Round Rod in PET 1000 mm white

Round rod in PET is made for the lathe. The material is a crystalline polyester thermoplastic that barely moves when you take the chip off, which means finished parts hold their dimensions and do not straighten out on the bench the next morning. That is the difference from softer engineering plastics when you work to tight tolerances.

The density is 1.39 g/cm³ and the material takes continuous operation up to 115 degrees. The lowest operating temperature is about -20 degrees, which makes the rod usable in most indoor and process environments. The tensile strength is high, the surface hard wearing and the creep low under load. The water absorption is 0.5 percent, so the rod barely moves with the moisture, a concrete advantage over nylon when you turn precision parts. PET is fire rated HB.

Common turning jobs in PET are plain bearings, sleeves, spacers, gears, cams, guide wheels, small rollers and shaft ends in conveyors and filling machines. In the food and packaging industry the material is often the first choice when you need low water absorption plus a hard, smooth surface that stands up to cleaning. PET works well against steel and other plastics without extra lubrication, which makes it a concrete alternative to POM when you need a little more stiffness and a little more heat resistance.

In turning PET gives beautiful, continuous chips and clean surfaces. Use sharp tools, moderate depths of cut and generous cooling and you keep the heat down and the tolerances within reasonable limits. The material drills and taps easily, but remember to pre drill in several steps for large holes so the rod does not grab. Press fitting works well thanks to the high stiffness, as long as you size for the moderate thermal expansion.

The rod is supplied in a wide range of diameters, from small turning blanks to heavy blanks for larger parts. The natural color is milky white to cream. When you are choosing between PET, POM C and PA6, PET is often the pick when you want stiffness and dimensional stability in a normal workshop environment, without the moisture problems of PA and without the poorer bondability of POM. If you are looking for food approved material, PET FG is the same base material but certified to EU 10/2011 and FDA.
