Prastic Refractories

PRM Series

Potentram is a plastic refractory made by mixing a stable refractory material with clay or a special chemical binder that has excellent plasticity and adding water to create a paste-like refractory material. It is an all-in-one structure without the need for wooden forms, allowing for complex and diverse construction. The use of simple construction methods such as hammering or air ramming makes it easy to construct in various areas. Additionally, it has excellent thermal, physical, and chemical properties.
