Torlon, is the highest performing, melt processable plastic. It is a polyamide-imide that is available in different shapes that are provided in injection molded, compression molded and extruded grades. The different stock shapes, such as Torlon rod, offer engineers and equipment designers, greater compressive strength, as well as better impact resistance when compared to many other high performance engineering plastics.
There is more than one type of Torlon rod that is available to those who require this particular high quality, versatile thermoplastic material. For instance, there is:
4230 – This grade is often utilized for insulators and electrical connectors because it has high dielectric strength. Having dielectric characteristics means that the material is an electrical insulator and it can be used to effectively insulate wire and cable, protecting connections from corrosion and moisture.
4301 – Commonly used for friction and wear parts, this Torlon rod has characteristics that include low coefficient of friction and exceptionally low expansion rate, as well as shows little or no signs of slip-stick when in use. This grade does particularly well in extreme service wear applications, such as reciprocating compressor parts, seals, bearings and bearing cages that are non-lubricated.
5030 – This is extruded PAI (polyamide-imide) that is 30 percent glass reinforced. It is perfect for electronic or higher load structural applications. It is typically chosen over other grades when the greatest degree of dimensional control is needed or when smaller shapes are required.
Therefore, the grade of Torlon rod that is utilized often depends on what is best suited to the application to ensure top performance and efficiency.
