NewMet Ltd HT606A-3X9 (10-Mtr)

Additional Product Information

Overview

NEWMET SILICONES HT603A and HT606A are high-performance silicone foams designed for critical aviation, MRO, and aerospace applications. HT603A is a low-density, fire-retardant foam, while HT606A is adhesive-backed for easy installation. These foams are relied upon for insulation, vibration damping, sealing, and fire protection, providing teams with consistent reliability under extreme conditions.
