UHMWPE

[QCJS]

Hi, does anyone know if Black Delrin is a form of UHMWPE?

Because previously a part I received from supplier A is in Black, now Supplier B delivered a white part. Designer is asking why. Do the designers have to specify the colour of the UHMWPE in their drawing?

Thanks for any help!

... seems to be POM (Polyoxymethylene), and thus, not UHMWPE (polyethylene). In case the colour is important to you then, yes, specify it.

HTH,

Hi planB,

So Delrin is POM? UHMPE can come in black or white?

Yes, Delrin is Dupont's trademark for one certain kind of POM they produce. "Black or white" is typically achieved by adding colour pigments, because polymers may have a different natural colour.
