Default size &/or "Wonder" wheel, grinding disk, or blade on TS for safe cutting of acrylic light shield plastic

again

http://canadiantire.ca/browse/produc...f0c1b773a15348

is my TS. It has an 15A, 3hp, 10", 5000rpm, standard 5/8" round arbor, and
came e with a 1/8" 36-tooth carbide tipped combination blade. I also have a
10" 200-tooth alternating kerf blade I bought for plywood. I am not sure if
this m/c has anything in common wit soft-start technology.

I need to cut a new piece of that thin plastic sheet for a fluorescent light
housing I am making, as well as replace another cover have. I have to cut
them through 4' lengths. it is very thin, like 1/16"ish.

I am curious if I will ever get the need to buy any type of special
wheel/disk/blade that will fit in my TS that is designed for cutting
plastics and other non-wood materials.

I have just been to Canadian Tire and Home Depot. HD has something called a
"Wonder" disk/wheel, which abrades in chips as opposed to cuts like a blade.
Well that is the theory of grinding when it comes to metal, significantly.

Could I cut this thin prismatic pattern acrylic plastic sheet (sign says
acrylic doesn't yellow as opposed to styrene) with either of the wood blades
I already have? The plywood blade actually has the two words "WOOD" and
"PLASTIC" printed on it.

However, barring that, and assuming I now need to buy an "abrading
disk/wheel' I come to my questions:

The "Wonder" disk at HD is 8" I think, maybe 7". I didn't look at it
closely, but maybe it is a little different that a regular grinding wheel of
the (concrete/metal/cut-off) variety, and may have applications above and
beyond, regardless of its (not max of 10") size, which would allow for
future uses. I think it may have a more open structure. There are a lot of
regular grinding disks that come in lager sizes, including 10", in metal
and concrete cut-off type. They may be intended for other tools, and can/do
say on the package "for use with tools having metal guards" (like circ saws,
and grinders). In fact I am not even sure about the wonder wheel use on a
TS. So is it safe? I would say my options are either 8" (or 7") "Wonder"
wheel, or up to, & definitely including 10" 3/32" or 1/8" metal-type cut-off
grinding wheel. Could get the concrete, but probably thicker and therefor
n.a. All of the wheels have a safe max. rpm, I just checked them all. Not
sure about the guard/soft-start stuff though.
