Carbon Calsil®

Carbon Calsil®, exclusively available from IMS, is an advanced carbon fibre reinforced calcium silicate. It has been designed specifically to be nonwetting and mechanically strong. Carbon Calsil® offers very low shrinkage as well as being highly resistant to thermal shock. Carbon Calsil® is the material of choice for use in aluminium casting such as transition rings, down spouts, sprue bushes and distribution plates.
