Información técnica
Review the product positioning, core data, compression behavior, application fit, and supply direction for SA700-450 foamed silicone rubber.
Q1
What is SA700-450 designed for?
SA700-450 is designed for enclosures and assemblies that need ultra-rigid silicone foam behavior, durable high-closure-force gaskets, stronger sealing performance, and long-term reliability under demanding environmental conditions.
Ultra-Rigid Foam Direction
Suitable where the structure requires more rigid gasket behavior than lower-density or softer foam grades.
Durable High-Closure-Force Gaskets
Useful in gasket applications that require durable sealing under higher compression force and long-term service.
Long-Term Performance
Its patented chemical composition and foam structure are presented as offering 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 SA700-450?
The datasheet provides the following values for evaluating rigid gasket support, sealing durability, insulating capability, and flame-retardant performance.
| Propiedad | Norma de ensayo | SA700-450 |
|---|---|---|
| Color | Visual | Gray / Black |
| Espesor (mm) | / | 1.0–10.0 |
| Density (kg/m³) | ASTM D3574-95 | 450 ± 45 |
| Compression Force Deflection (25%) | ASTM D3574 | 140–180 kPa |
| Compression Set | ASTM D3574-95 Test D @ 158°F | <5% |
| Resistencia a la tracción | ASTM D3574-95 Test E | 350 kPa |
| Tear Strength | ASTM D3574-95 Test E | 5.5 N/mm |
| Conductividad térmica | ASTM D5470 | ≤0.2 W/(m·K) |
| Tensión de ruptura | ASTM D149 | ≥9 kV |
| Aislamiento eléctrico | 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 SA700-450 emphasize?
The datasheet points to ultra-rigid gasket support, strong sealing durability, exceptional thermal insulation, and electrical insulation as the core functional directions.
Ultra-Rigid Gasket Support
Designed for durable, high-closure-force gasket structures rather than softer compression interfaces.
Excellent Compression Resilience
