Working with HDPE ESD

Is HDPE easy to machine?

Cuts easily with sharp, high-rake, polished tools and high speed/low feed; use air blast and generous support since heat build-up and low modulus cause gumming, burrs and part distortion.

Can HDPE be welded?

Excellent hot-plate, butt-fusion, electrofusion, hot-gas and extrusion welding (DVS 2207); adhesive bonding requires corona, flame or plasma pre-treatment.

Can HDPE be formed, bent or molded?

Injection, blow, rotational and profile extrusion all standard; melt 200–260 °C, mould 20–60 °C, allow 1.5–3% shrinkage with strong anisotropy and post-mould shrink over 24 h.

What surface finishes work on HDPE?

Cannot be plated or anodized and holds paint poorly; use in-resin colour, laser marking, hot stamping or corona-treated printing, and flame-polish or scrape edges for smooth finishes.

HDPE ESD — frequently asked

What is HDPE ESD used for?

HDPE ESD is typically used for cutting boards and food-contact surfaces, PE100 pressure pipe and fittings, chemical and water storage tanks, blow-moulded bottles and jerricans, playground equipment panels and conveyor wear strips and guides. In short: chemical resistant; budget.

What is the yield strength of HDPE ESD?

HDPE ESD has a typical yield strength of 22 MPa (3.19 ksi) and a tensile strength of 24 MPa (3.48 ksi) — weaker than 78% of polymer grades. Strength varies by condition: see the 12 listed tempers.

Is HDPE ESD easy to machine?

Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Cuts easily with sharp, high-rake, polished tools and high speed/low feed; use air blast and generous support since heat build-up and low modulus cause gumming, burrs and part distortion.

Can HDPE ESD be welded?

Yes — weldability is rated very good (80/100). Excellent hot-plate, butt-fusion, electrofusion, hot-gas and extrusion welding (DVS 2207); adhesive bonding requires corona, flame or plasma pre-treatment.

What surface finishes work on HDPE ESD?

Cannot be plated or anodized and holds paint poorly; use in-resin colour, laser marking, hot stamping or corona-treated printing, and flame-polish or scrape edges for smooth finishes.

Can HDPE ESD be formed, bent or molded?

Injection, blow, rotational and profile extrusion all standard; melt 200–260 °C, mould 20–60 °C, allow 1.5–3% shrinkage with strong anisotropy and post-mould shrink over 24 h.

What is the maximum service temperature of HDPE ESD?

HDPE ESD is rated for continuous use to about 80°C (176 °F), and briefly to 110°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
