Syntactic Foam Blocks
A wide range of densities for each depth and requirement down to very deepwater.
Standards Blocks
BMTI delivers a full range of advanced epoxy-based syntactic foams engineered for critical subsea operations—from subsea vehicles to permanent deepwater structures.
Designed for use at depths up to 12,000 meters, BMTI’s materials combine low density, high mechanical strength, and long-term reliability under extreme pressure and environmental conditions.

Insulation Foam Blocks
BMTI advanced insulation materials are designed to operate reliably at depths up to 4,000 meters and withstand service temperatures up to 140°C, making them ideal for deepwater flow assurance and subsea thermal insulation applications:
- High glass transition temperature (Tg 110°C to 140°C) for structural integrity under heat
- Excellent thermal stability under high hydrostatic pressure
- High compressive strength
- Superior hot-wet resistance, preventing water ingress and thermal degradation
- Optimized for use with composite layers
High Thermal Grade
density tolerance from ±20 kg/m3
Fire Resistant Grade
density tolerance from ±40 kg/m3
