strength: 20–24 MPa (yield stress),
high toughness (notched Charpy): does not break,
good sliding capabilities: m = 0,2–0,3 (dry sliding on smoothed and ground steel),
machinable, weather resistant,
wide temperature range for application: from - 80°C to +110°C,
hardness (Shore): D 60 – D 65,
good damping capability,
does not expand in the presence of moisture, good resistance to chemicals,
physiologically neutral, it can come in contact with food and medicine,
HD 1000 material: good abrasion wear resistance in comparison with the PA, POM and the PETP materials,
density: 0,96 kg/dm3
Cutting (turning, milling, drilling, sawing):Traditional metalworking – or in certain cases, woodworking tools – carbon steel, rapid steel, hard metal, diamond can be used in sharp design only. Cooling is recommended, which allows high cutting rates e. g. v = 100–500 m/min for turning and milling, v = 50–100 m/min for drilling.
Adhesive bonding: not suggested.
Welding and forming: feasible.
DOCALENE (UHMW polyethylene) Products
In comparison with HD 500 it is extremely hardy even under –200°C and its abrasion wear resistance is better.
DOCALENE HD1000 ELS
It has the best abrasion wear resistance and toughness. Electrically conductive material, protected against UV radiation. Surface resistance is 103 - 105 Ω.
All these properties make it extremely popular in all areas from the electronic industry to material handling.
DOCALENE HD1000 R
It contains partially recycled materials. The mechanical and economic characteristics are between those of HD 500 and HD 1000.
Due to moderate mechanical characteristics, it is used in locations subjected to lesser stress, it is highly economical.
DOCALENE HD300 ELS
It has improved heat resistance. Electrically conductive PE version. Surface resistance is 103 - 105 Ω. Often used in ectronics and microelectronics for housing and cover parts.
It offers an ideal combination from the aspect of rigidity, toughness, mechanical damping and abrasion wear resistance. It is readily weldable, as well. Besides the applications in food industry (certified), it is used in mechanical, chemical and electric industry, as well.
Especially produced for implant application in medical activity.
