Our Expertise

For over a decade ESG have been supporting the continued evolution of the electric revolution. We work closely with many of the biggest names in the EV sector, from small scale R&D projects to working directly with electric vehicle OEMs.

We produce insulators and thermal interface components for use within EV powertrain, power electronics and battery systems.

As a company we have intricate knowledge of the challenges faced within E machine development, both radial and axial flux. We have an in-depth knowledge of the thermal management requirements of modern-day power electronics and associated systems.

Our specialities which have been developed over the last decade include:

Evans Shims & Gaskets - NKN Slot Liners

Precise manufacturing and forming of slot liners, considering retention, either mechanically or by use of specialist adhesives, the implications of potting procedures and stator build.

Evans Shims & Gaskets - Polyimide Slot Liners

Expertise in the challenges encountered in electrical isolation, from the use of specialist polyimides, with and without silicone and acrylic adhesives, and with an understanding of their modes of application. To intricate heat forming of Formex™ for use as isolation modules.

Evans Shims & Gaskets - Gap Pad

Experience in the thermal challenges faced in modern power electronics, we utilise a huge range of Gap Pad products from manufacturers such as Bergquist® and Denka®. Our precision conversion of these materials is coupled with our knowledge of specific material thermal conductivity and insulation properties.

Evans Shims & Gaskets - Selective adhesive

Skilled in the manufacture of components with specialist adhesives applied to a selective area, these parts can also be intricately creased and formed. We manufacture various tooth liners that have adhesives selectively applied to aid in application. Adhesives range in thickness from as thin as 50 microns and are specifically selected for their thermal and mechanical properties

Evans Shims & Gaskets - NKN Slot Liner

Our stock is geared to the EV and power electronics sectors; we have one of the most detailed ranges of polyimides in Europe, including Dupont™ Kapton® grades ranging from HN through to the most modern MT+ grades. We also stock various grades of laminate materials, including Nomex Mylar Nomex® and Nomex Kapton Nomex®. We stock a large range of hard to find grades and have a worldwide supplier base to assist.

Evans Shims & Gaskets - NKN Stator

Unparalleled knowledge and experience working with specialist materials including PTFE, PEEK, polyimides, thermoplastics and much more.

As of 2021, the three fastest electric hyper cars in the world contain our insulation components.

We are involved in the constant development of Formula E powertrains.

Our precision forming of slot liners is utilised by some of the largest EV OEMs within the UK and Europe.
