About
We take pleasure in introducing ourselves as one of India’s leading CENOSPHERES AND FLY ASH Processor, Distributor, Transporter and Exporter. In just 20 years of existence, ASHTECH has earned an outstanding reputation and have been able to distinguish ourselves as a leading supplier by constantly defining and refining excellence in products, process and customer care. Cenospheres is a glass hard, inert, hollow silicate sphere. Cenospheres is primarily used to reduce the weight of plastics, rubbers, resins, cement, etc., but also imparts further benefits in many situations. Many of the advantages from the use of Cenospheres, including increased filler loading are directly attributed to the spherical nature of the material.Cenospheres
