POM<\/h1>\n

Polyoxymethylen (POM) ist einer der am h\u00e4ufigsten verwendeten semikristallinen technischen Thermoplaste wegen seiner einzigartigen Kombination von Unbiegsamkeit, St\u00e4rke und Ma\u00dfhaltigkeit. Dank der regelm\u00e4\u00dfigen Molekularstruktur erreicht dieses Material eine Kristallinit\u00e4t von 80 %, h\u00f6her als die der meisten anderen Thermoplaste. POM ist als Homopolymer und als Copolymer verf\u00fcgbar. Das Homopolymer hat eine h\u00f6here Kristallinit\u00e4t und damit einen besseren Verschlei\u00dfwiderstand und eine etwas h\u00f6here Unbiegsamkeit und H\u00e4rte, w\u00e4hrend das Copolymer eine h\u00f6here Verformbarkeit hat und sich einfacher verarbeiten l\u00e4sst.<\/strong><\/p>\n

POM weist bei Zimmertemperatur den geringsten Verschlei\u00df beinahe aller Thermoplaste auf. In Kombination mit der bemerkenswerten Ma\u00dfhaltigkeit eignet sich POM daher bestens f\u00fcr Zahnr\u00e4der und Lager. POM kann f\u00fcr l\u00e4ngere Zeitr\u00e4ume hintereinander bei Temperaturen bis 100 \u00b0C verwendet werden. Temperaturen bis 150 \u00b0C sind kurzzeitig zul\u00e4ssig, l\u00e4ngere Aussetzung an Temperaturen \u00fcber 100 \u00b0C verursacht eine schnelle oxidierende Degradation des Polymers.<\/p>\n

POM nimmt wesentlich weniger Feuchtigkeit auf als Polyamid: rund 0,2 % bei 23 \u00b0C \/ 50 % rLF und 0,8 % bei S\u00e4ttigung im Wasser. Das bedeutet, dass die Gr\u00f6\u00dfe eines Teils praktisch unabh\u00e4ngig von der Feuchtigkeit ist.<\/p>\n

POM ist chemisch best\u00e4ndig gegen Alkalien, aliphatische und aromatische Kohlenwasserstoffe, \u00d6le, Fette, Benzin und die meisten Reinigungsmittel. Es ist nicht best\u00e4ndig gegen starke S\u00e4uren und oxidierende Materialien.<\/p>\n

POM ist nicht UV-best\u00e4ndig, und Anwendungen im Freien sind nur mit Qualit\u00e4ten m\u00f6glich, die mit aktivem Kohlenstoff stabilisiert sind. Diese Qualit\u00e4ten werden f\u00fcr die meisten Teile von Transportsystemen verwendet. Flammhemmende Sorten sind nicht erh\u00e4ltlich.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1019","page","type-page","status-publish","hentry","entry","no-media"],"yoast_head":"\nPolyoxymethylen -
