Laminates

Industrial laminates are made by applying heat and pressure to layers of paper, canvas, linen or glass cloth impregnated with synthetic thermosetting resins. These materials are called ‘Thermosets’. A variety of of resin types and cloth materials can be used to manufacture thermoset laminates with a range of mechanical, thermal and electrical properties.

SRBF

SRBF (Synthetic Resin Bonded Fabric) is most commonly used in mechanical applications (Gears, Bearings, Jigs and Fixtures). It is available in a variety of grades with slightly different characteristics. Whale (F2 SRBF), Carp (F1 SRBF) and Bear (F2/1 SRBF) come from the Tufnol range. Whale is the general-purpose standard grade, while Bear is used where lower moisture absorption and greater strength is required for the application. Carp brand is used where a combination of good all-round electrical and mechanical performance is required. In addition to the Tufnol range we also stock equivalents and alternatives to the same British Standards.

SRBP Paper

SRBP (Synthetic Resin Bonded Paper) is available in a variety of grades, from commercial to high-spec grades in rod, sheet and tube. Applications can vary from backing and entry drilling boards, to high-voltage electrical insulators. P3 (Tufnol Kite brand) is available from stock in sheet and tube form and Swan brand is available in rod. Other grades can be recommended for specific applications.

Epoxy Glass Laminates

These epoxy glass laminates are specified for their high strength and high dimensional stability over temperature. They can be used for terminal boards, high humidity applications, electrical and electronic test equipment and electric rotor insulation. G10 and G11 are difficult to cut and machine and may require special equipment, G10 is the stronger, G11 is a better insulator and can take higher temperatures. 4W/EP (FR-4) is a fire-retardant G10 used primarily in the printed circuit board industry.
