Announcement of New Gap Filler Materials
Issue Date: 2022/11/14
New gap filling materials

Alpha has expanded its wide range of off-the-shelf products to meet customer requirements.

Alpha offers gap filler materials as a thermal interface option. These materials are soft and compliant, allowing them to fill large gaps between the heat sink and heat source. Gap fillers can also be used when a single heat sink is cooling multiple heat sources.

Alpha has added two additional materials to our standard catalog. Alpha will also offer these gap filler materials in new standard sizes.
