HYSF Subsea Specializes in Hydrolysis-Resistant Overmolded Cable Assemblies
HYSF Subsea provides specialized underwater cable assemblies and molded harnesses utilizing hydrolysis-resistant polymers for critical marine applications. The company's overmolding process uses high-grade Polyurethane (PU) and Neoprene to create a true chemical bond between the cable jacket and connector body .
Key Technologies:
Void-free molecular bonding with advanced vacuum-degassing
Anti-capillary protection preventing water migration through cable strands
Hydrolysis-resistant polymers that resist chemical breakdown and swelling during long-term saltwater immersion
High-pressure integrity at depths up to 6,000m
Material Advantages:
PU and Neoprene outer jackets offer the best balance of flexibility and ruggedness
Exceptional resistance to hydrolysis, UV radiation, oil, and microbial attack
Service life of 10+ years in demanding subsea environments
Applications: Towed arrays, dynamic ROV tethers, and equipment subjected to seabed abrasion or reef contact .
