RTI certification refers to long-term temperature resistance. Within the case of polyurethanes, that is often a most of 130° C.

Among the many newest merchandise to obtain UL certification is WEVOPUR 60416 FL. A 12-month testing program confirmed an RTI of 160° C. The product has a thermal conductivity of 1.6 W/mK, making it appropriate to be used within the stators of electrical motors, in addition to inductive elements akin to chokes and transformers. 

Wevo’s WEVOPOX 36001 FL epoxy resin, together with the hardener WEVODUR 5001, has been licensed to UL 94 V-0 for an utility thickness of two mm.

The brand new polyurethane- and epoxy-based Wevo options are designed to be used in electrical elements which can be operated constantly at larger temperatures and require flame retardancy. These embody transformers, chokes and sensors for electrical functions, in addition to energy electronics elements akin to charging plugs, on-board chargers and EV motors.
