Grade SP2000 CP102 available ex stock in 25 kg bagsSPHERICEL®! hollow glass spheres are used to reduce viscosity in paints and coatings and as lightweight fillers in plastic parts.
They are chemically inert, non-porous, and have very low oil absorption.
SPHERIGLASS®! solid glass spheres The spheres are very strong, with a crush strength in excess of 30,000 psi.
Moh's hardness is 6.0-6.5. Glass spheres have very low oil absorption, about 18 g oil/100 g spheres. Because the spheres are nonporous, they do not absorb resin in a polymer system.
Spheriglass use in Plastics
For use in plastic applications as extenders and performance modifiers in plastics applications, the spherical particles are strong enough to survive injection moulding.
They provide improved flow and handling properties in a variety of applications. Unlike irregularly shaped fillers, spherical particles do not adversely affect the viscosity of resin systems. The glass beads exhibit low oil absorption and also resist stains and thermal degradation.
Spheriglass use in Paints and Coatings
Fine grade products are available in particle sizes small enough for use in a wide range of paints and coatings applications, including topcoats.
