Welding Rod in PE-HD black

PE-HD, polyethylene in a hard grade, is one of the most used standard plastics in industry. The material is light, tough and easy to machine with saw, mill and lathe. It is good value for parts that have to take moisture, chemicals and impact without needing the wear strength of ultra high molecular weight polyethylene.

The density is 0.95 g/cm³ and the water absorption is 0.01 percent, so parts do not change dimension from moisture. The yield strength is 27 MPa, the tensile modulus 1047 MPa and Shore D 67. The melting point is 131 °C, the continuous maximum service temperature 80 °C and the short term one 120 °C. The material takes temperatures down to -63 °C without turning brittle.

PE-HD takes water, salt, most acids and bases as well as water borne chemicals. It has good electrical insulation with a dielectric constant of 2.3 at 1 MHz and a dielectric strength of 45 kV/mm. The fire rating is UL 94 HB. Food approval is in place per EU 10/2011 and FDA.

Typical uses are tanks, vats, tubes, cutting boards, spacers, slide rings and sleeves in water and chemical environments. PE-HD is welded with hot air or a welding rod and can be bonded with suitable polyethylene adhesives.

PE-HD is used for tanks, vats, tubes, cutting boards, spacers, slide rings and sleeves in water and chemical environments. The material can be sawn, drilled, milled and turned with ordinary tools for plastic. Welding is done with hot air or a welding rod, and bonding is possible with suitable polyethylene adhesives.

You get the welding rod in PE-HD in black, suitable for tight joints in sheets, tubes and parts.
