High Temperature Insulation

Lynx Brand Tufnol

Lynx Brand Tufnol is a good quality fine weave grade for mechanical and electromechanical applications. Lynx Brand Tufnol has good mechanical strength and wear resistance with good electrical properties for this class of material. Machining characteristics are good but do not match those of Carp Brand Tufnol.

Applications:

Typical uses include small machined parts such as spacers, gears, rotor blades.

Availability:

Typical Sheet Size (mm):  1200x1200
