Silicone Strips
Extruded solid and closed-cell sponge silicone strips designed for high-temperature sealing, electrical insulation, and anti-vibration damping. Available plain or laminated with high-temperature acrylic or silicone pressure-sensitive adhesive (PSA) tape.
Types & Configurations of Silicone Strips
High-Temperature Adhesive Silicone Strips
Pre-applied silicone adhesive tape withstanding up to +200°C without peeling or melting.
Closed-Cell Silicone Sponge Strips
Low-compression-set cellular silicone strips sealing irregular surfaces with light latch force.
Translucent Solid Silicone Packing Strips
High-purity clear silicone strips for architectural structural glazing and cleanrooms.
Flame-Retardant Silicone Strips (UL 94 V-0)
Low-smoke, low-toxicity silicone meeting EN 45545-2 railway transit standards.
Electrically Conductive Silicone Strips
Metal-particle loaded silicone strips providing RF/EMI shielding and static discharge.
