TECAFORM AH black

POM-C black

In addition to TECAFORM AH natural (POM-C), which is white in colour, a black acetal version is also available; TECAFORM AH black. ​POM-C black is a copolymer acetal material manufactured by Ensinger under the tradename TECAFORM AH black in standard stock shapes for machining, and is extruded in sheet, rod and tube​​. This POM black material exhibits good chemical resistance, high strength, rigidity and hardness as well good sliding and wear properties. Additionally this black acetal can be suitable for direct contact with food and has improved UV protection for outdoor use.
