Q2
What are the core technical data for SA700-350?
The datasheet provides the following values for evaluating sealing support, compression resistance, insulating capability, and flame-retardant performance.
| Imóveis | Norma de ensaio | SA700-350 |
|---|---|---|
| Cor | Visual | 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 | 300 kPa |
| Tear Strength | ASTM D3574-95 Test E | 3.9 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 compression support requirement, sealing line, and long-term environmental exposure condition.
