Supply Services Limited stocks a vast range of certified TECAFORM Acetal plastics that will meet and exceed your application requirements.
As one of the larger New Zealand based Acetal suppliers, our stock holding encompasses Acetal rod, Acetal tube and Acetal sheet in various sizes, colours and enhanced modified grades.
FDA and EU10/2011 food grade compliant materials are available for applications that demand it.
Acetal plastic known by its chemical name PolyOxyMethylene or POM is a semi-crystalline engineering thermoplastic. Acetal is strong, rigid and has a low coefficient of friction.
Due to its exceptional creep resistance and low moisture absorption, Acetal plastic is an excellent engineering material for parts that require a high degree of dimensional stability with low moisture absorption.
The primary properties of Acetal plastic is its high mechanical strength, rigidity, excellent wear and abrasion resistance. Acetal is resistant to a wide range of solvents but is attacked by strong acids.
There are two types of Acetal plastics for engineering available. Acetal Copolymer known as POM-C and Acetal Homopolymer known as Acetal POM-H.
Acetal POM-C and POM-H have different properties and it is important to know the difference when selecting Acetal plastic for engineering applications.
Acetal POM-C is more resistant to hydrolysis, hot water and hot air. It has higher chemical resistance and lower melting temperature. Acetal POM-H offers higher mechanical properties such as strength, creep and hardness and generally exhibits better wear resistance.
✅ High strength, rigidity and toughness with low moisture absorption
✅ Outstanding wear resistance and sliding properties
✅ High dimensional stability
✅ Good resistance to hydrolysis and creep resistance
✅ Excellent machinability
✅ Ideal material for replacing zinc or aluminium machined parts
Available in profiles such as Acetal rod, Acetal tube and Acetal sheet, the applications that this material can be used for in engineering is virtually limitless.
Common parts and proven applications that Acetal plastics are used include sliding components like bearings, bushes, gears, rollers, thrust washers and guide rails. Parts that require snap fastenings or assemblies. Electrical insulating parts and parts that require a very high degree of dimensional stability.
Acetal plastic is an excellent material for finished machined parts that require long-life or have thin-walls and require strength and rigidity.
Due to Acetal being an FDA and EU10/2011 food compliant material and aerospace approved it is widely used in industries such as mechanical engineering, food and medical technology, the oil and gas industry, aircraft and aerospace, and electronics.
Due to changes in manufacturing supply chains, food grade compliance should always be verified prior to using any material.
We commonly see Acetal plastics CNC machined into finished parts for food production equipment.
Grade dependent, the long term service temperature of Acetal is 100°C, with short term bursts up to 140°C. Acetal starts to melt at 166°C.
Copolymer Acetal (POM-C) has approx. a 10°C higher service temperature than its Acetal homopolymer (POM-H) counterpart.
The physical properties of Acetal plastics are consistent across a wide range of temperatures and humidity conditions making it a great material for high-performance parts.
Acetal is a thermoplastic with a chemical name of Polyoxymethylene or POM.
Delrin® is a brand name of DuPont™ made with DuPont resins and is an Acetal homopolymer (POM-H). Engineers who buy Acetal plastic from DuPont™ distributors will be sold Delrin®.

Stock shapes of TECAFORM Acetal rod is generally available from 3mm to 300mm diameter (grade dependent). We stock a wide range and it is best to contact our team to discuss your requirements.
TECAFORM Acetal sheet is available from 5mm to 150mm thickness (grade dependent).
We stock a range of TECAFORM Acetal tube, but the Acetal rod range on the shelf is larger as you or our machine shop can bore to your exact requirements.
TECAFORM Acetal tube ranges from 20mm ID to 505mm OD (grade dependent).
TECAFORM Acetal plastic is available in a range of colours dependent on the grade. The most common colours in stock are Natural (white), Black and Blue.
Ensinger has a vast range of grades available, so we are able to offer additional colours such as ivory, brown, green, rusted, yellow, grey and red.
Take a look at these recent food processing parts made from TECAFORM food compliant blue acetal.

Amazing material. We are seeing a big spike in food manufacturers and processors switching from white food grade Acetal plastics to vivid blue Acetals that are also food compliant.
Why? Do you see or eat much blue food? No. So the food industry is implementing vivid blue engineering plastics such as TECAFORM AH Blue Acetal that can be used with optical detection equipment to identify unwanted particulates in the food product.
See this recent blog post about food compliant blue acetal materials.
The below machined part is made from TECAFORM AH Blue and is used for a needle block in a meat processing plant.
This product is great for Acetal plastic parts that require laser marking for part identification. Do you need to track the life cycle of your parts or just to track what parts went into what machine?
Standard Acetal plastic cannot be laser marked as the top surface is translucent. With a special additive, Ensinger developed this laser markable product which can be laser marked.
Still FDA and EU10/2011 compliant. An amazing material for food engineering, medical and pharmaceutical industries.
