SPHERE ONE EXTENDOSPHERES™ 350 Hollow Spheres
Categories:	Ceramic; Oxide; Silicon Oxide; Other Engineering Material; Additive/Filler for Polymer
Material Notes:	EXTENDOSPHERES™ hollow spheres are efficient, lightweight additives for most resin systems. When Extendospheres™ replace heavier, more expensive components on an equivalent volume basis, they can reduce raw material costs as well as density. Applications: EXTENDOSPHERES™ 350 hollow spheres are a standard grade. They are recommended for use in cement, grout, sealants, roofing compounds, PVC and latex flooring. They can also be used in high mil-build industrial coatings and mastics. Information provided by Sphere One Inc.
