THERVEK HRA clay-bonded plastic refractory for gunning applications, offering excellent resistance to thermal spalling.
- It is supplied in a plastic, granulated form specifically for gunning applications.
- When used with our proprietary HYRATE unit, it enables plastic refractory gunning using the HYRATE installation method.
Main applications
- High-temperature furnaces
- Incinerators
- Various industrial kilns and furnaces
-
THERVEK PATA patching repair material with excellent adhesion.
- Supplied in a workable, clay‑like consistency, softer than standard ramming plastics, and applied by hand patching (pressing into place).
- Enables easy patch repairs of localized damaged areas in furnace linings.
- After installation, initial adhesion is mechanical, but heating above 350°C sinters the material and significantly increases its strength.
Main applications
- Repair of various industrial kilns and furnaces
-
THERVEK RMA clay‑bonded ramming plastic refractory with excellent resistance to thermal spalling.
- Supplied in a clay‑like consistency, cut into 50mm‑thick slices.
- Slices are placed into the formwork and densely rammed using an air rammer.
- After installation, the lining is initially held in place by the clay’s plasticity, and final strength is developed through firing.
Main applications
- High-temperature furnaces
- Various industrial kilns and furnaces
- Incinerators
