Tufnol® Industrial Laminates

Tufnol® Industrial Laminates



Tufnol® industrial laminates are constructed from layers of fibrous reinforcement, such as cotton, paper or glass fabric bonded together with high quality thermosetting resins. Tufnol® industrial laminates are available in various grades and has been developed for a wide range of applications including electrical transformers, gears, bearings, jigs and fixtures. We can also offer machined Tufnol® components using a wide range of CNC facilities. Quotations can be provided from either existing samples or drawings.

Key Features: Rigid with high strength and low weight. Excellent electrical and thermal insulation properties. Non-corrosive and can reduce corrosion in metal parts. Higher thermal expansion than many metals. Easily machined to produce finished components. Rigid and stronger under flexural, tensile and compressive forces than most engineering thermoplastics. Resistant to heavy loads with minimal creep giving load bearing characteristics superior to thermoplastic materials. Excellent weather resistance. Good resistance to chemicals, oils, solvents and hydrocarbons. Concentrated acids and alkalis will attack laminates.

Temperature: 0°C up to +250°C

Applications: Gears, bearings, jigs and fixtures.


We offer Tufnol® industrial laminates in sheet, rod, tube, or machined to suit your requirement. Please select the grade you require from the links below. Alternative grades are also available.
