rosin for light yellow to yellow red transparent solid,
softening point of 70 ~ 90 ℃, specific gravity of 1.070 ~ 1.085, the RongXieRe: 15.8 kcal/kg,
the heat capacity: 0.54 kcal/kg · ℃, the coefficient of thermal conductivity: 0.11 kcal/m · h · ℃,
the volume resistivity: 5 x 1016 Ω cm, flash point: 216 ℃. Rosin also has crystallization
properties, easy to produce the crystallization phenomenon, in acetone,
etc will have crystallization trend, crystallization critical temperature of about 100 ℃,
crystallization 110 ~ 135 ℃ rosin melting point, and it is very difficult to be saponification.
In addition, rosin also has rotatory sex, than spin value control rosin in 0 ~ 15 ° between
(the best point + 7 °) which is no crystallization phenomenon and crystallization of the lowest trend rosin.
