Parylene N and C have a low degree of crystallinity; however, parylene VT-4 and AF-4 are highly crystalline ~60% in their as-deposited condition (hexagonal crystal structure) and therefore are generally not suitable as optical materials. Parylene C will become more crystalline if heated at elevated temperatures until its melting point at 270 °C.
