ACETAL MACHINED PARTS
M&P can make Acetal Machined Parts to your specifications.
MATERIAL DESCRIPTION
Acetal is a name for a family of thermoplastics with the chemical name PolyOxyMethylene.
M&P has extensive experience in machining custom Acetal parts.
Acetal is available in a general purpose copolymer grade, a homopolymer version (DelrinŽ)and several filled grades with DelrinŽ resins.
Acetal has high strength and stiffness characteristics, it has enhanced dimensional stability, and it is easy to machine.
Acetal is a semi-crystalline material.
Acetal also has a low coefficient of friction and good wear properties.
NOTABLE MATERIAL FEATURES
● High strength, stiffness, dimensional stability
● Very Low moisture absorption - Good wear and abrasion resistance
● Wide range chemical resistance (including many solvents)
GRADES OF ACETAL
ACETAL COPOLYMER (unfilled)
The copolymer grade offers excellent performance at a slightly lower cost than DelrinŽ.
Acetal copolymer may exhibit center line porosity, but porosity-free material is available.
Certain grades are FDA, USDA, NSF, Canada AG and 3-A Dairy compliant.
Low stress levels and high strength assure flatness and dimensional stability up to a maximum continuous service temperature of 180°F.
DELRINŽ (unfilled)
Acetal homopolymer offers slightly higher mechanical properties than acetal copolymer, but may contain a low density center (also known as "center line porosity") especially in large cross-sections.
The homopolymer also gives slightly less chemical resistance than copolymer acetal.
For example, DelrinŽ is ideal for small diameter, thin-walled bushings that benefit from the additional strength and rigidity of homopolymer acetal.
DelrinŽ is available in natural and black.
DELRINŽ AF (PTFE-filled) Brown
This material is manufactured from DelrinŽ homopolymer resin which has been uniformly filled with a dispersion of PTFE fibers.
DelrinŽAF is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important.
It retains 90% of the mechanical strength of unfilled acetal homopolymer, while offering very low friction.
Processing and machining of Acetal parts take place in a completely controlled environment.
We maintain a complete record of our products and build excellence into every part that is machined.
