摘要：
Compositions based on PTFE, homopolymer or modified, comprising for 100 parts of the component 1) PTFE:
1) an aqueous nanodispersion of said homopolymer or modified PTFE, having a primary particle diameter from 5 to 100 nm;
2) from 3 to 45 parts by weight of a surfactant or surfactant mixtures;
3) from 0.2 to 20 parts by weight of an organic or inorganic sequestrant,
and optionally:
4) from 0 to 60 parts by weight of a solid lubricating compound.
