• 1. Metal core sheet: Material: SPCC cold rolled steel sheet (0.15~0.25mm). Provides strength and deformation resistance.
• 2. Interface Bonding Layer: Primer for superior adhesion.
• 3. Elastic layer: Material: NBR. Forms: high foaming, low foaming, non-foaming, fiber reinforced. Functions: sealing, compression, sound absorption, vibration reduction, heat insulation.
• 4. Anti-stick treatment: Surface finish to prevent bonding.

• Pretreatment: Rust removal, cleaning, activation, and application of surface treatment agent.
• Refining: Compounding, masticating, and mixing for performance quality.
• Composite: Coating process of rubber and metal core board.
• Vulcanization: Utilizing drying tunnels and ovens for curing.

The metal foam rubber composite sealing material offers excellent compression resilience and creep relaxation resistance. It features outstanding oil and gas sealing performance, replacing traditional cork and asbestos-free materials in engines and sewing machines.
