Abstract
Disclosed herein is a method for preparing a near infrared shielding masterbatch. The method includes the steps of preparing and compounding a composition, and then pelletizing the compounded composition. The composition includes at least one metallic ionic compound powder in an amount of about 1-25 wt %, a cross-linking agent in an amount of about 0.1-5 wt %, a thermoplastic polymer in an amount of about 67-98.7 wt %, an initiator in an amount of about 0.1-1 wt %, and a dispersing agent in an amount of about 0.1-2 wt %.
