GUR® UHMW-PE Specialty Products

A full range of GUR ultra-high molecular weight polyethylene (UHMW-PE) and very-high molecular weight polyethylene (VHMW-PE) specialty products, in powder forms and tailored for specific functional properties, launches UHMW-PE into another realm of potential applications. With Ticona’s advanced polymerization and powder manipulation technology, GUR Specialty Products provide:

• Specialized particle morphology and low bulk density
• Various particle size distributions, including micropowders
• Engineered processibility and performance
• Consistent quality

Typical applications for GUR Specialty Products include polymers to fabricate porous and filtration parts and also additives for paints, coatings or material matrix modifiers.

Some typical processing and performance benefits that GUR Specialty Products provide for porous and filtration applications are:

• Well controlled porosity and flow resistance
• Improved damping behavior
• Excellent uniformity of raw material
• High consistency of powder properties and quality
• Good compatibility with other filter media such as activated carbon
• Good mechanical strength
• Outstanding chemical resistance
• FDA, USDA and NSF compliant grades

During the free-sintering process, the surfaces of individual polymer particles fuse at their contact points forming porous structures that have found use in applications such as:

• Absorbent wicks
• Aerators
• Analytical and diagnostic supports and reservoirs
• Fluidizing sheets
• Industrial dust collection filters
• Pneumatic mufflers
• Water purification filters

GUR  "Micropowders" are excellent candidates for additives in paint and coatings applications. Some benefits that are provided by these micropowders are:

• Excellent mar and abrasion resistance
• Improved impact strength
• Improved dynamic coefficient of friction
• Good binding and interphase connections
• Increased thermo-dimensional stability and high elasticity
• Surface texture
• Improved chemical resistance
• Reduced affinity for water and moisture absorption
• Broad application temperature range
