EMI 1320 Silicone Sponge Tape
EMI 1320 Silicone Sponge Tape is a medium-density, closed-cell expanded silicone sponge tape engineered for high-performance gasketing, insulation, and cushioning in demanding environments. Known for its durability and resistance to temperature extremes, UV, ozone, and solvents, EMI 1320 provides reliable sealing and protection in both industrial and food-contact applications. Its excellent compression set resistance and flame-retardant properties make it well-suited for aerospace, electronics, and environmental sealing tasks.
Applications include: High temperature gaskets, flame retardant cushions, solvent resistant weather seals, and food contact applications.
- Ideal for high temperature gasketing, flame-retardant cushioning, and weather sealing
