    It's because the jigsaw is running too fast and generating heat at the blade. Does it have speed control? If so, slow it down.
    A dremel will work but if you run it too fast you'll have the same problem, keep the revs down.
    Emery the edges, 240-600-1200. Do it wet (Soak the emery).

    i keep a squirt bottle with some soapy water handy, when I cut acrylic on my band saw, works like a charm, as well as lowering the speed of the blade...[as others have suggested]

    The other thing that is at work here, is that a bandsaw and a Rotozip (what I use) throw the cut plastic pieces from the work area. A jigsaw just cuts up and down - it doesn't really get rid of the freshly cut pieces like the others.

    If they are big pieces you can use a table saw with the blade reversed , also works with plexiglass , styrene and other plastics.

    This is a common problem with materials like this; matter of fact, it's something that folks in the US Air Force deal with by having saws with carbide tips, should they have to cut into a canopy to extricate a pilot.

    Perhaps carbide tipped blades aren't that rare of a thing....I know I've seen them in the civilian sector at places like Sears and such....

    You could give your friendly neighborhood dentist or orthodontist a call. They have special blades for cutting acrylic that will work for a dremel tool. You just have to put in a smaller collet. Be careful though, watch your fingers and wear eye protection.

    What do you mean "with the blade reversed" ?

    backwards, I do this all the time , if you try it the other way it will just chip and crack the plastic. This was the easiest way to cut 4x8 plastic when I had my vac-uform table.
