SUSTARIN C®    

Acetals (POM)

Sustarin C® Acetal unfilled grades are hard, strong and stiff; have good toughness although they show some notch sensitivity. Low coefficient of friction and good chemical resistance are also standard features combined with their inherent dimensional stability.

The high crystallinity of Sustarin C® Acetals impart excellent creep resistance under continuous load and fatigue endurance under repeated loading and unloading cycles.

Sustarin C® Acetal has a number of benefits, which include strength, tenacity and toughness particularly in the temperature range of 50-120°C. As a dedicated engineering material, it is now used in applications that were once the domain of metals.

Sustarin C® Acetal can be used in "hot water" applications up to 60°C without any hydrolysis affect. Although there are few differences between homopolymer and copolymer Sustarin C® Acetals, from an application standpoint, copolymer has exceptionally good resistance to strong alkalis and hot water hydrolysis.

Sustarin C® Acetals also known as PolyOxyMethylene or PolyFormaldehyde, are available in two types, copolymer and homopolymer and both are highly crystalline linear thermoplastic polymers.

Sustarin C® Acetals exhibit predictable mechanical, chemical and electrical properties over a broad temperature range for long periods of time.

Sustarin C® Acetals, homopolymer and copolymer are available in a number of commercial stock shape grades each having specific properties. Sustarin C® Acetal Copolymer grade has the better broad range optimum benefits.

Acetal copolymer, originally developed in 1959 by Celanese Corporation is known by the trade name Celcon® / Hostaform®. Homopolymer was developed by Dupont de Nemours, known by trade name Delrin®.
