| Product Description | ||||
|
Parylene HT, the newest Parylene commercially available, replaces the alpha hydrogen atom of the N dimer with fluorine. This variant of Parylene is useful in high temperature applications (up to 450°C) and those in which UV stability is requred. Parylene HT also has the lowest coefficient of friction and dielectric constant, and the highest penetrating power of the four variants.
