SA700-400 is designed for enclosures and assemblies that need durable, high-closure-force gaskets, stronger sealing performance, and long-term reliability under demanding environmental conditions. **Rigid Foam Direction**Suitable where the structure needs rigid silicone foam behavior rather than softer conformable foam grades. **High-Closure-Force Gaskets**Useful in gasket applications that require durable sealing under higher compression force. **Long-Term Performance**Its patented chemical composition and cellular structure are presented as providing long-term performance advantages. **Protection-Oriented Foam Use**Suitable for insulation, sealing, cushioning, and protective roles in electrical, battery, and outdoor structures. Q2### What are the core technical data for SA700-400? The datasheet provides the following values for evaluating rigid gasket support, sealing durability, insulating capability, and flame-retardant performance. | Imóveis | Norma de ensaio | SA700-400 | | --- | --- | --- | | Cor | Visual | Gray / Black | | Espessura (mm) | / | 1.0–10.0 | | Density (kg/m³) | ASTM D3574-95 | 350 ± 35 | | Compression Force Deflection (25%) | ASTM D3574 | 110–140 kPa | | Compression Set | ASTM D3574-95 Test D @ 158°F | <5% | | Resistência à tração | ASTM D3574-95 Test E | 260 kPa | | Tear Strength | ASTM D3574-95 Test E | 3.3 N/mm | | Condutividade térmica | ASTM D5470 | ≤0.2 W/(m·K) | | Tensão de rutura | ASTM D149 | ≥8 kV | | Isolamento elétrico | ASTM D412 | >1 × 1015 Ω-cm | | Flame Retardancy | UL94 | V0 | These values are suitable for early-stage screening. Final material selection should still be validated against the actual gasket compression requirement, sealing line, and long-term environmental exposure condition. Q3### What performance strengths does SA700-400 emphasize? The datasheet points to rigid-gasket support, strong sealing durability, exceptional thermal insulation, and electrical insulation as the core functional directions. **Durable Gasket Support**Designed for durable, high-closure-force gasket structures rather than softer compression interfaces. **Excellent Compression Resilience**Compression set below 5% supports long-term sealing effect and resistance to permanent compression deformation. **Exceptional Thermal Insulation**Low thermal conductivity helps effectively prevent heat transfer in protected electrical and battery assemblies. **Electrical Protection**High insulation value and high breakdown voltage support battery packs, cabinets, and power-related protection structures. Q4### How can SA700-400 be supplied and handled? The datasheet provides a project-based supply direction with customized sheets and die-cut parts, plus standard storage and transportation guidance. **Configurations Available**Sheet products: Customized Die-cut products: Customized **Storage & Transportation**Store in a well-ventilated, cool, and dry place. Keep away from open flames. **Safety**O produto não é tóxico e deve ser armazenado e transportado como um material não perigoso. **Prazo de validade**12 meses Q5### Which applications fit SA700-400 best? The datasheet highlights battery pack structures, outdoor communication or power cabinets, and charging-pile sealing as strong-fit applications. #### Battery Pack Inter-Cell Pads Suitable for inter-cell cushioning and insulating pads where high compression resistance is required to help prevent battery cell expansion. #### Upper / Lower Housing Sealing Strips Applicable to enclosure sealing strips that need durable, high-force gasket behavior, flame retardancy, and aging resistance. #### Outdoor Communication / Power Cabinets Suitable for waterproof sealing strips exposed to long-term sunlight, rain, and temperature fluctuations without degradation in sealing force. #### Charging Pile Fire Sealing Can be used for fire sealing and protective sealing roles inside charging-pile structures. ### Transferências e FAQ Technical Resources [Download SA700-400 Datasheet](https://www.sheenmaterials.com/wp-content/uploads/2026/04/SA700-400-Datasheet-Sheen-Materials-Foamed-Silicone-Rubber.pdf) [View Datasheet Center](https://www.sheenmaterials.com/pt/resource/datasheet-download/) [Contact Sales for Sample Support](/cdn-cgi/l/email-protection#8af9ebe6eff9b9caffa7f9e2efefe4a4e9e5e7) Frequently Asked Questions Q1.
