 Antifriction graphite-fluoroplastic materials


AMC-1 grade material
Is used for the blocks of dry friction in gases with normal humidity as well as for the blocks of liquid friction in oil products and liquefied gases: edge thickenings separating such media as oil-gas, kerosene-air; piston rings operating without lubricant in the working cylinders of compressors; for thickening air-fractionating friction blocks cigarette-making machines and so on.
It is not allowed to be applied in direct contact with food products.

For the parts made of AMC-1 material it is recommended to use cast iron and steel as the countershank material with Rockwell hardness of not less than 40-50 and smoothness - N 9-N 12. Permissible working temperature of products made of AMC-1 material should be within the limit of Ц60 to +200∞ C. It is not allowed to apply products made of AMC-1 material in direct contact with food products.
