Hi there!

I need price information for the following materials, these are necessary for the concentrated solar thermal power generation project that I need to start. Here they are:

PBS pigment with silicon binder
copper-chromium oxide pigment,ethylene-propylene diene monomer binder
acrylic (plexiglass)
Kinglux
UCON 500 (union carbide)
Caloria HT 43 (Exxon)
3M scotchcal 5400
3M FEK-163
Alzak

Re: materials price information

Heres some more information on these materials:

selective paints

absorptance emittance Temp (`C)
1) PBS pigment with silicon binder 0.90 0.37 350

2) copper-chromium oxide pigment,
ethylene-propylene diene monomer 0.92 0.30 not known
binder

cover
acrylic (plexiglass)

index of refraction = 1.49

shortwave transmittance = 0.90

longwave transmittance = 0.02

Density = 1189 kg/m3
Thickness = 3.175 mm
Max Temp = 93 `C
Cost = $9/m2

3) Reflective sheet

metallized plastic films

i) 3M scotchcal 5400

Relative weight R1 = 0.86
Hemispherical reflectivity Rs(2pi) = 0.85

ii) 3M FEK-163

Relative weight R1 = 0.86
Hemispherical reflectivity Rs(2pi) = 0.86

iii) Alzak
Relative weight R1 = 0.66
Hemispherical reflectivity Rs(2pi) = 0.85

Only 0.66 of the light incident on kinglux is reflected even
though hemispherical reflectance is 0.85

4) Kinglux

Relative Weight R1 = 0.65

Hemispherical refectivity Rs(2pi) = 0.85
Only 0.65 (ie 65%) of the light incident on the kinglux is
reflected to the absorber even though hemispherical reflectance is 0.85

Cost = $8 - $35/m2

5) HTF (Heat Transfer Fluid)

Polyglycol

i) UCON 500 (union carbide)
Freezing point = -37 `C
Boiling Point = 289 `C (max temp)
Thermal conductivity = 0.15 W/mk
Specific Heat = 2.2 kJ/kg.K (at 100 `C)

ii) Paraffinic hydrocarbon
Caloria HT 43 (Exxon)
Freezing point = -9.5 `C
Boiling Point = 311 `C
Thermal Conductivity = 0.13 W/mK
Specific Heat = 2.1 kJ/kg.K (at 100 `C)

Re: materials price information

Any help on finding out the prices of these materials would be greatly appreciated.

Thanks!

Re: materials price information

Your questions are not those we deal with much on this forum...

And I assume you would like the materials to be delivered/available in Pakistan?
