Thermal Glue Strips & Polyamide Solutions | 15+ Years Expertise

Thermal glue strips represent a specialized category of adhesive-based solutions for thermal management, where a high-performance, thermally resistant adhesive is formulated onto a carrier substrate to create a bond that also provides thermal insulation. Unlike mechanical thermal breaks, these strips focus on applications requiring a seamless, bonded interface to mitigate heat transfer across joints and gaps in electronics, automotive assemblies, and certain building components. The key to their functionality lies in the adhesive chemistry, often based on silicone, acrylic, or epoxy systems, which are loaded with thermally insulating fillers like ceramic microspheres, glass bubbles, or mineral oxides to achieve low thermal conductivity, typically in the range of 0.1 to 0.5 W/m·K. The carrier, which could be a plastic film, glass cloth, or non-woven material, provides dimensional stability and handling strength. These strips must maintain their adhesive properties and dimensional integrity across a wide service temperature range, often from -40°C to over 150°C, without degrading, outgassing, or losing adhesion. They are engineered for specific surface energies to ensure proper wetting and bonding to various substrates like metals, plastics, and composites. In addition to thermal insulation, they may provide other functions such as vibration damping, electrical isolation, or environmental sealing against moisture and gases. Selection criteria involve peel strength, shear resistance, thermal impedance, and compliance with industry standards for flammability (e.g., UL 94) and outgassing (e.g., NASA low outgassing). Their use simplifies assembly processes by eliminating the need for mechanical fasteners in sensitive applications, making them a critical component in the design of compact, efficient, and reliable systems where thermal bridging must be minimized without compromising structural integrity.
