novaphit® SSTC
novaphit® SSTC is a thermally expanded graphite material, reinforced with expanded acid-resistant stainless steel (1.4404). A special type of reinforcement provides better compressibility and recoverability of the material, a decrease in gas permeability in comparison with materials reinforced with smooth or perforated sheet metal. In production, special heat-resistant graphite with a low oxidation is used, which ensures durable and reliable operation of the seal at high temperatures and cyclic loads.
novaphit® SSTCTA-L is a material specially designed for industries with rigorous requirements for gas permeability at high temperatures and pressures. Classified as high quality sealing material according to VDI 2440 and TA Luft test criteria.
