TECAFIL POM-C natural - 1,75 mm


POM filament, also known as acetal filament, is manufactured by Ensinger under the product name TECAFIL POM-C natural. This POM filament is based on the polymer polyoxymethylene as a copolymer, which is why it is specified as POM-C. Like polyamides, it is categorised as a technical filament. 
In contrast to POM-H (homopolymer), POM-C filament offers the advantage that the melting point is lower. Moreover, it has a higher abrasion resistance and higher impact strength.
Parts made from this POM filament are heat resistant up to 100 °C (continuous operating temperature) and can withstand low temperatures down to -40 °C. Overall, POM filament is known for its chemical resistance and good hydrolysis resistance up to approx. 60 °C. Low moisture absorption as well as high dimensional stability and excellent toughness (even at low temperatures) ensure that acetal filament is also suitable for printing parts in contact with water, e.g. in outdoor applications.
The only limitations are UV resistance. A very low coefficient of friction and high abrasion resistance make POM a suitable material for sliding applications such as rails or bearing bushes and general use in mechanical engineering.
POM is one of the most widely used plastics in the food and packaging industries. It is therefore also in high demand for food processing applications.
The base polymer of this filament meets the requirements for food contact according to (EC) No 1935/2004, (EU) No 10/2011, (EC) No 2023/2006 and FDA. Migration tests according to EU 10/2011 were successfully performed on similar extruded specimens. Legally binding documents must be requested separately.
When 3D printing POM, make sure that the temperature does not exceed 240 °C under any circumstances, as the filament can burn and release dangerous formaldehyde at the same time.
POM filaments tend to warp due to their semi-crystallinity. Therefore, we recommend a high print bed and chamber temperature.
