Thermal management materials efficiently dissipate heat for more reliable, compact automotive electronics.
Automotive electrification is one of the hottest trends in the industry, and EV/HV batteries are only the beginning. But the smarter our cars get, the more heat is generated by electronic components. High temperatures can reduce battery lifetime and device reliability, making thermal management essential for optimal long-term performance.
From lithium ion batteries to smart sensors and dashboard displays, 3M thermal management materials are helping manufacturers increase the "cool factor" of automotive electronics. Our thermally conductive, electrically isolating materials can alleviate heat build-up in compact spaces. Our portfolio includes additives for plastic components, specialty glasses, thermal management fluids and a wide variety of interface pads, tapes and adhesives – all designed for efficiency and reliability.
These micro-structured additives improve the thermal conductivity of plastic components without sacrificing electrical insulation. 3M™ Boron Nitride Cooling Fillers are lightweight and easy to process, and they offer a lower cost-in-use than conventional thermally conductive fillers. Plus, they enable thinner, lighter and more compact parts – and greater freedom of design.
Our thermally conductive epoxies and urethanes are ideal for assembly operations that require strong and ultra-thin bond lines. They dispense easily, with excellent surface wet-out and minimal odor. 3M™ Thermally Conductive Adhesives provide a thermal interface between IC packages or PCBs and heat sinks, and can also be used as potting compounds.
Our line of thermal adhesive tapes offers high bonding strength and efficient heat dissipation for heat sink mounting and LED lighting thermal management. Our durable, conformable silicone and acrylic thermal pads improve heat dissipation between the cells, case and heat sink in electric and hybrid vehicle batteries.
Electrically insulating 3M™ Thermally Conductive Adhesive Tapes securely bond heat-generating components to heat sinks and other cooling devices. They offer efficient heat transfer in applications such as Engine Control Units, ABS Systems and Gear Control Units.
For applications such as sensors and battery seals, 3M™ Specialty Glasses offer a number of important advantages. Combining hardness with light weight, these specialty glasses can withstand extremely high temperatures and are highly resistant to corrosion and wear.
Our materials offer efficient thermal dissipation on a heat transfer path between hot spots and cooling devices. With high mechanical strength and long-term stability at high temperatures, 3M™ Heat Spreading Materials are ideal for use with backlights, batteries and printed circuit boards.
3M™ Thermally Conductive Greases offer high thermal conductivity and low thermal resistance, which improves energy transfer from a heat source to a heat sink. Our unique blend of inorganic fillers within a non-silicone matrix provides a thin thermal layer for excellent flow to improve interface wet-out. Available in two viscosities for different application methods.
