NewMet Limited HT606A-3.2X19 (10-Mtr-LG)

Additional Product Information

Overview

HT603A and HT606A are high-performance silicone foams designed for critical aviation, MRO, and industrial applications. HT603A is a low-density, fire-retardant silicone foam, while HT606A adds an AD adhesive backing for easy installation. These foams provide exceptional thermal resistance, environmental durability, and mechanical reliability, making them trusted by teams for sealing, insulation, and vibration damping in aircraft, automotive, mass transit, and electronics systems.
