Tufnol® Index

Phenolic Cotton Tufnol

Tufnol phenolic cotton materials are the workhorse grades of Tufnol for general mechanical applications. They are strong and tough with very good wear resistance and they are easy to machine into finished components. They are available with cotton fabric reinforcements ranging from fine weave to coarse. In general, the medium to coarse weave Tufnol grades are used for larger and more rugged components requiring good all round strength and toughness. The finer grades of Tufnol are chosen for their superior finish, higher dimensional stability and improved strength in thin sections.

Available Tufnol brands: Tufnol Whale, Tufnol Carp, Tufnol Crow  Available to buy in: sheet, rod and tube

Glass Fabric Tufnol

This group includes grades with wide ranging properties determined by the resins used to bond the laminations. All of these materials are characterised by very high strength properties, good temperature resistance and good dimensional stability. Due to their high glass fibre content they are not machined as readily as cotton or paper grades and are not normally suitable for applications involving wear. The range includes grades with exceptional temperature resistance, first class dielectric properties, good resistance to tracking, assessed flammability and superb structural strength and toughness. These materials are used in a very wide range of technically demanding applications.

Available brands: 10G/40, 10G/42, 6G/91 + others  Available to buy in: sheet, rod and tube

Phenolic Paper Tufnol

These materials are strong, rigid and very economical, with good electrical insulation properties. They are used in a very wide range of electrical installations and in equipment where rigid electrical insulation is required. The higher voltage and for greater electrical stability in conditions of varying humidity

Available brands: Kite, Heron, Swan  Available to buy in: sheet, rod and tube

Epoxy Cotton Tufnol

This grade is characterised by its excellent electrical properties, particularly the resistance of surface tracking and by low water absorption, good dimensional stability and a higher working temperature than its phenolic counterparts. In particular, the fine weave cotton fabric grade offers first class electrical properties with excellent wear resistance, a combination not found in other grades. This material gives components with a superb machined finish and it is used in many exacting wear applications, where very good dimensional stability is needed
