When engineers need materials for critical applications, they turn to high-performance engineering plastics. Products like PEEK, Torlon®, Rulon®, Vespel®, and Ultem® can add great durability to different projects. As you consider these products for your next project, you may wonder about their differences. This blog can help you identify the material best suited to your objective as we compare high-performance engineering plastics.
PEEK
PEEK, otherwise known as polyetheretherketone, performs well in environments with high pressures, temperatures, or corrosive chemicals. Engineers in the aerospace and medical device sectors have found this thermoplastic to be especially effective under stress.
Additionally, when subjected to temperatures as high as 480 degrees Fahrenheit, PEEK remains dimensionally stable and maintains its structural integrity. It also resists damage from harsh chemicals, including acids, bases, and hydrocarbons, making it suitable for chemically aggressive environments. PEEK also features a low friction coefficient, enabling its use in bearings and gears.
Torlon®
Another high-performance engineering plastic that shows resistance at elevated temperatures is Torlon®, also known as polyamide-imide. Aerospace and electrical engineers employ Torlon® because it remains mechanically stable at 525 degrees Fahrenheit. Its insulation properties make it a strong candidate for use in electrical components. Torlon®’s resistance to wear also contributes to its use in products that require extreme durability, such as high-performance bushings.
Rulon®
Engineers seeking a plastic with self-lubricating characteristics should consider Rulon®. This plastic can minimize wear during long-term operations. Rulon® material also offers a low coefficient of friction and chemical resistance. This fusion of different qualities has allowed engineers to use it in applications such as sliding parts, pistons, and rotary seals. Additionally, the material is reliable under varying loads and speeds since it requires no external lubrication.
Vespel®
If you are looking for a material that offers versatility in high- and low-temperatures, consider using Vespel®. This plastic can withstand cryogenic temperatures, as well as highs of 572 degrees Fahrenheit. Vespel® is useful in aerospace, automotive, and industrial applications.
Its resistance to creep ensures longevity in components subjected to continuous heat and pressure, such as in jet engines or automotive transmissions. Electrical engineers also value Vespel® for its dielectric properties, as it delivers high insulation while maintaining thermal stability.
Ultem®
Another high-performance engineering plastic to consider is Ultem®. This polyetherimide boasts an excellent strength-to-weight ratio, and manufacturers utilize it in the medical, electronic, and aerospace industries.
Ultem® also possesses a high dielectric strength, supporting applications that require electrical insulation. It offers flame resistance, making it a great choice in applications that require compliance with safety regulations related to flammability.
