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 (Delrin®)and several filled grades with Delrin® 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 absorbtion - 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 Delrin®. 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.A Dairy compliant. of 180°F.

DELRIN® (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, Delrin®is ideal for small diameter, thin-walled bushings that benefit from the additional strength and rigidity of homopolymer acetal. Delrin® is available in natural and black.

DELRIN® AF (PTFE-filled) Brown
This material is manufactured from Delrin® homopolymer resin which has been uniformly filled with a dispersion of PTFE fibers. Delrin®AF 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.
