Solid Glass Microspheres controls the
whiteness of a polymer in its final product where there is no
pigment, and enhances the colour where there is a pigment
present. Spheriwhite® is also cost-effective: it can be used in
conjunction with expensive alternate pigment whiteners that
are currently used to enhance colour or to whiten, therefore
cutting manufacturing costs as well as improving overall
appearance.

Sub-sieves Ultra Fines Microspheres
Sub-sieves joins the growing range of performances functional
fillers, supplied by Potters Europe and is suitable for a range
of markets where colour is important and very fine controlled
top cut is critical. These include Masterbatch for BoPP Films,
Food packaging, Coatings for laminates, Wood varnishes, Top
coat/gel coat, coil coiling, thin film decorative paints, light
diffusion films and Agricultural Film among others.
Based on the same technology platform as our Spheriglass
solid microspheres, these highly calibrated grades ensure a
tight control of particle size and ensure that no particles are
above a given threshold.
Glass composition and impervious surface of the
microspheres improve film integrity and durability
They contribute to an effective barrier against
corrosion, chemicals, reducing surface porosity
They are typically used to improve hardness, add
burnish, scrub and abrasion resistance
They give minimum impact in clear coatings. Gloss
level could be controlled by loading ratio
Due to the chemistry, they are also UV transparent and
have utility in radiation-curable and thin film powder
coatings
They also block shrinkage and Warpage and enhance
impact strength

Q-Cel® Ultra-Light Weight Reducing Microspheres
Q-Cel® Hollow Microspheres offer the opportunity to manufacture low-density products with enhanced properties and performance. These performance microspheres are engineered speciality functional fillers that significantly reduce density and enhance mechanical properties. Q-Cel® products have a density of approximately one-fifth
that of most thermosetting resins. On an equal weight basis, the Q-Cel® Hollow Microspheres occupy about five times more volume than the resin, which can reduce compound weight, reduce VOC content and cost. They also provide other desirable properties, such as increased impact resistance, improved finishing characteristics and
better thermal shock resistance and are formulated with a proprietary fired glass composition.
Typical Properties of Q-Cel® Lightweight products
Typical Properties of Q-Cel® High-Strength Products
Applications include automotive repair compounds, mouldings and thin-films as low as 4 mils. These Microspheres used alone or in combination with other Q-Cel® Hollow Microspheres or conventional fillers, will provide maximum filler loadings and low compound densities at the desired viscosity. Samples in sufficient quantity for testing are available upon request.
Potters Europe offer a range of Q-Cel® Hollow Microspheres for applications with moderate pressure and shear. Formulators may choose Q-Cel® Microspheres according to working pressure and desired density. These single-cell particles are white, free-flowing, have a hydrophobic coating and are used in many markets such as Automotive as car putty, Construction in cultured marble applications, and Mining as a sensitizer for explosives
