Plastic thermos bottle stopper with wood which heat preservation is good?
But plastic because of the difference of specific heat of different kinds is very big still, wood is also, so should not be compared directly in a strict sense, but mostly for degeneration wood structure,
In principle, the most basic, the specific heat of the two, which small which thermal conductivity is fast, so specific heat, heat preservation is good.
Wood, from real life experience, heat preservation performance is better, LZ, since to do experiments, to speak with the experimental data.
