FLEXIBLE POLYESTER FOAMS |
摘要 |
A foamed cellular material which can be obtained from foamed aromatic polyester resins with a bulk density of 50 to 700 kg/m3 by heating in vacuum to temperatures which are higher than the Tg of the material and lower than its melting point. The foamed material, generally in the form of a sheet or panel, has high-level characteristics in terms of flexibility and dimensional thermostability depending on the degree of crystallinity after the vacuum treatment
