Phenolic sandwich panel performance full as the unique properties of rock wool material, with high effect for fire-resistance, thermal insulation, acoustic insulation and other aspects.
1.Fire-resistance: Uses raw materials, production process and formulation, phenolic sandwich panel has good fire-resistance.
2.Thermal insulation:The sandwich thermal insulation performance based on phenolic thermal conductivity, testing according to corresponding proportion thickness phenolic the calculation obtained.
3.Acoustic insulation : At the same time, the phenolic 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 rockwool sandwich panel meets DELTA LA=15.7Db(A)
