Electronic, electric and electrotechnical sectors include applications for high/low voltage, press work of insulators and encapsulation of high voltage transformers, applications in the sector of cables for energy transmission and telecommunications. This sector requires formulations characterized by excellent chemical, mechinical and electric resistance completely insulating toward water and moisture (dump, humidity).
Polyurethane and epoxy systems are suitable to be used in this sector.
Resins for electric and electrical insulation (insulating resin) encapsulating, insulator.
Polyurethane resins offer flexibility, elasticity and abrasion resistance. Polyurethane resins for electrical insulation are appreciated for the rapid hardening and the low exothermic reaction. Special polyurethane formulations are particularly interesting for the flexibility also at very low temperatures, low electric constant, transparence and UV stability.
Epoxy resins, offer generally a higher temperature resistance and lower shrinkages than polyurethane resins for electrics. They can be more hard then polyurethane resins, stronger and with a better adhesive power, they have a higher chemical resistance and can be self extinguishing. Encapsulation for an electrical connettor.
