High-Density Polyethylene (HD-PE) or PE 300 Rods
Our High-Density Polyethylene rods, also known as HDPE or PE300 rods, exhibit exceptional impact strength, even in extreme temperatures as low as -30ºC. With a low coefficient of friction and ease of fabrication, these rods are highly versatile and find widespread application in various sectors, including automotive, leisure, and industrial industries. They are especially well-suited for crafting tanks, silos, hoppers, and more.
These rods go by several names, including HDPE rods, PE300 rods, and PE300 grade polyethylene. They offer ease of welding and machining, making them a preferred choice for many applications. It’s important to note that the maximum working temperature for High-Density Polyethylene rods is +90ºC.
