The blanket is constructed of mulitple layers of material:
Kevlar C21H15N3O3
Nextel Al2O3 (62.5%) SiO2 (24.5%) B2O3 (13%)
Solomide Foam density = 0.005 g/cm3 Nor chemical formula is provided, we'll assume CH
MCI&Handling Layers density = 1.4 g/cm3 From the description sounds like mostly Kapton (C22H10N2O5)
The top has an area density of 32328 cm2.
The thickness can be comuted as:
MCI MCL&Handling Layers: 0.07 cm
Solomide Foam: 4(0.65 cm)
Nextel: 4(0.043 cm)
Kevlar: 6(0.03 cm)
Total: 3.02 cm
