Round Rod in PET FG 1219.2 mm natural

Round rod in PET FG is the food approved version of the PET rod, certified to EU 10/2011 and FDA for direct contact with food. The material is the same at its core: crystalline polyester with a dense molecular structure, but the recipe is reviewed to stay inside the migration limits and the pigments are free from problem substances. That is the difference from ordinary PET, and the reason the rod is a standard choice for turned parts in filling and packaging lines.

Density is 1.39 g/cm³. The material handles continuous operation up to 115 degrees and the lowest service temperature is around -20 degrees, so the rod holds through the whole span from cold room to hot filling. Tensile strength is high, the surface hard and smooth, and wear resistance even over time. Water absorption is 0.5 percent, which is low compared with nylon and means turned parts keep their dimensions through washing and cleaning. That is often the deciding point in a line where every millimeter of play builds up into a stopped conveyor. The fire rating is HB.

Typical parts you turn from PET FG rod are plain bearings, shaft bushings, sprocket centers, spacers, small guide rollers, dosing pistons, vacuum cup holders and mold parts in cap feeders. In the food and packaging industry, PET FG often replaces PA6 or POM C precisely because the rod does not draw moisture and is not broken down by cleaning chemicals in the same way. Against steel shafts the material runs clean without lubrication, which is a concrete operating advantage when oil has no place in the process.

In turning, PET FG gives beautiful continuous chips and good surface finish. Use a sharp tool and keep the coolant running, and you avoid the heat buildup that can otherwise leave stresses in the material. Drilling and tapping work easily, but pre drill in several steps for large holes so the rod does not grab. Press fitting works thanks to the high stiffness, as long as you dimension for the moderate thermal expansion.

The rod is supplied in a wide span of diameters, from small turning blanks to heavy blanks. The natural color is milky white to cream. When you stand between PET FG, POM C FG and PA6, PET FG is often the choice when you need low water absorption plus stiffness and a hard surface. POM C FG can be better for pure plain bearings but weaker on UV and weldability, PA6 has higher impact strength but moves considerably with moisture.

The rod at 1219.2 mm in natural color is turned into bushings and gears that meet the food, approved for direct contact with food.
