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

    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?
