Product Description

With more than 20 years development, we have succeeded in exploring our new material--Mollica, whose chemical property is same to Molochite (UK), produced by calcining kaolin at high temperature (1550C) with low Fe2O3 & TiO2 and no crystalline SiO2. It can be used in refractrory and investment casting industries including shell moulds, kiln furniture and tooll bricks etc.
