Thermal Ceramics TR-20 Block Insulation

TR-20 Block is a superior, high-temperature insulation for service to 2000°F (1095°C). According to ASTM testing procedures, TR-20 exhibits extremely high resistance to breakage to 2000°F (1095°C). Long, maintenance-free service and maximum operating efficiency is assured by TR-20’s unique combination of low conductivity and high stability. TR-20 is also very low in sulfur and iron, making it highly resistant to attack from atmospheric conditions and greatly reducing the possibility of product contamination.

These products can be manufactured in special shapes to fit.

Features:

Low thermal conductivity

Block construction 36" x 12"

Good high temperature strength

Variety of thicknesses up to 7”

Resistant to cryolite vapors

Applications:

Side and end wall insulating material in carbon baking pits

Backup insulation in aluminum pot cells, reheat and pusher furnaces, copper reverberatory furnaces, and oil-fired water tube boilers

Curved Block

Interior and exterior use on bustle pipes, hot air pipes, stacks and other curved or circular equipment

customer specifications, saving money on both installation and energy costs.
