Acetal U

acetal–U is a polyoxymethylene copolymer, to which approximately 10% ultra-high molecular weight polyethylene has been added.

This addition of uhmwpe works like a dry film lubricant, and has significantly better dry and emergency running in the case of a machine breakdown with regard to non-modified polyoxymethylene.

The co-efficient of friction to steel of 0.19 is significantly lower than that of other thermoplastics (standard acetal 0.3- 0.4 / 6SA nylon 0.25-0.4).

acetal-U is therefore very suited to the manufacture of bearing bushes and sliding plates.
The uhmwpe addition gives lower noise and self-lubrication. The extremely low absorption of water of 0.14% provides an increased dimensional stability. Machine components made from acetal-U are very resistant to wear and have a high working life.

acetal-U is manufactured in accordance with the BGA and FDA guidelines in its composition and can therefore be used in the food sector.
acetal-U is light blue in colour, and other colours are available on request.
