Are acetal and Delrin the same?
Delrin is a type of acetal homopolymer and therefore generally interchangeable with others of the same class. This means that Delrin still offers the same core benefits of general acetal plastics, such as: Excellent dimensional stability. Friction, fatigue, and abrasion resistance.
Is Delrin acetal copolymer?
Delrin® is an acetal homopolymer and has a uniform backbone with a larger crystalline block structure than acetal copolymers providing better chemical bonding. As a result, Delrin® is the stiffest and strongest unreinforced technical engineering polymer available.
How much does acetal cost?
Acetal resins (polyoxymethylene or POM) are engineering thermoplastics based on formaldehyde polymerization technology….0.030″ X 24″ X 24″ Black Acetal Sheet.

Does Delrin shrink?
For Delrin® standard grades, a mold temperature of 80–100 °C (176–212 °F) is recommended as good compromise. For high precision parts, a higher mold temperature up to 120 °C (248 °F) might be necessary. Note: High mold temperatures and thick part sections may increase shrinkage.
Can Delrin be machined?
It’s true that Delrin is an easy material to work with in terms of machining. It is a very stable material, which makes precise, tight tolerances easier to achieve for this thermoplastic. While machining, keep in mind that Delrin is sensitive to heat at or above 250 °F (121°C).
Can you tap holes in Delrin?
We tap a lot of delrin without any problems by just using standard machining practices. If this is a blind hole you will need to peck tap about . 3 away from the bottom and finish by hand tapping, I would peck tap at about . 25 per peck just to clear the chips and also have your rapid at about .
Where can I find Delrin 500T nc010 datasheet?
This datasheet of Delrin® 500T NC010 from DuPont Engineering Polymers is provided by the international plastics database CAMPUS .
What are the physical properties of Delrin acetal?
Common features of Delrin® acetal resins include mechanical and physical properties such as high mechanical strength and rigidity, excellent fatigue and impact resistance, as well as resistance to moisture, gasoline, lubricants, solvents, and many other neutral chemicals.
What kind of resin is Delrin 500T used for?
Delrin® acetal resin typically is used in demanding applications in the automotive, domestic appliances, sports, industrial engineering, electronics, and consumer goods industries. Delrin® 500T is a toughened, medium viscosity acetal homopolymer resin for injection molding with impact resistance similar to Delrin® 100.
What are the different grades of Dupont Delrin?
The various grades of DuPont ™ Delrin ® acetal homopolymer resins offer levels and combinations of performance, molding productivity and design flexibility. Current features include low emission homopolymer grades, medium-high viscosity acetals, grades with food contact compliance, and grades for healthcare applications.
