Delrin is a Dupont Trademarked engineering thermoplastic (it is a form of Acetal) used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. I don't believe it contains any additional (IOM non-compliant) compounds to provide its strength and wear resistance. see https://www.dupont.com/brands/delrin.html

It is available in the US from several places such as MPI https://www.maxxprod.com/mpi/mpi-15.html Price is $130 plus shipping ($8). You may well get charged import VAT duty and a PO handling fee (£8) that could well total about £30
