POM Material

POM is an engineering material used in parts that require precision.Applications for POM include high performance components such as gear and fasteners(screws, nuts, washers, spacers, etc.).It is also used in other applications such as ski bindings, yoyos, watch bracelets, zippers, insulin pens and metered dose inhalers.It is used in musical instruments for picks and instrument mouthpieces, in the food industry in applications like milk pumps and coffee spigots and also as a solvent for perfumes and as a synthetic flavoring ingredient.
