Slide Rule


Blair Rubber Company provides a complete lining system; technical service, material, cements, and repair material.

This slide rule contains chemical resistance ratings that have been developed from various sources. The purpose of this data is to help you narrow the choice of materials when selecting the proper liner for your specific needs. For the best recommendations on specifying all your rubber linings, please check with Blair’s technical department.

Allow a safety margin beyond the most extreme conditions you expect. Wear due to abrasion, impact, temperature extremes inside and outside the lined equipment, and strongest concentration of chemical components all affect the life of the lining.

The final selection of linings for a particular service should not be made without advice from Blair’s technical department.
