New fluorine rubber formulation for mfg. e.g. O-rings

摘要

Fluorine rubber formulations (A) comprise fluorine rubber and a perfluoroalkane of formula F(CF2)2nF (I), where n = 5-30. Also claimed are (i) fluorine rubber formulations (B) comprising fluorine rubber and a 1H-perfluoroalkane of formula F(CF2)mH (II) (m = 10-30) and (ii) fluorine rubber formulations (C) comprising fluorine rubber, (I) and (II). Pref. (A) contains ca. 0.5-10 pts. wt. (I), (B) contains ca 0.5-10 pts. wt. (II) and (C) contains ca. 0.5-10 pts. wt. (I) and (II) per 100 pts. wt. fluorine rubber.
