UHMWPE
PE-UHMW is a polyethylene with a very high polymerisation rate. The viscosimetrically established molecular weight (= molar mass) lies between 4 and 10 million g/mol. This extremely high molar mass confines the processing possibilities for this raw material to special extrusion and compression moulding processes.
- extremely high notched impact strength
- high energy absorption capacity at high stress rates
- very good sliding quality
- excellent wear-resistance
- low friction loss values
- very good chemical resistance against acids, bases and aggressive gases
- high resistance against stress cracking
- very good noise reduction
- wide variety of application possibilities due to dimensional stability at
temperatures between -200 and +90°C
The PE-UHMW product range encompasses basic grades, modified grades, and special designs for various applications. The processing material is supplied in powder form and ram extruded into semi-finished products and profiles by way of compression moulding processes.
Its high molecular weight allows PE-UHMW to be applied where lower molecular PE types do not meet the given requirements. Additionally, the property profile of PE-UHMW places this material among the engineering polymers and opens up to it the corresponding areas of application:
Machine Construction
machine components that are subject to high abrasion, such as rollers, cogwheels, chain guides, bearing bushes, chain tensioners
Chemical Industries
rotary pumps, taps, valves, silo coatings
Mining and Coal Processing
linings of conveyor troughs, chutes, trolleys, hoppers
Galvanic Engineering
galvanising drums, bearing shells, cog heels
Electrical Engineering
isolation parts, connector plugs, mountings, cable tongs
Filter Technology, Acoustics
porous moulded parts for filtering liquids, for sound and vibration damping
