Obviously, it is a trend that thermally conductive adhesives will be applied in electric vehicle battery pack instead of encapsulant.

What kind of material is thermally conductive adhesive? GLPOLY thermally conductive adhesive XK-D20 is two-component, epoxy based, dispensable adhesive with a thermal conductivity of 2.0W/mK.

XK-D20 thermally conductive adhesive (thermal gap filler) has a high bond strength with room temperature cure. The strong bonding eliminates the need for mechanical fasteners and maintains structual bond of 8MPa in severe environments.

It is supplied in two-component format, mix ratio 1:1 by volume and suitable for automated dispensing equipments, improving productivity and saving cost.

Bergquist Liqui-Bond EA1085 is the most famous one, let’s check it out what material it contains and how about the thermal performance is.

Bergquist Liqui-Bond EA1085 is a epoxy based, dispensable adhesive, it has a thermal conductivity of 1.8W/mK, it provides a lower performance than GLPOLY XK-D20 thermally conductive adhesive. Absolutely, GLPOLY XK-D20 can substitute for Bergquist Liqui-Bond EA1805.

GLPOLY XK-D20 thermally conductive adhesive will deflect easily under very low compressive forces resulting  in thin bondliness and very low stress applied on fragile components. It is recommended for filling irregular surface.

XK-D20 thermally conductive adhesive provides high thermal performance, strong bonding and vibration dampening, it is ideal for thermal management of electrical vehicle battery pack.

GLPOLY has cooperated with A123 system, NIO Auto, Han's Laser, LG etc, providing complete portfolio of thermal interface materials for customers to protect their brand reputation for performance and reliability.
