Delrin

Delrin is a registered trade name for a type of polyoxymethylene (POM), a high-performance engineering plastic. It is manufactured by DuPont and is known for its high strength, rigidity, and resistance to various chemicals, heat, and abrasion.

Overview[edit | edit source]

Delrin is a crystalline plastic that offers an excellent balance of properties that bridge the gap between metals and plastics. It possesses high tensile strength, creep resistance and toughness. It also exhibits low moisture absorption and is chemically resistant to hydrocarbons, solvents and neutral chemicals.

Applications[edit | edit source]

Due to its unique properties, Delrin is used in a wide range of industries including automotive, consumer electronics, and medical devices. In the medical industry, it is often used for small instrumentation parts, insulin pens, inhalers, and other medical devices.

Properties[edit | edit source]

Delrin has a number of properties that make it an ideal material for many applications. These include:

High strength and stiffness: Delrin has a high tensile strength and rigidity, making it suitable for load-bearing applications.

Excellent dimensional stability: Delrin exhibits low moisture absorption, which contributes to its excellent dimensional stability.

Good resistance to chemicals: Delrin is resistant to many chemicals, including hydrocarbons, solvents, and neutral chemicals.

Good wear and abrasion resistance: Delrin has excellent wear and abrasion resistance, making it suitable for parts that are subject to wear.

Health and Safety[edit | edit source]

Like all plastics, Delrin should be handled with care. It can produce harmful fumes if burned, and dust from machining can be harmful if inhaled. Always use appropriate safety equipment when handling or machining Delrin.
