POM, also commonly called acetal resin, is produced in the form of semi-finished products by mechanical processing and is extruded into sheets, rods and tubes.<\/p>\n
POM is a semi-crystalline thermoplastic with good mechanical strength and stiffness. Among other features it can boast: sliding and excellent wear resistance, as well as low moisture absorption.<\/p>\n
This material is able to guarantee good dimensional stability and, not least, an equally good resistance to fatigue.<\/p>\n
Even the companies that use it have considerable advantages, in fact the POM lends itself very well to machinability on machine tools, with a low cost.<\/p>\n
All this makes POM a highly versatile engineering material, even for components for medical use.<\/p>\n
Speaking of acetal resins, we must distinguish between homopolymer (POM-H) and copolymer (POM-C), since they have different properties.<\/p>\n
Thanks to the high level of crystallinity, POM-H has a slightly higher density, with greater hardness and mechanical strength. POM-C, on the other hand, has a better chemical resistance and for this reason it is used in the medical field.<\/p>\n
Summarizing the specific characteristics of the POM, we can say that the components made with this material offer:<\/p>\n
\u25cf Excellent machinability on machine tools<\/p>\n
\u25cf High mechanical strength, stiffness and toughness<\/p>\n
\u25cf Good impact resistance, even at low temperatures<\/p>\n
\u25cf Low moisture absorption (at 0.8% saturation)<\/p>\n
\u25cf Excellent wear resistance and sliding properties<\/p>\n
\u25cf High dimensional stability<\/p>\n
\u25cf Good resistance to hydrolysis<\/p>\n
\u25cf Excellent resilience and elasticity<\/p>\n
When the POM is used in the medical or healthcare field it has further advantages. It is a plastic material that is very resistant to cleaning and sanitizing agents and numerous solvents.<\/p>\n
In addition, components made of POM can be subjected to superheated steam sterilization using the most common methods in the medical industry.<\/p>\n
One of the applications in which the POM is very often used is for the production of parts of surgical instruments for orthopedic use. It is with this last application that, very often, it is used in Leghe Leggere Lavorate.<\/p>\n","protected":false},"excerpt":{"rendered":"
