High temperature resistant plastics are increasingly being used in motor and gear parts – hot fuel systems and air manifolds of automobiles, industrial machinery products, and aviation and marine engine segments – environments that would have degraded previous generation polymers. While some of these materials are newly produced plastics such as sulfone polymer, others are the latest additions to polymer series developed decades ago.
“One of the toughest applications for plastics in automotive motors is in bearings, which have to be developed to withstand high temperatures, pressures, wear, and chemical aggression, but at lower cost,” explains Frost & Sullivan Research Analyst Michael Valenti. “For this, companies need to employ a strong chemical engineering presence in their research and development divisions.”

In Japan, Mitsui Chemicals Inc. manufactures AURUM, a recyclable thermoplastic polyamide resin that can be injection molded to make an array of parts that include bearings and retainers, burn-in-sockets, [...]ings, gears, seal rings, thrust washers and disks, valves, the trays and carriers used in semiconductors, hard disc manufacturing, and thermal and electric insulators.
Potential end users need to be convinced of the efficacy of these plastics to withstand high temperatures, as well as their chemical and hydrolytic strength, since doubts linger regarding their performance.
However, high manufacturing expenses force producers to increase the cost of the plastics. This proves to be the greatest restraint for the increased use of these materials.
Opening of new markets is the fastest way to increase demand. Leading plastics makers already involved in high temperature product development expect to continue in it, particularly for applications such as automotive and marine engines where there is money available to buy more expensive products.
In the U.S., companies such as DuPont Inc, Solvay Advanced Polymers, Performance Plastics Ltd and many others continue to formulate newer versions polymers whose high thermal resistance will find them uses in automotive and industrial fuel systems.
Plastics processing continues to be more sensitive to environmental factors such as humidity, than metalworking. However, this is cancelled out by what the products offer in other ways.
“Injection molding high temperature resistant plastics provide part makers with design flexibility, high production rates, lower labor costs, and less or no finishing of molded parts,” says Valenti. “This compared to the costly and labor intensive forging, casting, cutting and grinding of metals are all reasons for the move towards polymers.”
Compared to metals, plastics are light weight. This translates into greater fuel efficiency, a gain brought home by the ongoing spike in gasoline prices. As alternatives to the internal combustion engine get closer to commercial adoption, there will be a continued adoption of light weight materials in place of metals.
Through computer-aided-design (CAD) tools, polymers can now be custom-designed to meet specifications, such as elevated temperatures and humidity, in distinct applications. Design engineers are also utilizing CAD to predict how a plastic gear will perform with greater accuracy, thus improving their development and demand.
Paricipants can also take advantage of the fact that plastic gears are corrosion resistant, and reduce noise significantly. This in addition to their low maintenance costs and longer wear can open up tremendous oppurtunities in the market.
