HZ Grade Microsphere Syntactic Foam

PREMIUM PERFORMANCE
HZ Grade syntactics are formulated to survive crush pressures greater than 20 000 psi for safe operation in the Hadal Zone. Produced from the most advanced resin and hollow glass microspheres available today, these homogeneous materials provide the industry’s lowest density for any given depth.

INDUSTRY APPLICATIONS
Ultra-buoyant HZ Grade materials are predominantly used for deep water AUV, ROV and HOV applications, where reliable performance, increased payload and longer mission duration at extreme depths are critical for successful operation.

PRODUCT AVAILABILITY
HZ Grade syntactic foams are available in block form and may be readily used for customer assembly or cut to fit application requirements. Blocks or trimmed parts may also be bonded together to form larger structures. Standard block size is 4” x 12” x 24”, but custom sizes and shapes are available upon request.
