Technische Informationen

Review the product positioning, core data, compression behavior, application fit, and supply direction for SA700-300 foamed silicone rubber.

Q1

What is SA700-300 designed for?

SA700-300 is designed for applications that need stronger sealing force, higher compression resistance, and better structural support than softer foam grades, while still retaining foam conformability and environmental sealing capability.

Medium-Hard Sealing Direction

Suitable where the structure needs more sealing force and support than medium-soft or ultra-soft foam grades.

Higher Compression Resistance

Useful in battery and enclosure applications where stronger compression resistance is needed to control deformation or expansion.

Long-Term Performance Advantage

The datasheet states that its chemical composition and cellular structure provide long-term performance advantages.

Protection-Oriented Foam Use

Suitable for insulation, sealing, and cushioning roles in electrical, battery, and outdoor protection structures.

Q2

What are the core technical data for SA700-300?

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

These values are suitable for early-stage screening. Final selection should still be validated against the actual compression support requirement, gap size, sealing line, and environmental exposure condition.

Q3

What performance strengths does SA700-300 emphasize?

The datasheet points to higher compression resistance, stronger sealing support, exceptional thermal insulation, and electrical insulation as the core functional directions.

Higher Compression Resistance

Well suited to structures that need stronger support against deformation, including battery cell expansion scenarios.

Excellent Compression Resilience

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

Exceptional Thermal Insulation

Low thermal conductivity helps effectively prevent heat transfer in protected electrical and battery assemblies.

Electrical Protection

High insulation value and high breakdown voltage support battery packs, cabinets, and power-related protection structures.
