High strength,being hollow, low density spheres provide many advantages including: improved fluidity,durability, thermal insulation, sound insulation and density reduction.
Applications are adhesives, sealants, grouts, cements, mortars, roofing materials, mastics, wall boards, ceiling boards, flooring materials, laminates, moldings, castings, insulating materials, and many types of industrial coatings.
