1. Maximum temperature resistantof insulation : 200 C degree
2. Best continuous working temperature as 150C degree, max temperature as 230C degree momentarily.
3. Power deviation : 8% insulation resistance : >= 5MΩ
4. Compressive strength : 1500V/5s
5. Fast heat diffusion , uniform heat transfer , directly heat objects on ; high thermal efficiency , high strength , long service life ,work safe , uneasy for ageing.
