Correction: LDPE is one of the lowest loss dielectrics you can use. I 
am unaware of any commercial capacitors using it. It has a rather low 
melting point and will "crack" to a rather smelly oily substance if 
subjected to corona. I used to build and run dry-fired caps which 
used LDPE. They were extended foil types and performed extremely well 
given the internal corona losses.
