Just to correct the information in Martins original posting:
ETP (Engineering Thermo Plastics) this is not a material, it is a generic term applied to all thermoplastics that have good structural properties suitable for more demanding performance criteria.
Delrin is a brand name of DuPont and this brand has approximately 20% of the market for the material, which is Polyoxymethylene (POM) sometimes called Acetal.
If you look at a recycling logo on a moulded product it will say POM.
As DuPont is primarily American the majority of UK users will use a different brand name to Delrin.
So it is more meaningful and universal to say this platter is made of POM or Acetal.
