McMaster-Carr carries what to me is the equivalent (I have purchased large sheets of the stuff).
See http://www.mcmaster.com/#garolite/=i38d13
They call it Garolite
Bakelite is named for Leo Baekeland who invented the stuff. Us physics types used a ton of it over the years as it machines easily, does not dull cutting tools. http://en.wikipedia.org/wiki/Leo_Baekeland
Here are collections of items made from the stuff

A book on its properties

Subject: Re: [TN] DH 99 Bakelite laminate
Bakelite is/was a brand name for one of the earliest synthetic polymers,
it's a phenolic resin.
It's likely that what is meant by 'Bakelite laminate' is paper phenolic,
Bakelite being a brand name that tended to be used as a generic term. (like
Gas , Xerox, Hoover etc)
Early PCBS were made from layers of paper impregnated with phenolic resin,
and was replaced by glass epoxy years ago. It lingered in mass market stuff
into at least the late 1970s as it was cheap. FR2 would likely be a
functional equivalent, a proper PCB guy would probably know, but you might
need to find an old timer to understand the question. Or try googling of
course!

Subject: [TN] DH 99 Bakelite laminate
Hi TechNet,
Does anyone know if DH 99 Bakelite laminate is still available, or what
a modern equivalent might be ?
The drg that specifies it is dated 1973, and is for an Antenna of some
type.
Many Thanks
