Why Static Control Matters
In sensitive electronics, medical devices, or cleanrooms, static discharge (ESD) can:
🔥 Destroy microchips • Disrupt instrumentation • Ignite flammable environments
Advantages of anti-static silicone sponge
✅ Permanent ESD Protection: Surface resistivity maintained 107–1010 Ω/sq (ASTM D257) non-migratory.
✅ Broad Thermal Stability: Operates continuously from -60°C up to 250°C without degradation.
✅ Low Compression Set: Under 5% deformation ensures long-term industrial sealing integrity.
Advantages of silicone sponge
✅ Sound Insulation:
✅ Long life service
✅ Sheets, tapes, gaskets, die-cut parts – tailored to your design
✅ Chemical stability： resists moisture, chemicals & particulates
