Rods according to DIN 7335 Hgw 2088 (PF CC 42), plates to DIN 7335 Hgw 2082 (PF CC 201) NEMA „C” and tubes to DIN 7335 Hgw 2085 (PF CC 22) are produced. Cresol formaldehyde resin reinforced with textile fabric. It has the average characteristics described as fabric-filled phenolics, the stress mark from the molding instrument is visible on the outer diameter on the rods and tubes, therefore it has to be always machined to ensure circularity.
