Acetal or Polyoxymethylene (POM). also commonly known under DuPont’s brand name Delrin®. is an engineering thermoplastic. It is a lightweight, low-friction and wear-resistant material with good physical and processing properties. There are two types of Acetals: Copolymers or Homopolymers.

Emco Plastics is a supplier of many types and specifications of acetal rod, tube, and sheets. We are one of the top suppliers in the United States offering nearly all configurations, colors, sizes, and options. Since we stock our warehouse with industrial plastics, chances are we have the plastic you need and can ship to you quickly and cost effectively!

Emco often buys in large quantities, offering acetal sheets and other types of plastic at wholesale pricing. If you are looking for a rod supplier, Emco also has you covered, with the largest selection of rods on the East Coast. We offer custom quotations on all of our products and can custom machine any items you need.

Types of Acetal

Unfilled Copolymer

Acetal (Copolymer) is a tough, stable thermoplastic offering a unique combination of properties which include high modulus of elasticity, high strength, rigidity and dimensional stability. Copolymer acetals can accept reinforcement much better than the homopolymer.

Unfilled Copolymer
Sustarin C

Sustarin® C copolymer has a number of benefits, including strength, tenacity, and toughness in a 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
Pomalux

Pomalux® is a high performance acetal copolymer that has excellent mechanical, electrical, and wear properties. It is engineered to provide outstanding dimensional stability, even machining parts with complex geometries.

Pomalux
Acetal Machining & Fabricating

Acetal is a rigid, strong material that is available in copolymer and homopolymer compounds. Its properties include low moisture absorption, good chemical resistance and good dimensional stability

Acetal Machining & Fabricating
Homopolymer Unfilled

Homopolymer acetal is most commonly recognized as Delrin, resins that are currently made by the DuPont Company under the trade name Delrin®AF. Homopolymers have slightly higher mechanical and thermal properties than Copolymers.

Homopolymer Unfilled
Delrin Machining & Fabrication

Using the latest technologies and highest quality standards, we can machine & fabricate Delrin into fittings, gears, seals, gaskets, wear parts, rollers and more.

Metal Detectable Acetal

This copolymer 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 (results may vary depending on the sensitivity of the metal detection system used).

Metal Detectable Acetal
PTFE Filled Homopolymer

PTFE fibers uniformly dispersed in Delrin®AF Acetal resin offers better wear characteristics than unfilled Delrin®AF Acetal, particularly for use in moving parts in which low friction and long wear life are important

PTFE Filled Homopolymer
Tecaform AD Copolymer

Tecaform® AD is a versatile engineering plastic with high strength and dimensional stability.

Tecaform AD Copolymer
Static Control Copolymer

This non-carbon filled acetal contains a permanantly static dissapative material designed for use where electrical discharge in operation is a problem. Additives such as carbon fibers, stainless steel fibers are all used to modify the electrical resistivity of acetal resin so that static charge can dissipate safety through the material.

Static Control Copolymer
Glass Reinforced Homopolymer

15% or 20% glass fiber filler provides much greater mechanical properties over unfilled acetals.
