Cancarb Data Sheet Describes Thermax® as High Temperature Insulation

Cancarb Limited has published a new data sheet called Thermax^® as High Temperature Insulation that explains why grades of its Thermax^® Powder are used in high-temperature furnaces and reactors that produce advanced materials. These medium thermal carbon blacks combine low thermal conductivity with high carbon purity, chemical inertness, low combustibility, and heat resistance up to 3200°C. They also cost significantly less than synthetic graphite and carbon felts.

Recognizing that furnaces and reactors differ, Cancarb provides four grades of Thermax^® Powder to address application-specific needs.

Today, many advanced materials are produced in furnaces and reactors where operating temperatures can exceed 3000°C. With their low thermal conductivity, Thermax^® Powders help minimize heat loss and maximize energy efficiency. ASTM testing demonstrates that the thermal conductivity of these Cancarb products is comparable to that of synthetic graphite and carbon felts.

Non-carbon impurities can cause clinker and hot spots that jeopardize furnace and reactor integrity. Thermax^® Powders are produced from sulfur-free methane gas, and Cancarb’s processing techniques result in low ash content and extremely low sieve residue levels. In conjunction with their chemical inertness, their high carbon purity results in low combustibility.

Among their advantages, Thermax^® Powders from Cancarb can be packed as tightly as possible for uniform thermal conductivity and the absence of voids that can create hot spots. Their low surface area increases the life of the thermal insulation, and their low structure reduces degassing time and ensures a consistent insulating layer.
