BELPA CSA 520 PRESSED CARDBOARD
- The Belpa CSA 520 pressed cardboard sheet is manufactured with the latest advances in fibers with high thermal and mechanical resistance mixed with a high quality NBR rubber matrix.
- The compressed cardboard thus obtained is a cardboard sheet for joints with high mechanical and thermal resistance, very low gas permeability and high residual stress, complying with the BS 7531 grade X qualification standard.
- Belpa CSA-520 cardboard is used for most industrial services, with excellent hot flow making the product the ideal solution for a multitude of services and equipment.
- Certifications:
- DVGW (DIN 3535-6 Gas)
- WRAS (BS6920 Drinking Water)
- TZW (KTW Drinking Water)
- TA LUFT (VDI 2440 minimum leakage at 250ºC)
