Acetal plastics provide high strength and
stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-crystalline material, Acetal is also
characterized by a low coefficient of friction and good wear properties, especially in wet environments.
Alro Plastics offers both homopolymer and copolymer grades of Acetal including enhanced bearing grade materials. Acetal Copolymer
is porosity-free and offered as our standard general purpose grade. For slightly higher mechanical properties, we offer a broad
size range of the homopolymer acetal (Delrin®) products. For improved frictional properties PTFE-enhanced Delrin® AF products are
See below for the different grades available within the Acetal family of plastics.
Acetal Copolymer is the generic name for a
general purpose copolymer acetal material. This material provides the performance and machinability of acetal with
very little centerline porosity. Acetals without centerline porosity are the preferred choice for food contact and
Acetal Typical Properties
is Quadrant Plastics' general purpose copolymer acetal and is the only porosity-free acetal product available today. Acetron GP natural is FDA,
USDA, NSF, Canada AG and 3A-Dairy compliant.
ACETRON® GP Typical Properties
ACETRON® GP Natural MSDS
ACETRON® GP Black MSDS
Acetal grade, containing a metal detectable additive, has been specifically tailored for use in the food processing and packaging industries where
it can easily be traced by the conventional metal detection systems installed to detect contamination of the foodstuffs.
Acetron® MD Typical Properties
a homopolymer acetal, is also manufactured and stocked in rod and plate. It offers slightly higher mechanical properties than Acetron GP Acetal,
but may contain a low-density center, especially in larger cross-sections.
Delrin® Typical Properties
Delrin AF Blend
is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. It is a combination of PTFE
fibers uniformly dispersed in Delrin acetal resin.

WEARGEHR Acetal FG
is a wear resistant grade of Acetal copolymer. WEARGEHR Acetal FG contains a solid filler for enhanced impact, friction and wear properties.
WEARGEHR Acetal FG (Food Grade) is also FDA compliant and does not contain any PTFE in it.
