PE-UHMW – the plastic all-rounder for a range of industries.

Material with outstanding wear resistance.

PE-UHMW is characterized by a high molecular weight of 1 million g/mol to 10 million g/mol and exhibits the most balanced property profile of all polyethylenes: this high-performance plastic has very good sliding and wear properties as well as excellent impact strength. PE-UHMW is cold-resistant up to -200 °C as well as offering permanent thermal resistance up to a maximum of +80 °C. Due to its minimal level of moisture absorption, the material also has a particularly high level of dimensional stability and tolerance stability.

In a nutshell: the main properties of PE-UHMW.

• High level of abrasion and wear resistance
• Low coefficient of friction and therefore very good sliding properties
• High impact strength – even at low temperatures
• High resistance to corrosion
• Excellent chemical resistance
• Good electrical insulation
• Excellent dimensional stability
• Self-lubricating effect
• Virtually no moisture absorption
• Excellent dynamic load capacity
• Good noise attenuation
• Physiologically harmless

PE-UHMW by Wefapress for efficient processes.

Whether semi-finished products, profiles and guides or individual plastic parts: as the world's first producer of polyethylene sheets using the press sintering technique, we know exactly what counts in a wide range of applications. Since 1955, all Wefapress PE-UHMW products have been manufactured and processed at our plant in Vreden using high-quality raw materials. By choosing the right material and a specific finishing, we are also able to influence product properties in such a way that they correspond exactly to our customers' requirements: With the help of lubricants, crosslinkers, stabilizers, silicates and more, we modify and supplement the functionality of PE-UHMW (St 1000 as the standard version) for certain applications. What other benefits does Wefapress PE-UHMW have to offer in addition to all the technological parameters? Translucent to milky-white in its basic form, the material can be given virtually any color.

Examples of PE-UHMW modifications.

• St 6000 AST – antistatic
• PharmaStat – antistatic material in color
• St 9100 oil – self-lubricating
• St 6000 MDP – metallically detectable
• St 6000 XDP - visible through X-rays
• CeramX – excellent wear resistance at application temperatures of up to 105 °C
• St 9000 MOS² – withstands high mechanical loads
• St 7000 EHT – for application temperatures up to 100 °C
• St 7000 AMB – with microbial properties
• St 6000 protect – good noise insulation
• St 7000 FRAS - flame retardant and antistatic

PE-UHMW – the perfect fit for every industry.

The performance and reliability of plastics are determined by a wide range of factors. When opting for whichever standard or premium quality, for example, it is important to take (special) properties and areas of application into account. And use in a particular industry is an important criterion too, of course:

• Machine and plant construction
• Port and marine fender construction
• Beverage and filling industry
• Conveyor technology and automation
• Chemical industry
• Agriculture industry
• Bulk materials industry
• Paper industry
• Food processing industry
