Tufnol Laminates - NEMA Equivalents Spider Diagram

Tufnol Laminate Grades Explained by Application and Reinforcement
(with NEMA equivalents)

Tufnol laminate grades are grouped by their primary reinforcement material and performance characteristics:

Paper laminates are predominantly used for electrical applications where good insulation, low smoke emission and cost efficiency are required. These grades include economical commercial options, flame-retardant paper laminates and specialist electrical grades designed for humid or high-spec environments.

Cotton fabric laminates are widely used for mechanical applications due to their excellent machinability, impact resistance and bearing performance. Available in fine, medium and coarse weaves, these grades are suited to gears, wear pads, bearings and structural components. Specialist bearing and PTFE-enhanced grades offer improved wear resistance and reduced friction.

Glass fabric laminates are designed for high-performance applications requiring superior strength, dimensional stability and resistance to elevated temperatures. These epoxy, silicone and polyimide-based grades provide outstanding performance in high-temperature, flame-retardant and chemically demanding conditions.

By mapping each laminate grade to its equivalent NEMA specification, the diagram simplifies material selection and ensures compliance with international standards across electrical, mechanical and high-temperature applications.
