PU sandwich panel performance full as the unique properties of PU material, with high effect for water-resistance, thermal insulation, acoustic insulation and other aspects.
Characteristic:
1.Nonflammable. Little shrinkage under ultra-low tempearture, not brittle, most suitable for cold storage.
2.Thermal insulation:The sandwich thermal insulation performance based on PU thermal conductivity=0.043W/,testing according to corresponding proportion thickness rock wool the calculation obtained.
3.Acoustic insulation : At the same time, the PU sandwich panel performed with good acoustic insulation, it absorb sound within a relatively wide frequency range. According to ISO 35/85 standard, acoustic performance level of PU sandwich panel meets DELTA LA=15.7Db(A)
