B12 phenolic cotton laminate (often referred to as F2 laminate due to the old British Standard) is a medium weave, general purpose fabric laminate. The material is manufactured from cotton fabric and phenolic resins that are layered and bonded to create a material that is developed for general purpose, less intricate mechanical applications. Attributes of B12 include; high strength, toughness, good resistance to wear and moderate electrical insulation properties at low voltages. This material is an alternative grade to TUFNOL® Whale Brand and TUFNOL® Crow Brand.
B12 displays a higher operating temperature than comparable plastic materials such as nylon, and a lighter weight than metal comparisons such as steel and aluminium. As a thermoset material, finished components are manufactured using similar techniques to plastic machining such as CNC milling, turning, sawing or drilling. See our machining services information for examples of our work.
B12 is manufactured to BS EN 60893 Standard: 3-4-PFCC201.
Applications
Pulleys and sheaves, coarse tooth gears, bolts and screws, rollers, bushes and spacers, welding jigs, scraper blades, wear components, insulating components, low voltage insulation, etc.
