Marine Flange Non-Asbestos Sheet - Seawater & Salt Spray Resistant, IMO Compliant For Marine Diesel Engines

Available in thickness options from 0.5mm to 5.0mm, our advanced sealing materials adhere to marine engineering specifications. For optimal performance, we recommend selecting the minimum thickness suitable for your operational requirements.

Technical Composition & Performance:
Our engineered composite sheets combine aramid polymer reinforcements with nitrile rubber compounds, delivering exceptional chemical stability. These multilayer laminates demonstrate:
• Superior resistance to petroleum-based fluids and hydrocarbon fuels
• Reliable performance across aqueous media including seawater immersion
• Compatibility with compressed gases and LNG/LPG applications
Certified for deployment in marine propulsion systems, coastal power plants, and offshore drilling equipment.

Manufacturing Specifications:
Formulated through precision hot-roll compression and vulcanization processes using:

• Aramid fiber matrix

• Synthetic elastomer binders

• Mineral reinforcement particulates

• Polymer stabilizers

Temperature Grading System:
Three performance classifications (maximum continuous service temperatures):
CSNXB150: 150°C operational limit
CSNXB250: 250°C thermal threshold
CSNXB350: 350°C extreme heat rating

Key Advantages:
• Enhanced compression recovery maintains seal integrity under vibration
• Delamination-resistant layered construction
• Cost-effective alternative to metallic sealing solutions
• Full compliance with IMO MSC.282(86) regulations
• UKAS-accredited ISO 9001 manufacturing certification
• Asbestos-free composition verified through SGS testing

Marine Engineering Applications:
