The data listed are reference values and may vary depending on the processing method and sample. Thesedata cannot be simply applied to finished products. The suitability of materials for specific purposes should beinspected by the manufacturer and the user.2. These technical parameters are only used as assistance during planning. They particularly do not represent promises of performance.3. “ ” is tolerable, “-” is not tolerable, and “0” depends on the situation.Main characteristics of formaldehyde rods(1). High mechanical strength, high rigidity and high hardness. (2).Good sliding property and wear resistance. (3).Good creep resistance and excellent dimensional stability. (4).Physiological inertness, suitable for contact with food. (5).Low impact strength, poor acid resistance and weather resistance. (6).Machinable by machine tools and weldable. (7). Can be used within the temperature range of -50 to 105 ℃.Product application fieldsIt is widely used in the manufacturing of sliding and rotating machinery, such as small modulus gears, cams,bearings, bushings, valve seats,shafts, impellers, blades, etc. The application industries cover automotive,electronic and electrical, medical, mechanical and other fields.
