  • Plastics That Conduct Heat | Plastics Technology

    ApplicationsMembersCriticismsAdvantagesTechnologyCostConstructionFutureResearchProductsScopeHeat sinks and other heat-removal applications are among the last areas where thermoplasticsinherent thermal insulatorshave yet to replace metals. Until fairly recently, that is. Modifying plastics to improve their thermal conductivity is a burgeoning area of opportunity for a handful of compounders. They have taken up the challenge of using plastics to solve problems of heat build-up in electronics, appliances, lighting, automotive, and industrial products. Thermally conductive compounds are generally not considered to be direct drop-in replacements for metals. Instead, they open up a broad range of new opportunities for thermal management applications. Parts molded out of this new generation of materials can replace metals and ceramics in some applications, and non-conductive plastics in others. Uses include custom-molded heat sinks on circuit boards, as well as tubing for heat exchangers in appliances, lighting, telecommunication devices, business machines, and industrial equipment used in corrosive environments. Heat sinks often involve plastic overmolded on a metal heat pipe. Lighting applications also include reflectors, laser-diode encapsulation, and fluorescent ballasts. Automotive headlamp reflectors are in development. In temperature sensors like thermistors, thermally conductive plastic encapsulation can help improve the response of the temperature sensor itself. Thermally conductive compounds are also used to encapsulate small motors and motor bobbins. A diesel fuel pump uses a thermally conductive plastic to help keep fuel flowing in sub-freezing temperatures. His company has demonstrated the concept in certain applications where thermally conductive plastics provide heat transfer equivalent to aluminum and copper designs. Adds Mark Kaptur, LNP product marketing manager, Where conductivity is the limiting factor, metal is the preferred material. But there are many applications where convection is the limiting factor, and then thermally conductive plastics are a better fit. Among the most commonly used heat-conductive additives are graphite carbon fibers and ceramics such as aluminum nitride and boron nitride. Graphite fibers conduct electricity as well as heat, which suits them to applications where RFI shielding is required, such as hand-held communication devices. By contrast, the ceramic additives are electrically insulative. They are suited to applications that come into contact with electrical leads. Virtually all the suppliers of thermally conductive compounds offer both electrically conductive and insulative types. Thermally conductive compounds are usually formulated with crystalline engineering resins due to their high heat resistance and lower melt viscosities, but amorphous resins can also be used. Cool Polymers, for instance, has developed a thermally conductive polysulfone compound. In general, conductive compounds have higher stiffness and strength, but lower impact properties than unfilled or glass-reinforced resins. For example, a glass-reinforced nylon 66 has a notched Izod impact of around 1.7-1.8 ft-lb/in., while a thermally conductive, electrically insulative nylon 66 has a notched Izod of 1.0 ft-lb/in. Says Cool Polymers Miller, In the mid-temperature engineering resins group, we have aimed at applications for heat sinks in smaller stepper-motors for a broad range of industrial equipment. In the commodity resins area, we see potential for PP-based compounds and possibly PS in non-electronic applications such as food-related consumer heating and cooling products. See full list on ptonline.com Among the pioneers, whose heat-conductive compounds have gone commercial in just the last couple of years, are PolyOne Corp., Cool Polymers, LNP Engineering Plastics, RTP Co., and Ticona Corp. GE Plastics, DuPont, and A. Schulman have development programs under way. And last month, PolyOne entered into a joint-development agreement with Cool Polymers in order to utilize the latters capabilities in tool design, thermal-management testing, and injection molding of prototype applications. See full list on ptonline.com However, it can be argued that metals high thermal conductivity cannot be effectively utilized if they conduct heat to the surface of a product faster than air-flow convection can remove heat from the surface. According to Jim Miller, product manager at Cool Polymers, Heat transfer in many applications is convection-limited (that is, design-dependent), not conduction-limited (material-dependent). See full list on ptonline.com Also, thermally conductive plastics typically boast lower coefficients of thermal expansion (CTE) than aluminum and can thereby reduce stresses due to differential expansion, since the plastics more closely match the CTE of silicon or ceramics that they contact. Conductive plastics also weigh 40% less than aluminum; they offer design freedom for molded-in functionality and parts consolidation; and they can eliminate costly post-machining operations. See full list on ptonline.com Many technological advances utilizing microelectronics would have been impossible without thermally conductive plastics, according to Miller of Cool Polymers. This ability to control heat build-up, yet also provide lightweight, flexible, and low-cost applications will make these plastics one of the most important technological developments for decades to come. See full list on ptonline.com High initial cost is currently the biggest obstacle to wider acceptance of thermally conductive compounds. A key factor is the high-priced fillers used to achieve good heat conduction, which result in these compounds costing at the very least two and a half times as much as metal or ceramic materials they might replace. Many thermally conductive compounds sell in the $25-$45/lb range, though some with lower conductivity cost as little as $4 to $6/lb. Suppliers say the technology is currently best suited to high-volume production (e.g., 10,000 parts/month) in order to realize the design and fabrication advantages of injection molding. Cool Polymers Miller says cost savings of up to 30% have been achieved in replacing a metal design. However, he notes that part size can make a critical difference. For a small part, the majority of the cost is in the injection molding process, while for larger parts, material is the big factor. Because of their higher upfront costs, thermally conductive plastics have an advantage for smaller unitsup to 1-lb. See full list on ptonline.com The most thermally conductive additives are specialty graphite fibers made from petroleum pitch. They have conductivity values of 500-1000 W/mK. By comparison, structural-grade carbon fibers based on polyacrylonitrile (PAN) have conductivities less than 10 W/mK. Thermal conductivity of electrically insulative ceramic fillers are 60-80 W/mK for boron nitride and 300 W/mK for aluminum nitride powders. According to Sam Johnson, industry manager for BPs Carbon Fiber Industrial Composites, most commercial uses of pitch graphite fibers require conductivity in the range of 500 W/mK. This typically requires high fiber loadings (up to 70%). Even at such high loadings, Johnson says fairly long flow paths are possible with crystalline plastics like LCP and PPS, owing to their excellent interfacial compatibility with graphite fibers. Johnson adds, You dont need to cool the mold because these fibers are very thermally conductive. As a result, the compounds cycle quickly. See full list on ptonline.com BP is currently the sole North American maker of pitch-based graphite fibers. Conoco aims to become a second source when it starts up production of specialty pitch fibers at a new plant in Ponca City, Okla., early next year. Although BPs ThermalGraph pitch-based fibers sell for around $25/lb, BP has developed a low-cost process that will reduce prices by at least 25%, Johnson says. BP expects to begin using the new process early next year. See full list on ptonline.com Initial work on heat-conducting thermoplastics has focused on highly heat-resistant resins like LCP, PPS, PEEK, and polysulfone. PolyOne is also testing new compounds based on polyetherimide (GEs Ultem). Suppliers are now expanding their range to include medium-temperature resins like ABS, PBT, polycarbonate, and nylon, as well as lower-temperature commodity plastics like PP and PS. Even TP elastomers are getting the thermal-conductivity treatment. See full list on ptonline.com Cool Polymers CoolPoly line today includes compounds of LCP, nylon 66, PC/ABS, and PPS. They offer thermal conductivities up to 60 W/mK, depending on resin type. Elastomeric TPO compounds are in development. The company offers to custom formulate thermally conductive grades of any engineering or commodity thermoplastic. LNPs Konduit line includes PPS, PP, and nylon 6 and 66 grades. These resins are compounded with carbon, ceramic, or metallic fillers and small amounts of glass reinforcements, if needed. A lower-cost product group uses ceramic or metal additives to provide thermal conductivity up to 2 W/mK. A high-performance product group uses a specialty carbon fiber to achieve 10 W/mK. LNP can offer customized Konduit products in any crystalline thermoplastic. See full list on ptonline.com PolyOnes Therma-Tech line includes compounds of LCP, PPS, and PPA (BPs Amodel) with thermal conductivities up to 10-12 W/mK. Newer additions include a TPV (flexible crosslinked TPO). See full list on ptonline.com
