Q1### What is SA700-260 designed for?

SA700-260 is designed for sealing and cushioning applications that need more support and stronger sealing force than SA700-200, while still keeping soft conformability and relatively low closure force.

**Medium-Soft Sealing Direction**Suitable where the design needs stronger sealing support than ultra-soft foam grades.

**Improved Compression Support**Higher density and harder feel help resist battery cell expansion and maintain interface support.

**Long-Term Seal Stability**Patented chemical composition and cell structure are presented as supporting long-term performance.

**Protection-Oriented Foam Use**Well suited for structures requiring both sealing and insulation in electrical or battery-related environments.

Q2### What are the core technical data for SA700-260?

The datasheet provides the following values for evaluating material firmness, insulating capability, and flame-retardant performance.

| プロパティ | Test Standard | SA700-260 |
| --- | --- | --- |
| カラー | ビジュアル | Gray / Black |
| 厚さ（mm） | / | 1.0–10.0 |
| Density (kg/m³) | ASTM D3574-95 | 260 ± 26 |
| Compression Force Deflection (25%) | ASTM D3574 | 8 kPa |
| Compression Set | ASTM D3574-95 Test D @ 158°F | <5% |
| 引張強度 | ASTM D3574-95 Test E | 180 kPa |
| Tear Strength | ASTM D3574-95 Test E | 2.8 N/mm |
| 熱伝導率 | ASTM D5470 | ≤0.2 W/(m·K) |
| 絶縁破壊電圧 | ASTM D149 | ≥8 kV |
| 電気絶縁 | ASTM D412 | >1 × 1016 Ω・cm |
| Flame Retardancy | UL94 | V0 |

These values are suitable for early-stage screening. Final material selection should still be validated against the actual gap, compression target, sealing line, and environmental durability requirement.

Q3### What performance strengths does SA700-260 emphasize?

The datasheet points to stronger sealing support, excellent thermal insulation, long-term compression resilience, and electrical insulation as the key functional directions.

**Enhanced Sealing Performance**Compared with SA700-200, it is positioned to deliver stronger sealing force and higher compression resistance.

**Excellent Compression Resilience**Compression set below 5% supports long-term sealing effect and resistance to permanent deformation.

**Thermal Insulation**Low thermal conductivity helps reduce heat transfer in protected electrical and battery structures.

**Electrical Protection**High insulation value and high breakdown voltage support protected power-system and enclosure designs.

Q4### How can SA700-260 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  
ダイカット製品カスタマイズ

**Storage & Transportation**Store in a well-ventilated, cool, and dry place. Keep away from open flames.

**Safety**The product is described as non-toxic and to be stored and transported as a non-hazardous material.

**Project Notes**Confirm actual compression support requirement, gap size, sealing target, and outdoor exposure conditions before sampling.

Q5### Which applications fit SA700-260 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 pad structures where higher compression support is needed.

#### Upper / Lower Housing Sealing Strips

Applicable to enclosure sealing strips that need stronger sealing force and good aging resistance.

#### Outdoor Communication / Power Cabinets

Suitable for waterproof sealing strips exposed to sunlight, rain, and temperature fluctuations.

#### Charging Pile Fire Sealing

Can be used for fire sealing and protective sealing roles inside charging-pile structures.
