Feroform PR12

The Feroform range of materials has been developed by Tenmat to offer the design engineer the chance of replacing metal-based materials with unique, non-asbestos, wearing and bearing composites capable of duplicating and, in some cases, exceeding the performance of asbestos composites. Feroform materials possess strength, durability dimensional stability and excellent wear characteristics besides exhibiting good resistance to attack by many chemicals.

The resins used have been selected for their good mechanical properties and high thermal and dimensional stability. Both organic and synthetic fibres employed for reinforcement of the resins have been selected from the many types available for their high modulus and stability in water and various chemicals.

The “F” Grade range is primarily used in dry applications whilst the “T” & “PR” Grades have been specifically designed with very low water and moisture absorption, making them ideal for use in submerged applications yet still suitable to use dry.

The addition of selected friction modifiers, such as PTFE, graphite and molybdenum disulphide, enhances the wear properties and life of the materials, enabling them to be operated at higher speeds and loads.


Like the PR14 grade but has molybdenum disulphide impregnated evenly throughout the material for lower co-efficient of friction. With high load and low friction properties, coupled with excellent wear performance make this grade ideal for larger equipment where greater working pressure and shock loads can be expected.
