Which country paper currency cannot be torn and burnt?

I know of two countries that have replaced paper currency with a plastic currency that is extremely hard to tear, and which if subjected to high temperature will melt rather than burning. Australia has this, and Canada is in the process of adopting it (in the sense that plastic $100, $50, and $20 bills have been issued, but $10 and $5 bills have not yet been issued in the new format). The new type of currency is more durable, and harder to counterfeit.
