'FILLIT' are hollow ceramic microspheres, containing nitrogen and carbon dioxide negative pressurized gas inside. It has great features as very light weight, low density, high compression strength, high melting point, high electrical resistance, low coefficient of heat conduction and coefficient of thermal contraction, high abrasion resistance and many more. Now these days FILLIT is a World’s No. 1 light weight high performance filler material that may replace other mineral filler for various types of industries. It’s reducing product’s cost and weight and also improves multiple performances of the filled products. As a result, FILLITE plays an important role in multiple applications and creates considerable economic benefit for enterprises.
