LAMITEX® laminates:

For engineering applications throughout industry, LAMITEX® laminated materials provide a unique range of design benefits. LAMITEX® laminates are engineering materials made from layers of fibrous reinforcement such as cotton cloth, paper or woven glass cloth, which are bonded together with high quality plastics resins. The layers are pressed together under high pressure and the resin is baked until it becomes solid, fusing the material into a tough, strong and dense material.

By using different resins, such as phenolic, epoxy or melamine, with different reinforcements of paper, cloth or felts, a range of grades is created with types to suit a wide variety of applications.

photoLAMITEX® laminates combine mechanical strength and electrical insulation with chemical and weather resistance. They are rigid, with a high strength to weight ratio. They can be machined on standard machine tools to make finished components.

Franklin offers a comprehensive range of grades for many different purposes. To obtain the best results, it is important to use the right grade from the LAMITEX® range to suit the application.

Phenolic paper grades are most commonly used for rigid electrical insulation for items such as electrical panels and boards, tag strips, insulating sleeves and many similar components. They are not usually used where demanding mechanical duties are involved, although the lower cost grades are excellent value as rigid non-metallic materials. The most widely used grades are Grade XXX (high electrical) and Grade XP/XPC (low-cost commercial grade).

Epoxy paper and cotton grades are chosen when outstanding electrical properties are needed, particularly for their surface electrical insulation resistance properties.

Glass fabric grades are made from a variety of resin types with differing temperature resistance, electrical properties and flammability. They are sophisticated materials with very high strength properties and are used for many different electrical, mechanical and cryogenic purposes in the most demanding applications.

Phenolic cotton gradesare widely used for mechanical applications requiring high strength and toughness with excellent wear resistance. They are used for a multitude of different components such as gears, bearings, rollers, cams, support plates, insulating wear pads, scraper blades and piston rings. Fine weave cloth grades are strongest and are better for more intricate components. Coarser weave grades are used for larger and more rugged components. The most popular types are L/LE (fine weave) and C/CE (general purpose medium weave). CB/LB graphite impregnated are popular for bearings.

Polyester glass mat materials have excellent electrical properties with good rigidity and temperature resistance. They are often used in electrical equipment, particularly where higher temperatures occur, for items such as electrical panels, busbar supports, switchgear, phase barriers and arc shields.
