Comparison between HDPE and UHMWPE
HDPE VS UHMWPE |
|
HDPE is high density polyethylene |
UHMWPE is ultra-high molecular weight polyethylene |
Structure |
|
HDPE has short polymer chains compared to UHMWPE |
UHMWPE has very long polymer chains |
Molecular weight of polymer chains |
|
The polymer chains of HDPE has low molecular weight than UHMWPE |
UHMWPE polymer chains have very high molecular weight |
Molecular weight of raw materials |
|
HDPE with less than 500,000 g/mol |
UHMWPE above 2000,000 g/mol; according to standard QB/T 2668.1-2017 Ultra-high-molecular weight polyethylene (PE-UHMW) pipes |
Fabrication |
|
HDPE can be shaped and welded using thermoplastic equipment (HDPE straight pipe is thermal welded onto HDPE stub) |
UHMWPE can be fabricated and machined, while not suited to forming specific shapes and welding. (UHMWPE straight pipe get stub from the pipe itself through infrared heating) |
Pipe Production speed |
|
HDPE pipe: Approximately 8000~10000kgs/extrusion machine/day. Vary from pipe size and extrusion machine capacity |
UHMWPE pipe: Approximately 200~300kgs/extrusion machine/day. Vary from pipe size and extrusion machine capacity. |
Application |
|
HDPE application |
UHMWPE application |
3D printing, can be shaped into any type of product that may need a sturdy and dense foundation |
Machined into components like wear strips, chain guides, bumpers, bearings, guide rails, construction surface, outrigger pads. |
water pipeline, sand dredging pipeline, mineral slurry transport liner. |
Marine pile sleeve, dock fenders |
|
High wear and corrosion resistance application at mineral slurry transport, sea water dredging, brine saline water transport, chemical pipeline at power plant. |
