Flexible insulating paper obtained by hot bonding a polyester film to two 50 micron layers of non-wovwn polyester, securely bonded to the two faces of the film using special resins to increase resistance to thermal ageing. The surface of the DMD compound can be further impregnated to saturation taking the heat resistance to class F (155°C).
Class B 130° in continuous service
Class B/F 130/155° C
Melting point: 260° C
