PEHD (high density polyethylene) is one of the most used materials ever. It is quite soft, almost “waxy”, therefore it is a little hard to work on it with automatic lathe tools, also because of the long shaving produced during the process.
It is however a cheap plastic material, suitable for various purposes and for contact with food (FDA certified) and not much hygroscopic.
The standard colors you will find in our warehouse are white and black; bars are 2 meters long and diameters from 8 to 300 mm. It is possible to provide larger diameter upon request.
