In EV battery packs, outdoor telecommunication base stations, and high-precision instruments, components must endure not only thermal stress but also long-term mechanical vibration. Silicone Foam Pads offer unmatched low compression set and superior buffering through their unique cell-level micro-porous structure.
Material Science: Closed-Cell Architecture and Compression Mechanics The physical superiority of silicone foam originates from its internal gas-solid two-phase composite system:
Microcellular Structure and Compression Force Deflection (CFD): Silicone foam is filled with uniform closed-cells. When compressed, the trapped gas acts as a micro-airbag, providing excellent energy absorption. CFD is defined as: CFD = F / A (Pure text: CFD = F / A, where F is the force required to achieve a specific deformation, and A is the surface area) Lixing’s technology controls density between 0.15 and 0.50 g/cm3, maintaining high resilience at minimal weight.
Low Compression Set: Thickness recovery after long-term stress is the benchmark for quality gaskets. The cross-linked siloxane network ensures minimal permanent deformation even at 150°C. C = ((t0 – t1) / (t0 – ts)) * 100 (Pure text: C = ((Initial thickness – Recovered thickness) / (Initial thickness – Spacer thickness)) * 100)
Thermal Insulation and Flame Retardancy: The foamed structure significantly reduces thermal conductivity. Lixing’s products achieve UL94-V0 flame retardancy, critical for safety in high-voltage environments.
Industrial Applications
EV Battery Pack Sealing: Provides stress buffering between cells and seals out moisture to maintain IP67/IP68 ratings.
Telecommunication Enclosures: Ensures long-term sealing integrity under UV exposure and mechanical vibration.
