Sheet Insulations - EPLY

Eply EP - 50
A 2-ply (duplex) laminate of calendared cotton based press paper and 50 micron Polyester (PET) film.

Class B 130 C
o
Technical Description
The Eply EP-50 range of flexible, two ply electrical insulation materials are produced by laminating various thicknesses of cotton
based Presspan 3040 (grey-green in colour) using a thermally stable adhesive resin as the bonding agent. The Presspan 3040 has
excellent flexibility properties and crease resistance compared to Kraft based electrical papers and the application of the PET film
to the Presspan enhances the ease of insertion into slot windings. Eply EP-50 will slowly embrittle at temperatures over 100 C, but
o
can withstand short term temperatures of up to 150 C and as a result is very suitable for use in electrical devices rated at Class B
o
o
(130 C) temperature rise.
Applications
Eply EP-50 is widely used as a slot and slot closure insulation in a wide range of electric motors rated at Class B temperature rise.
Eply EP-50 also finds use as a slot and barrier insulation in vehicle electric’s, lighting ballasts, portable tools and domestic
appliances.
Eply EP-50 laminates have excellent flexibility, tensile strength and tear resistance and are very suitable for automatic punching,
forming and insertion processes.

Eply DMD
A 3-ply (triplex) laminate of non woven Polyester (PETP) fibres on either side of Polyester (PET) film.
Class F 155 C
o
Technical Description
The Eply DMD range of flexible insulation composite materials are produced by laminating various thicknesses of non woven
Polyester (PETP) fibres between Polyester (PET) film using a thermally stable adhesive resin as the bonding agent. Eply DMD
laminates are often used in the manufacture and repair of Class F rated AC induction motors, which operate continuously at
approximately 20 C below their rated temperature rise. Eply DMD will offer adequate thermal performance for such machines.
o
Applications
Eply DMD flexible laminates are widely used as slot and slot closure insulation in electric motors and alternators rated up to Class
F temperature rise. They are also widely used in air cooled transformers and portable tools. Eply DMD composites have sufficient
flexibility, tensile strength and tear resistance to make them suitable for easy forming, punching and insertion by automated
machinery.

Eply NMN and NMN NC
A 3-ply (triplex) laminate of calendared Nomex® polyamide paper on either side of Polyester
(PET) film, (Eply NMN) and uncalendared Nomex® aramid paper on either side of Polyester
(PET) film (Eply NMN NC).

Class F 155 C
o
Technical Description
The Eply NMN range of flexible insulation composite materials are produced by laminating various thicknesses of Nomex®
polyamide papers between PET film (Nomex®/PETP film/Nomex®) using a thermally stable adhesive resin as a bonding agent.
The most notable characteristics of Eply NMN materials are:
High tear strength
High inter-laminate shear strength
Thermal endurance to Class F (155 C)
o
High electric strength
Retention of dielectric properties at elevated temperature
Applications
Eply NMN laminates are widely used as slot and slot closure insulation in all types of electric motors and alternators rated up
to Class F temperature rise. The Nomex® polyamide papers provide additional protection against electrical failure at elevated
temperatures. Eply NMN composites have excellent flexibility, tensile strength and tear resistance making them very suitable for
application by automated insertion and forming equipment.
