Rosin for light
yellow to yellow red transparent solid, softening point ℃, a
proportion of *0 to *0 1.**0 ~ 1.**5, RongXieRe: *5.8 kcal/kg, heat
capacity: 0.*4 kcal/kg, ℃, coefficient of thermal conductivity:
kcal/m 0.*1, h. ℃, volume resistivity: 5 x ***6 &branded; cm,
flash point: **6 ℃. Rosin also has crystallization properties, easy
to produce the crystallization phenomenon, in acetone, etc will
have crystallization trend, crystallization critical temperature of
about **0 ℃, crystallization rosin melting point ℃ **0 ~ **5, and
it is very difficult to be saponification. In addition, rosin also
has rotatory sex, flux than spin value control in 0 ~ *5 ° between
(best points + 7 °) which is no crystallization phenomena and
crystallization trend of the lowest rosin.
