Moisture ingress in electrical cable connections may not cause immediate failure — but over time it seriously threatens insulation integrity, conductor condition, and system safety. How Does Moisture Damage Cable Insulation? 1. Corrosion at Conductor Surfaces Moisture causes oxidation and corrosion at copper or aluminium surfaces. The oxide layer increases contact resistance → heating, transmission […]

NCflex PBD W-25 is a two-component elastic insulation resin based on polybutadiene (PBD) chemistry. Unlike rigid polyurethane or epoxy systems, NCflex does not form a hard structure after curing. Instead, it produces a low-modulus, elastic, and hand-removable protective mass. NCflex vs Rigid Polyurethane Criterion NCflex Rigid PU System Cured structure Elastic, low-modulus Hard, rigid Service […]

Technical Guide IP67 and IP68 Explained: Electrical Insulation Protection Ratings IP67 and IP68 are among the most frequently referenced protection ratings in electrical insulation, cable joint protection and junction box encapsulation. Understanding the difference between these ratings is important when selecting the right potting resin, re-enterable insulation system or silicone gel solution for field applications. […]

Electric vehicle (EV) and renewable energy systems present more demanding insulation resin requirements than conventional electrical applications. High voltage, wide temperature ranges, vibration, moisture exposure, and long service life expectations — all of these factors make correct resin system selection critical. Why Is Insulation Resin Critical in EV Systems? Compared to conventional vehicle electronics, EV […]
