Delrin Rod – Strong, Smooth, and Built to Last

Delrin rod is an excellent choice if you need a rugged, reliable plastic that’s easy to machine and holds up under pressure. It’s a type of acetal homopolymer with slightly better mechanical properties than standard acetal copolymer. Thanks to its strength, low friction, and resistance to wear, Delrin is used in everything from industrial machinery to automotive parts and medical equipment.

​

Why Choose Delrin Rod?

It’s Strong and Holds Its Shape
Delrin is one of the strongest plastics available. Its high stiffness and impact resistance make it resistant to bends and deformations. Delrin is an excellent option if you need a material that can withstand repeated use and heavy loads without wearing out.

​

It’s Smooth and Low-Friction
One of the best things about Delrin is how smoothly it moves against other surfaces. It has a naturally low coefficient of friction, meaning it won’t cause unnecessary drag or resistance. That’s why it’s commonly used for gears, bearings, and bushings—parts that need to slide or rotate smoothly without wearing down too quickly.

​

It Won’t Absorb Moisture or Swell
Unlike some other plastics, Delrin doesn’t absorb much water. This means it won’t swell or lose shape in humid environments or when exposed to liquids. Delrin is an excellent choice if your project requires tight tolerances and precision because it stays dimensionally stable over time.

​

It Resists Chemicals, Fuels, and Oils
Delrin is well-resistant to fuels, oils, solvents, and many industrial chemicals. This makes it ideal for automotive and mechanical applications, where exposure to these substances is daily. Delrin also holds up under harsh conditions, whether used in fuel system components or machine parts.

​

It’s Easy to Machine and Work With
Delrin is one of the easiest materials to work with if you need to cut, drill, mill, or shape plastic. It machines cleanly, ensuring smooth edges and precise results without wearing down your tools too quickly. Whether you're using CNC machining or manual fabrication, Delrin is an excellent material.

​

It’s Food-Safe and Used in Medical Equipment
Some grades of Delrin meet FDA and food safety standards, making it an excellent option for food processing machinery, conveyor systems, and cutting surfaces. It’s also used in medical devices and surgical instruments because it can withstand sterilisation and is resistant to bacterial growth.

​

Where Is Delrin Rod Used?

Delrin is used in a wide range of industries because of its unique combination of strength, smoothness, and durability. Some typical applications include:

​

Gears and Bearings – Reduces friction, operates smoothly, and lasts long.
Seals and Bushings – Stays dimensionally stable, even in humid or wet environments.
Medical Equipment – Used in surgical tools and other sterilised components.
Automotive Parts are commonly found in fuel systems, door mechanisms, and other precision parts.
Marine and Outdoor Equipment – This does not absorb water, making it perfect for marine applications.
Food Processing Machinery – Safe for food contact and resistant to contamination.

​

Available Sizes and Colours

Delrin rods come in various diameters and lengths to suit different needs. The most common colours are natural (white) and black. If you need a specific size, most suppliers offer custom-cut options to match your exact specifications.

​

Is Delrin Rod Right for Your Project?

Delrin rod is an excellent choice if you need a strong, smooth, and long-lasting plastic that’s easy to work with and performs well in demanding environments. Whether you’re making gears, machine parts, or food-safe components, Delrin offers a great mix of durability, precision, and low maintenance.
