Polyurethane Resin Material
1. A Shore hardness of 90±5 provides mechanical protection as well as elasticity that make it easy to use in cable joints subject to temperature changes and mechanical stress. 2. With a volume resistivity >1.0×10¹³ Ω·cm, dielectric strength >20 kV/mm, and water absorption <0.2%, it provides both electrical insulation and moisture protection. 3. Because the resin is easy to flow and its gel time ranges from 15 to 25 minutes, it is quite simple to fill cable joints and intricate electrical structures with it.
