Product Description

Ultra-pure PFA (meltable polytetrafluoroethylene) CAS 26655-00-5

Through special manufacturing processes and strict quality control, we achieve extremely high chemical purity, achieving extremely low impurity content and metal ion precipitation. 

The product is widely used in transmission pipelines, wet etching, cleaning, lithography, and other process steps in the fields of electronic chemicals, photovoltaics, semiconductors, etc. It can resist the erosion of strong acids, strong alkalis, and other chemical substances, and effectively prevent the adhesion of particulate matter.
