Nope, AFAIK all hard 'plastic' filters are CR39, Chromatic Resin. 
I write 'plastic' between brackets because in Dutch 'plastic' mostly
refers to thermo-plastic, a material that can be melted and deformed
again by heating. 
Resin cannot be melted again, it will get charred (carbonized?)
instead, or might finally burn (though thermo-plastics will finally
burn as well).
