US source of Panzerholtz?

@923mary , Thanks for the heads up on Precision Composite Industries. I’ve been toying with a tonearm board the past month for my SME 309 on my Technics 1210 GAE. Came down to 10mm billet aluminum, but I think the Panzerholz would be the better choice for any resonance feedback into the arm.

@danmar123 As a user of a SP10 MkII seated upon a P'holz Plinth, along with a group of other users of the same TT and Plinth material, it is now mandatory to have a Phenolic Resin Densified Wood Board used a Sub-Plinth.

Panzerholz is the material generally used, but there are other options for this material from other Brands, Permali is also being used.

The material shown in the Link is available in the US, in many different colours, all info strongly suggests it is a ideal Resin Impregnated Densified Wood material, even though the weight can’t be identified as being approx’ 1400Kg/m3, or if it is a Delignified material. I would suggest to get to over a 1000Kg/m3 Delignification is occurring.

@pindac I'll look into it. The one material I'm familiar with on the site is the RICHLITE, so I'll have to do more research. Thank you 

@danmar123 I have looked at Richlite in a basic way.

It seemingly comes in at approx' 700Kg/m3

This as a weight is typical of other Phenolics produced from Paper, Cotton or Fibreglass. Compression will only seem to be enough to produce a Board that has a useful structural property.

These Types of Phenolic are usually with a damping factor not as accurate for Damping / Dissipation as is Densified Wood and the few other materials are also  comparable.

The Link will offer further guidance. 

@pindac I don't see Densified Wood on their website.
