Siloxane compositions are useful as traction fluids in traction drive systems which are subject to varied operating temperature and pressure conditions. Specific siloxane compositions included contain units of formulae n (VII) (R 3 SiO 1/2 )(RSiO 3/2 )(SiO 4/2 ), n (VIII) (R 3 SiO 1/2 )(RSiO 3/2 ), n (IX) (R 3 SiO 1/2 )(SiO 4/2 ), n (X) (R 3 SiO 1/2 )(R 2 SiO 2/2 )(RSiO 3/2 ), n (XI) (R 3 SiO 1/2 )(R 2 SiO 2/2 ), and n (XII) (R 2 SiO 2/2 ) a n in varying mole percents, where a is an integer ranging from 3 to 20 and each R is independently selected from alkyl groups comprising 1 to 18 carbon atoms and aryl groups comprising 6 to 18 carbon atoms. |
