Multi-ply Laminates

The combination of insulation sheets and films into a multi-ply laminate product is common within the electrical industry.

There are a wide variety of such laminates available, all offering excellent insulation & mechanical properties to suit a wide range of applications.

Typical products are:

Aramid/Polyester/Aramid – this is a 3-ply laminate consisting of aramid insulation paper, polyester film and a further layer of aramid insulation paper.  A common brand name for this type of material is NMN ® or Nomex/Mylar/Nomex ®.   This product offers high dielectric breakdown, excellent tensile strength and very good initial tear strength.

This kind of construction is also available as Aramid/Polyimide/Aramid perhaps best known as Nomex/Kapton/Nomex ® for greater dielectric performance.

These products are laminated using a high temperature adhesive system.  They are designed not to delaminate or blister in high stress environments and will offer excellent long term thermal & mechanical stability.

Depending on the application these laminate products can also be offered in a 2-ply version. 

DMD – this product is a 3-ply laminate consisting of non-woven polyester tissue, polyester film and a further layer of non-woven polyester tissue.  A common brand name for this material is Dacron/Mylar/Dacron ®.  The product offers excellent dielectric breakdown qualities and good mechanical strength and resistance to high temperatures.  

Elephantide/Polyester

Elephantide/Polyfilm composites are flexible sheet materials with high mechanical strength produced by bonding polyester film to elephantide electrical paper using synthetic adhesive.  The polyester film enhances the electrical characteristics of the elephantide paper which offers good electrical and thermal insulation properties as well as mechanical durability.  A common brand name for this kind of laminate product is Ele/Meli ® 

These laminate products offer tough, durable & flexible insulation solutions to a wide range of electrical and electro-mechanical applications across the electrical, industrial, transport, aerospace and automotive industries as well as many others.
