What is the Density Of Delrin? Delrin, also known as Polyoxymethylene (POM), is a thermoplastic material that is widely used in engineering applications. It has excellent properties such as high stiffness, low friction, and good dimensional stability. The density of Delrin is an important property that plays a vital role in its applications. In this blog, we will discuss the density of Delrin in detail.
What Is Delrin?
Delrin is a type of thermoplastic material that belongs to the acetal family. It was first introduced by DuPont in the 1960s and has been used in a wide range of applications ever since. Delrin is known for its excellent mechanical properties, such as high stiffness, low friction, and good dimensional stability. It is also resistant to chemicals, abrasion, and moisture, making it suitable for use in harsh environments.
Density Of Delrin
The density of Delrin is 1.41 g/cm³ or 0.051 lb/in³. This makes it one of the densest thermoplastics available. The high density of Delrin is due to its closely packed molecular structure. The high density of Delrin makes it a preferred material for applications that require high strength and stiffness.
Comparison With Other Materials
When compared to other materials, Delrin has a higher density than most thermoplastics, such as polyethylene and polypropylene. However, it has a lower density than metals such as aluminum and steel. The high density of Delrin makes it a preferred material for applications that require high strength and stiffness, but it may not be suitable for applications where weight is a critical factor.
Applications Of Delrin
Delrin is used in a wide range of applications due to its excellent properties. Its high density makes it suitable for applications that require high strength and stiffness. Some of the common applications of Delrin include:
- Gears and Bearings: Delrin’s low friction and high stiffness make it suitable for use in gears and bearings.
- Automotive Parts: Delrin is used in various automotive parts such as fuel system components, airbag components, and seat belt components.
- Electrical and Electronic Components: Delrin is used in electrical and electronic components due to its excellent dimensional stability and resistance to chemicals.
- Medical Devices: Delrin is used in medical devices due to its biocompatibility and resistance to chemicals.
