HDPE Disc

We offer a range of HDPE (High Density Polyethylene) Discs in a choice of 15 variations. These discs offer the versatility of HDPE which is known for its high strength-to-density ratio and chemical resistance. These 2 properties see it commonly used in plastic bottles, corrosion-resistant piping and plastic lumber. HDPE discs can serve as prototypes or samples to test machining and fabrication processes. Engineers may also use them to explore HDPE's suitability for mechanical parts or chemical equipment components. With an array of sizes and thicknesses to choose from, Goodfellow's HDPE Discs can meet the needs of both research and industrial applications.
