What is it

Delrin is a lightweight, low-friction, and wear-resistant thermoplastic with good physical and processing properties and capable of operating in temperatures in excess of 90 degrees celsius (approximately 200 degrees fahrenheit).

Delrin can have a thickness tolerance (variation) of up to +/- 10%. We do our upmost to provide the median thickness here.

Orders using this material generally ship in 1-2 weeks. Find out more.

Design notes

Delrin is supplied to us without protective covering and is prone to scratching. This is more apparent on black. Acrylic is a good alternative if considering making an 'appearance' product.

Typical uses

Wheels, guitar picks, handles.

Adhesives, joints & fastenings

Delrin is very difficult to bond using solvents. It is possible to bond using a combination of surface treatments and expoxy or polyurethane adhesives. It is possible to bond by melting.

** A warning about the finish of the Derlin material:

Typically it is used for engineering type products such as washers and gaskets, and as such it often has a level of light surface scratching when it arrives from our supplier. These scratches resemble those you often see on the surface of well-used CDs.

This has not come across in the images because the lighting conditions didn’t allow them to stand out, but they are visible to the eye - not so much with the White Derlin as with the black, however.

Just noticed I only posted this info to black Delrin tips:

The thicknesses are currently wrong when viewed in metric. Until the conversion code is fixed, switch to imperial measurements to get the correct thickness to three (3) significant digits. For example: 1mm is 1/32", 2mm is 3/32".

I had originally fab'd a design in "2mm" with the intention of building a stack of three layers up to 6mm. My "Plan B", given the real thicknesses, is to stack seven "1mm" (actually 0.813mm) layers to get close to 6mm without overshooting my 6mm target. I'm framing with two layers of 3mm acrylic which IS proper metric thicknesses.

My measurement is about .65mm for a single 1mm sheet.

Looking for something like this, but flexible for light diffusion. Any suggestions?

Anyone know how flexible this material is? Or how rigid rather? I need to know at different thinknesses.

Also have the thickness issues been resolved? It now shows .8mm as the smallest one. To make a 3d object that uses a slot to fit pieces together, we need to know the exact actual thickness.

Hi Badweasel!

Thanks for checking on this. Delrin has a similar rigidity to acrylic, but is less brittle.

The 'flexibility' of a material is a hard thing to quantify and depends on the size and geometry of your design. The best thing you can do is prototype your design in a specific material/thickness and assess the results.

Regarding thickness, all sheet materials have a thickness tolerance - or potential variation in thickness from what is listed by the manufacturer. In the case of Delrin this is around +/- 10%. The best thing you can do is ensure the vital dimensions required to connect your parts together are ones you are cutting. You can find out more about interlocking plastic designs here:

Mrjudkins, can you comment on the rigidity of delrin vs bamboo?

Hi Jean-Philippe - you're probably best to get a couple of samples in your hands and assess for yourself:
