Acetal

Acetal, also known as POM (Polyoxymethylene), or by trade names such as Acetron® or Delrin®, is one of the most widely used engineering-grade thermoplastics in the market today. Acetal has high tensile strength, good rigidity, dimensional stability, and toughness properties that allow it to endure long-term fatigue and perform well at extreme temperatures.

Low Moisture Absorption

As a semi-crystalline material, Acetal has excellent wear and abrasion properties and a low coefficient of friction, making it ideal in both wet and dry environments. With the low absorption rate and high resistance to temperature, Acetal can be used in hot water applications up to 140°F without any hydrolysis effect.

High Tensile Strength and Rigidity

The nature of the material boasts dimensional stability coupled with stiffness and strength, resulting in minimal effect even after long-term exposure to unfavorable conditions. It also has great chemical resistance to moisture, solvents, and fuel such as gasoline. 

Electrical properties

Good electrical properties qualify these materials for electrical applications requiring long-term stability.

Ease of Machine

Acetal is an excellent choice for complex parts where tight tolerances are required. It can also be processed by conventional injection molding and extrusion techniques.

Copolymer vs Homopolymer (Delrin® 150)

ShapesPlastics offers Acetal from world-class manufacturers. Delrin®, a homopolymer, has better mechanical properties in terms of better tensile strength, rigidity, and chemical bonding, however, compared to its counterparts has centerline porosity that may eliminate it from being used in certain applications. Acetal copolymer is used widely for applications that require superior performance at high temperatures and chemical resistance. This is because of the low absorption rate that allows its physical properties to remain constant in a variety of environments. It’s a more popular material for food-grade applications. They are both FDA-approved.
