Fluoropolymer prevents pollution of products by elution.
In general, fluoropolymer is extremely inactive material, and is used to avoid metal ions in a form of fluoropolymer coating film.
The amount of metal ion elution depends on your [operating conditions], [fluoropolymer coating material], [coating application specification] and [coating application environment], and even with high purity (for elution prevention), each user has different operating condition and different elution order threshold.
Nippon Fusso offers fluoropolymer coating technology based on [coating material selection], [film structure], [coating application in clean room] which are developed through usage at semiconductor device maker, equipment maker and fine material maker. Seek advice from our sales team.
