I really have no idea other that it is one of the acrylic family.
It came from a commercial source and was butt-welded onto the material I was buying but no-one can tell me why it was welded on or what it was.
It looks absolutely nothing like the material I was buying and ironically, I was short-changed on the rod length I was buying the balance of which was made up of this stuff.
In reality, the rod I was buying is not a patch on this stuff.
Its a funny old world...
Guess its going to be a very limited edition!!!
