Syndanyo

I think you meant to type Sindanyo, but I understood anyway:)

Your best bet would be to look in the yellow pages for your nearest injection mould toolmakers, and then ring them up and ask if they have a bit spare, depending on how much you want.

Not always used on mould tools, but usually specified when we want to put heat into a tool, rather than take it out.

Builders merchants should have something similar such as masterboard or the modern equivalent of Asbestolux. If you know anyone in a university science labs/workshop you might be able to scrounge some of the genuine article.

Try this lot

I think Eternit used to produce an alternate material also but it`s a few years since I used to buy the stuff so can`t remember.
