2841-W SMP immersion glass fiber reticulated knuckle-free bondage
1.General Information
This weftless tape is a kind of semi-curing reticulate material,which is composed of alkali-free glass fiber impregnated modified epoxy resin (or polyester resin),it appears reticulation when it's pulled apart laterally.
It has high impact resistance,high modules ,low stretching,no magnetic hysteresis, no trickle loss.Heat resistance classification is F.
It's suitable for motor stators,transformer core ,large-scale motor and generators,electric appliances etc.
