Plastisol is mostly a suspension of PVC particles in a liquid plasticizer that flows as a liquid and can be poured into a heated mold. For PVC plastisol applications, in addition to liquid dispersion performance and post‐dispersion flocculation resistance, outdoor durability is an important end use requirement. Spectral properties of PVC plastisol‐based films with or without additional near infrared (NIR) rays barrier fillers have been investigated. Both spherical and lamellar fillers have been incorporated in PVC plastisol at a weight content of 2% to 10% and results show a high impact on the reflectance in the NIR region and on the transmittance in the visible (Vis) region. Experimental results showed that the incorporation of nacre lamellar‐based filler in PVC plastisol did not permit favorably change its spectral properties while TiO 2 ‐based particles ensured a decrease of the transmittance in the Vis and an increase of the reflectance in the NIR.
