Description
Clipper DP Fire Brick is engineered for extreme heat and heavy-duty applications. This high-density fireclay brick delivers exceptional strength under pressure (900-1600 PSI) and withstands temperatures up to 3100°F, making it ideal for industrial kilns, furnaces, and other high-heat environments. For long-lasting performance, it maintains structural integrity even in repeated heating cycles.
As a 42% alumina hard brick, it combines durability with thermal stability. The rugged composition minimizes wear, reduces thermal shock, and ensures long service life in demanding setups. Its dense matrix helps resist slag attack and maintains precise lining dimensions for consistent operation.
