Thermally Conductive Acrylic Interface Pad
5589H
Product Description
3M™ Thermally Conductive Acrylic Interface Pad 5589H is a soft acrylic based pad designed to provide a preferential
heat transfer path away from heat generating components. Because of its softness, 3M Interface Pad 5589H can
decrease the load to integrated circuit chips during compression, and provides good tack to many surfaces. These
properties lead to a high performance non-silicone based thermal pad.
•
Good softness and conformability to non-flat surfaces.
•
Excellent compressive stress relaxation.
•
High thermal conductivity.
•
UL94 V-O certified (File No. E176845).
•
Good surface tack leads to low thermal resistance at surface.
•
Non-silicone acrylic elastomer.
•
Good dielectric performance.
•
Excellent durability for long term thermal conductivity and electric insulation stability.

Shelf Life
3M™ Thermally Conductive Acrylic Interface Pad 5589H shelf life is 12 months from date of manufacture when stored
at room temperature conditions (20-25°C & 50%RH ) and in the products original packaging.
An attribute of the product that can vary with storage is the cosmetic appearance of the material. Slight yellowing may
occur and is considered normal for these type of products. Within the shelf life period, liner release can gradually change
and should be considered to ensure robust end use and processing. Gradual liner release changes that are within the liner
release specification for the shelf life period noted are typical for these products.
