- 1. What is the difference between Delrin and acetal?
Delrin is a specific brand of acetal homopolymer made by DuPont. Acetal is a broader term that includes both homopolymers and copolymers. It generally has higher strength and stiffness compared to acetal copolymer.
- 2. Can Delrin bushings be used in high-temperature environments?
It performs well in temperatures up to approximately 90°C (194°F) continuously. For higher temperatures, it's best to consult with a material expert or consider alternatives. You can always reach us at sales@avenirbharat.com or call at +91-9310 916166.
- 3. Is Delrin food-safe?
Yes, certain grades are FDA-compliant and can be safely used in food processing equipment. Always confirm the grade before use in such applications
- 4. How do I know if I need a standard or custom Delrin part?
If the required part size or design is not available off-the-shelf, or if your application has unique technical requirements, a custom rod or bushing will offer a better fit and performance.
- 5. Where can I get Delrin rods and bushings at competitive prices?You can get high-quality polyacetal rods and bushings from Avenir Solutions. We offer competitive pricing, custom fabrication, and expert guidance for all your engineering plastic needs.
- 6. Is Delrin suitable for outdoor use?
It has good weather resistance, but prolonged exposure to UV radiation can degrade it over time. If outdoor use is critical, consider using UV-stabilized grades or additional protective coatings.
- 7. Can I machine Delrin with standard tools?
Yes, polyacetal is very machinable and can be worked using standard metal or wood-cutting tools. Sharp tools and proper cooling are recommended for the best results.
- 8. How long do Delrin bushings last?
The lifespan of bushings depends on the load, speed, and environmental conditions. Under proper use, they can last significantly longer than metal bushings, especially in dry or low-lubrication applications.
What is Delrin? Understanding High performance Industrial Plastics
Delrin is a brand name for acetal homopolymer, a type of thermoplastic known for its exceptional strength, rigidity, and dimensional stability. Developed by DuPont, it is widely used in engineering applications where low friction, high stiffness, and excellent wear resistance are essential. Because of these properties, it is often used to manufacture parts like rods and bushings for industrial and mechanical systems. “Delrin,” “acetal,” “polyacetal,” and “POM” are closely related terms, often used interchangeably, but they have some distinctions worth understanding.
Key Properties That Makes POM Ideal for Industrial Applications
POM offers a unique combination of properties that make it a preferred material in a wide range of industries. It has a high tensile strength and can withstand heavy loads without deformation. Its low coefficient of friction makes it suitable for moving parts like bushings, which need to operate smoothly with minimal wear. Delrin is also resistant to moisture, solvents, and chemicals, which ensures durability in harsh environments. These advantages explain why acetal rods are frequently chosen for precision-machined components.
Delrin Rod: Features, Sizes, and Applications
Polyacetal rods are solid cylindrical plastic bars manufactured from Delrin material. These rods come in various diameters and lengths, making them versatile for custom machining. Common applications of the rod include gears, rollers, spacers, and structural parts that require high strength and stiffness. Engineers and machinists prefer it for its easy machinability and ability to hold tight tolerances. Whether you’re designing a new component or replacing a worn-out part, POM rod provides a reliable solution.
Why Choose POM Bushings for Mechanical Systems?
POM bushings are widely used in mechanical systems to reduce friction between moving parts. These bushings are lightweight, corrosion-resistant, and have excellent wear performance. Compared to metal bushings, Acetal bushings offer quieter operation and longer life in many applications. They are also non-conductive, making them ideal for electrical insulation. When you need a dependable, low-maintenance solution for high-load or high-speed systems, it is an excellent choice.

Delrin vs. Other Plastics: How It Compares
While there are many engineering plastics on the market, Acetal stands out for its combination of strength, rigidity, and low friction. Compared to materials like nylon, it absorbs less moisture, which means better dimensional stability over time. It also offers superior machinability compared to UHMW and PTFE, making it easier to produce precise parts like rods and bushings. When precision and durability are crucial, Polyacetal is a material that consistently delivers.
Common Industries Using POM Rods and Bushings
POM rods and bushings are used across various industries due to their mechanical performance and reliability. In the automotive sector, these bushings help reduce noise and vibration in suspension systems. In manufacturing, POM rods are used to create jigs, fixtures, and other tooling components. Medical device manufacturers also use polyacetal for its cleanliness and dimensional accuracy. Other industries include aerospace, electronics, and food processing, all benefiting from its robust characteristics.
Custom Polyacetal Parts: When Off-the-Shelf Doesn’t Fit
Sometimes, standard parts just won’t do. That’s where custom Acetal components come in. It can be machined into virtually any shape to meet specific design requirements. Custom bushings are especially useful in applications where unique sizes or tolerances are required. Whether you need a one-off prototype or a large production run, custom acetal parts ensure you get the perfect fit and function.
Machining: Tips for Precision and Performance
Polyacetal is one of the easiest engineering plastics to machine, making it ideal for creating precision parts. Use sharp tools and avoid excessive heat buildup during cutting to maintain dimensional accuracy. When machining the rod or fabricating bushings, it’s important to account for thermal expansion and to ensure tight tolerances. Proper fixturing and cooling methods will further enhance your machining results.
