Differences Between Acetal Products
There are two general types of acetal resins available: Acetal homopolymer and acetal copolymers. Each type of acetal has its own set of advantages and disadvantages. Acetal (polyoxymethylene, POM) is a thermoplastic polymer commercialized in the early 1960's. This material is produced through the polymerization of formaldehyde.
ACETAL HOMOPOLYMER resins are currently made by the DuPont Company under the trade name Acetal homopolymers offer the following advantages over acetal copolymers:
Stiffer than acetal copolymers. Higher flexural modulus at room temperature and elevated temperature applications.
Higher impact strengths at room temperatures and low temperatures.Tensile strength is approximately 10-15% higher than comparable copolymers.Slightly higher continuous use temperature than copolymer (95°C vs. 90°C).Slightly harder than copolymer acetals, thus giving the homopolymer acetals a lower coefficient of friction.ACETAL COPOLYMER (Ultraform®, Celcon®) is made by several companies including BASF and Ticona. Acetal copolymers have the following advantages over homopolymer:
Improved dimensional stability over comparable homopolymer formulations due to its lower level of crystallinity.Better chemical resistance with high pH (basic) solutions.Lower centerline porosity than homopolymer in extruded shapes.

Typical Properties of Homopolymer and Copolymer Acetals
Property	Units	Homopolymer	Copolymer
Tensile Strength @ Yield	psi	10	8.6
Tensile Modulus	psi	400	380
Flexural Strength	psi	14.3	13
Notched Izod Impact	ft-lb/in	2.3	1.5
Heat Deflection Temperature @ 66psi	° φ	336	315
Heat Deflection Temperature @ 264psi	° φ	257	220
Melting Point	° φ	347	329
Relative Chemical Resistance		Good	Better for high pH solutions

Applications
POM Rod is suitable for most non food and non highly abrasive component applications. Because POM does not absorb very much moisture, it is an engineering plastic that will suit marine applications as it also has a very low friction co-efficient and possesses exceptional sliding abilities. POM is also very good for manufacturing of many gears, because it is very good to machine and has mechanical strength and provides long life and quiet operation.
