Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with lubricants >5%
Blends failing 95% PTFE criterion classify by predominant monomer under 'other fluoropolymers'.
If sold as prepared extrusion aid
Mixtures exceeding simple polymer scope move to chemical preparations.
If processed into unsintered film
Non-primary forms like unsintered sheets classify as other plates/films.
