-86.73%HDPE (high-density polyethylene) is a light, tough, slippery plastic. It weighs 0.94–0.97 g/cm³, barely absorbs water, resists acids, bases and many solvents, and takes impacts without breaking. That is why it is used for wear pads and guides, slide strips, plates, guards and parts for food and chemical equipment. At PREMSA we CNC mill and turn it from your file, starting at a single part with an instant price.
HDPE (high-density polyethylene) properties: mechanical, physical, thermal and chemical data to choose the material for your machined part.
Material Type
Semi-crystalline thermoplastic (polyethylene)

What people ask most about HDPE parts: what it is, uses, machining, friction, strength, temperature, chemicals, food contact, outdoor use, bonding, price and tolerances.
HDPE is chosen for parts that have to slide, take impacts and resist chemicals and water: slide pads, wear guides, slide strips, plates and guards.
At PREMSA Industries we machine HDPE with CNC milling and turning from your file, from a prototype to production.
HDPE is chosen when the part has to slide, take impacts and not be affected by chemicals or water.
If your drawing doesn’t specify tolerances, we machine to ISO 2768-m (medium). On dimensions you call out —slots, holes and fits— we can hold ±0.1 mm (±0.004 in), and critical dimensions are checked in inspection. HDPE is soft and expands with heat, so tight dimensions are measured at room temperature.
HDPE is machined with CNC milling, CNC turning, drilling and tapping. It cuts easily but is soft: it is clamped without over-tightening so it doesn’t distort, cut with sharp tooling so it doesn’t leave burrs and with air or coolant so it doesn’t heat up. A thread tapped straight into HDPE is weak; if it will be tightened often, an insert is added.
Because it slides, takes impacts and resists chemicals, HDPE is used in many parts made with CNC machining.
HDPE is usually the right choice when the part has to slide or take impacts in contact with water or chemicals, without high loads or heat.
