Engineered Syntactic Systems BZ-28

Engineered Syntactic Systems BZ-28 is a premium syntactic foams safely operates in the oceans Bathypelagic Zone, at depths ranging from 1,000 down to 4,000 meters. These specially formulated composites utilize a variety of hollow glass spheres to attain the lowest density in the industry. Hydrostatic performance is assured with crush depths at a minimum of 1.5 times the operation depth. BZ 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.
