Nano microlite stone is a polymer composites material adding natural stone powder, natural pigments,vacuum casting or molded mineral-filled. It is a non-radioactive elements, environment-friendly , a new reusable green architectural decoration materials.Nano microlite stone solves the drawbacks of the largest natural stone--radioactive,which will not be harmful to humans.If we add nano-materials to natural stone,when tempreture curing and polishing,the material produced is more dense.Meanwhile,the anti-permaebility,wear resistance and mildew resistance avoids the shortcomings of ordinary male practical value.
