GLASS SYNTACTIC POLYURETHANE

• Polyurethane (PU) based subsea wet insulation system filled with hollow glass microspheres (HGMS)
• HGMS is a 3M product made from silica glass in the form of 30-micron diameter spheres. HGMS improve resistance to heat flow within the PU matrix and are resistant to extreme crushing forces found at subsea water depths
• PU systems for subsea applications are formulated to resist chemical breakdown in hot and wet service conditions. We use Dow HYPERLAST™, and also other products.
• GSPU is a reaction injection molding
• (RIM) product. PU components and HGMS are blended and injected into steel molds that surround the pipe’s outer surface
• GSPU delivers excellent thermal insulation, adhesion, impact strength, and durability across a broad spectrum of demanding installation and operating conditions
• GSPU facility boasts an industry-leading molding process, significantly reducing the risk of costly quality issues during installation and field joint operations
