102.jpg (3709 bytes) NON-RCF Insulation Type "UNIFORM B"

GENERAL INFORMATION
ZIRCAR NON-RCF Insulation Type "UNIFORM B" is a family of high temperature ceramic insulations. They contain specially prepared bio-soluble refractory fibers with inorganic silica binder which is uniformly distributed to create an evenly bonded material.

This product family is designed to deliver low thermal conductivity, excellent thermal shock resistance and stability in applications to temperatures exceeding 1000°C (1832°F).

UNIFORM B materials contain no organic binders and produce no smoke or odor when heated. They exhibit excellent resistance to chemical attack at elevated temperatures making them useful in many varied high temperature applications.

The fibers used in UNIFORM B exhibit a chemistry described in EU regulation (EU Directive 97/69/EC) as "of a manmade vitreous fiber with alkaline oxide and alkaline earth oxide content greater than 18% by weight". These fibers were tested pursuant to EU regulations ECB/TM/27, Rev. 7 Nota Q, Directive 97/69/EC with results that are below regulatory thresholds.

Standard boards are available for immediate shipment from stock. Standard tolerances for boards are +/- 1/4in. on length and width and +/- 1/8in. on thickness.

Custom boards, cylinders, shapes and preparations are available on request. Our forming processes, large inventory of custom tooling and state of the art machining techniques allow a wide variety of sizes and shapes to be made.

Boards can be up to 96in. long.

Special geometries such as disks, rings, custom bore (round corner square, hexagonal, oval, etc.) cylinders, staved cylinders, troughs, channel, angle, custom-machined shapes and others can be fabricated. Machining to tight tolerance, compositional variations and the application of surface rigidizers and hardening agents are available.

Please contact us with your special requirements. We are pleased to contact you if you would like more information or want to discuss custom product availability and pricing.
