Silicone Foam Rubber SA700-260

Silicone Foam Rubber SA700-260

SA700-260 is a medium-soft silicone foam that is harder and denser than SA700-200 while still retaining low closure force and conformability. It is designed for assemblies that need improved sealing performance, stronger compression support, and long-term durability in cushioning, insulation, and environmental sealing applications.

Key Benefits

  • Medium-soft foam structure with improved sealing performance compared with softer SA700-200 material
  • Retains low closure force and conformability while offering higher compression resistance
  • Exceptional thermal insulation with low thermal conductivity to reduce heat transfer
  • Excellent compression resilience for long-term sealing performance with low compression set
  • Strong electrical insulation for protected electrical and battery-related assemblies
  • UL94 V0 flame-retardant performance for safety-focused sealing applications

Technical Information

Review the product positioning, core data, compression behavior, application fit, and supply direction for SA700-260 foamed silicone rubber.

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.

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.
