WebOct 5, 2012 · Since most plastics have reflectance (r), of about 0.04, emissivity can be calculated for polyethylene at 3.4 microns as follows: ε = 1 - r - t = 1 -0.04 -0 = 0.96. An instrument with a spectral response of 3.4 microns is the best choice to measure temperature of thin polyethylene films. Since t decreases and emissivity increases as … WebApr 29, 2014 · Polyethylene terephthalate/high density polyethylene (PET/HDPE) composites containing a near infrared reflective (NIR, nickel antimony titanium yellow rutile) pigment was prepared using ethylene-glycidyl methacrylate-vinyl acetate (EGMA-VA) as a compatibilizer to increase the infrared reflection of PET/HDPE and limit the thermal heat …
