RPU313 Re-Entrable Encapsulation

 RPU313A – RPU313B

 

Low viscosity polyurethane re-entrable casting resin system for encapsulation of  electrical and electronic equipment as well as telecommunication cabling. Flame retardant, almost self – extinguishing.

 

It’s possible to burn polyurethane safely, but it’s not trivial. If you burn it at low temperatures, you get hydrogen cyanide, and if you burn it (or, in air, anything) at high temperatures, you get deadly nitrogen dioxide instead.
