Feroform PR14

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.


Using a polyester resin matrix reinforced with woven synthetic cloth makes PR14 a cost effective general purpose grade to complement the existing Feroform range. Whilst the PR14 does not contain any friction modifiers it is still suitable in applications of high load and can be submerged in water.
