Plastic Rod

Petron Thermoplast has been manufacturing and providing semi-finished polymers to industry for over years as a reliable provider of plastic rods. We sell a wide selection of thermoplastics used in various industries and are frequently used in demanding applications as a replacement for conventional materials like metal.

At Petron Thermoplast, we have a huge inventory of machining, display, and speciality grades in various diameters and lengths. Acetal copolymer, which has high stiffness and wears resistance, PVC, strong chemical resistance and outstanding electrical insulating qualities, and polypropylene, which is acid-resistant and lightweight, are popular choices.

Standard engineering grades for general purpose machining, cast moly filled for high load-bearing applications, cast oil-filled for increased wear resistance and lower coefficient of friction are also available.

Alternatively, we provide a variety of polymers such as acrylic, nylon 12, and polycarbonate if great optical clarity is required for display applications. Engineered grades for usage in harsh industrial settings are also available, and polymers like PEEK stand up to strong chemicals, hydrolysis, high temperatures, and wear particularly well.

Explore the website for additional information on different grades of plastic rods, including availability and technical data. If you’re not sure which engineering plastic grade you need for your application, a PDF comparison table and chemical resistance summary may be found at the bottom of this page. Alternatively, you may get in touch with our technical sales team, who would be pleased to help.
