Can you melt Delrin?
The recommended melt temperature for Delrin® is 215+/-5ºC highlighted area) at which the melt for standard grades will remain perfectly stable for over 30 minutes. For best results, machine nozzles and hot runners used with Delrin® should be set to 190ºC.
Does Delrin conduct heat?
The good electrical insulating properties are complemented by the high thermal conductivity. DELRIN: This Dupont acetal resin is made from polymerized formaldehyde and finds uses similar to nylon. KAPTON: Polyimide film has exceptionally good heat resistance and superb mechanical and electrical properties.
Is Delrin autoclavable?
Is Delrin® autoclaveable? Delrin® acetal resin survived 100 15-minute cycles of 121 degrees C (250° F) in an autoclave. However, additional cycles could result in surface chalking and hydrolysis.
Can you use acetone on Delrin?

What type of plastic is Delrin?
acetal resins
Delrin is a trademarked name for acetal resins that are semi-crystalline thermoplastic polymers. This type of material is also known by the abbreviation POM or polyoxymethylene. It has gained popularity since first being introduced to the commercial marketplace in 1960.
Can you cast Delrin?
You can mold Delrin…how do you think sheets are made? It’s cast by melting pellets and then sheeted. Acetal is often used in many parts in your cars…you’d be shocked how many acetal parts there are.
Is Delrin resistant to acid?
Delrin is not suitable for use with acids, bases, or oxidizing agents.
Will acetone melt model plastic?
The Kind of Plastic There are all kinds of plastics. If a particular plastic bears a close enough similarity to acetone, the acetone will dissolve or at least affect its surface, softening, smearing or even dissolving the plastic. Other plastics, dissimilar to acetone, will remain unaffected by the solvent.
What is the temperature range of Delrin plastic?
It provides a wide operating temperature range (-40 °C to 120 °C) and good colorability. Delrin® also mates well with metals and other polymers and offers excellent dimensional stability in high precision molding.
Why is Delrin an easy material to work with?
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).
What’s the best way to keep a delrin machine cool?
While machining, keep in mind that Delrin is sensitive to heat at or above 250 °F (121°C). Balance the material removal as best as you can to keep your dimensions stable. We also suggest non-aromatic, air-based coolants to achieve optimum surface finishes and close tolerances. Coolants have the additional benefit of extending tool life as well.
Which is better Delrin copolymer or delrin homopolymer?
Delrin ® Homopolymer Material Specifications Delrin® acetal homopolymer offers slightly higher mechanical properties than acetal copolymer, but may contain a low density center (also known as “center line porosity”) especially in large cross-sections. The homopolymer also gives slightly less chemical resistance than copolymer acetal.
