TUFFAK WG polycarbonate sheet Fabrication guidelines Cutting A circular saw blade with carbide teeth utilizing the triple chip tooth design is the preferred method of cutting TUFFAK WG polycarbonate sheet. Table or overhead panel saws are normally
used. Circular saws should be run in the speed range of 6000-8000 ftmin. Blades for cutting 332 and thicker material should have 3-5 teeth per inch. The hook or rake angle should be 10-15. Cautions The following are suggested guidelines or concerns regarding machining working with TUFFAK WG polycarbonate sheet or any other engineering plastics. 1. Thermal expansion is up to 10 times greater with plastics than metals 2. Plastics will lose heat more slowly than metals 3. Avoid localized overheating 4. Softeningmelting temperatures of plastics are much lower than metals Regulatory code compliance and certifications Polycarbonate sheet classification A-A-59502 Type 1 Class 1 Polycarbonate resin classification ASTM D 3935 PC0116 Flammability - Plastic component UL 94 UL File E87887 These suggestions and data are based on information we believe to be reliable.
