DOCALENE HD1000 R also contains partially recycled material. DOCALENE HD1000 R has mechanical and economic characteristics between HD 500 and HD 1000.
Polyethylene is one of the most common and widely used family of engineering plastics. In addition to its versatility of use, it is also popular for its low price - it can be just as suitable for certain applications as other, much more expensive materials.
The top grade is ultra-high molecular weight (UHMW) polyethylene, also known as HD1000 (HD = high density), or also referred to as PE HD1000 or simply PE1000, PE 1000 or UHMWPE. Its outstanding abrasion resistance and sliding properties make it a suitable material for wear parts or conductor rails. Other variants are HD8000 with improved properties and Robalon with extra wear resistance.
The next category is high molecular weight (HMW) polyethylene, or HD500, PE500, PE500, PE 500, PE HD500 or HMWPE. HD500 is popular in the food industry and where its outstanding impact resistance or wide range of colours is useful. Sheets are available in blue, red, green, yellow, brown, maroon and grey in addition to the basic white and black colours.
Both the HD1000 and HD500 have a version with partially recycled material. The HD1000 R is available in green and black boards; it has the characteristics to fit between the HD1000 and HD500 and can be an economical substitute for the native HD1000 in certain applications. Only sheets of the regenerate-containing materials are available, while the other material types are also available in rod format.
The lowest category of polyethylene is HDPE (also known as PE-HD, PEHD or HD300), which is an economical material for elements subject to less stress, such as cladding or support elements.
ELS (antistatic, electrically conductive) versions are also available for HD1000 and HDPE.
Polyethylenes are available in a wide range of sizes, typically in stock in sheets 1-120 mm thick and rods in diameters of 10-250 mm.
Some important features
Sliding bearings; sliding guides; cutting tables (food and leather industry); chutes and storage liners for handling granular materials; rollers; small load gears; insulators; shields in the electrical and nuclear industries, etc.
Chipping (turning, milling, drilling, sawing): traditional metalworking tools, in some cases woodworking tools - carbon steel, high-speed steel, carbide, diamond - can be used with a sharp finish. Cooling is recommended to allow high cutting speeds, e.g. v = 100-500 m/min for turning and milling, v = 50-100 m/min for drilling.
Gluing: not recommended.
Welding and shaping: feasible.
