This article reports on tests made of the resistance to the action of chemical media and increased temperatures of graphite reinforced plastics based on a furan oligomer of difurfurylidenacetone, an extruded mixture of difurfurylidenacetone with SF-010 phenylformaldehyde resin, and 2FA-D furfural-acetone oligomer of types DG-2(1), DFG-4K, and DG-3. The chemical resistance of the graphite reinforced plastics was tested in media of mineral and organic acids, salt solutions, and solutions imitating food industry media at temperatures of 23-100/sup 0/C, which made it possible to compare the chemical resistance of these materials and to make recommendations concerning their use. It is determined that the examined graphite reinforced plastics possess better resistance than ATM-1 and ATM-1T graphite reinforced plastics in increased concentration acid solutions and in sodium hydroxide solutions both at normal and at increased temperatures and may be used in place of phenolformaldehyde resin base graphite reinforced plastics (ATM-1, ATM-1T) and scarce special steels and nonferrous metals.
