Technical Data May 2012 3M Thermally Conductive Acrylic Interface Pads 5589H and 5590H Product Description 3M Thermally Conductive Acrylic Interface Pads 5589H and 5590H are soft and acrylic based pads. Because of their softness, Interface Pads 5589H and 5590H can decrease the load to integrated circuit chips during compression, and have good tack to many surfaces. These properties lead to a high performance non-silicone based thermal pad. Interface Pad 5590H is a higher thermal conductivity and somewhat firmer acrylic thermal pad, versus Interface Pad 5589H. 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 Pads 5589H and 5590H shelf life is 12 months from date of manufacture when stored at room temperature conditions (20-25C & 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. (2)
