Ticona: UHMW-PE Micro Powders for multiple applications
New micro-powder grades of ultra-high molecular weight polyethylene are being evaluated as additives that can impart anti-slip properties, abrasion resistance, impact strength, chemical resistance, and sound damping to other thermoplastics. GUR MicroPowder UHMW-PE from Ticona in Summit,USA, is a series of fine powders with average particle sizes from 30 to 60 microns. They reportedly can replace PTFE powders at application temperatures from 194 F down to - 302 F. Compared to PTFE, GUR MicroPowders reportedly show better abrasion resistance and have nearly 50% lower density, which can lead to lower costs. GUR MicroPowders are finding use in LDPE and HDPE films as anti-slip agents. GUR is said to create a roughened surface that prevents bags from sliding off piles. Initial evaluations of these powders in polyester and acetal are said to look very promising.
