Informazioni tecniche
Review the product positioning, core data, compression behavior, application fit, and supply direction for SA700-400 foamed silicone rubber.
Q1
What is SA700-400 designed for?
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.
| Proprietà | Standard di prova | SA700-400 |
|---|---|---|
| Colore | Visivo | Gray / Black |
| Spessore (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% |
| Resistenza alla trazione | ASTM D3574-95 Test E | 260 kPa |
| Tear Strength | ASTM D3574-95 Test E | 3.3 N/mm |
| Conduttività termica | ASTM D5470 | ≤0.2 W/(m·K) |
| Tensione di guasto | ASTM D149 | ≥8 kV |
| Isolamento elettrico | 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.
