TECAFORM AH LA blue is a POM-C material benefiting users through the addition of a solid lubricant additive. This addition of solid lubricant improves the sliding and frictional properties as well as the inherent wear behaviour of this POM-C LA compared to natural TECAFORM AH (POM-C). However, the addition of lubricant can compromise the strength and hardness of the material depending on the application. It still offers good chemical resistance, combined with a high degree of toughness which makes it very well suited to sliding applications.
