Description
Tufnol Whale Sheet is a high-strength, rigid material made from cotton and phenolic resin. Ideal for mechanical engineering applications and low voltage insulation.
Material Composition
Tufnol Whale Sheet is constructed from medium weave cotton and phenolic resin, forming a synthetic resin bonded fabric. This combination results in a material that is dimensionally stable and suitable for various mechanical engineering applications.
Mechanical and Thermal Properties
The sheet has a density of 1.36 g/cm³, tensile strength of 68 MPa, and compressive strength of 310 MPa when flatwise. It can withstand continuous temperatures up to 120°C and intermittent temperatures up to 130°C.
Applications and Uses
Tufnol Whale Sheet is widely used for components such as bearings, bushes, spacers, and jigs. It is particularly effective in low voltage applications due to its excellent electrical insulation properties.
Advantages and Limitations
This material boasts high strength, low weight, and excellent resistance to chemicals and weathering. However, it is not suitable for high voltage applications and can generate fine dust when machined.
