Class F DMDM Four-ply Flexible Laminates

Description:

Class F DMDM Flexible Laminates (equivalent to Voltaflex ® F6646) is a four-ply flexible laminates consisting of polyester nonwoven-polyester film-polyester nonwoven-polyester film (DMDM). It has excellent electrical and mechanical properties and high thermal resistance.

Application:

Class F DMDM is mainly used as slot liner, slot closure, phase and turn-to-turn insulation in electrical motors. It can be also used as interlayer insulation in transformers and other electrical machines and appliances.
