Spoke too soon... Here's the answer: For preventing heat from entering a car, SPD (Suspended Particle Device) film is generally considered better than high-temp PDLC (Polymer Dispersed Liquid Crystal) film because SPD is specifically designed to effectively block infrared radiation, which is the primary source of heat from sunlight, while PDLC primarily focuses on privacy by scattering light, not necessarily blocking heat as efficiently. Key points to consider: Heat blocking capabilities: SPD films are specifically engineered to significantly reduce infrared light transmission, resulting in superior heat rejection compared to most PDLC films. Privacy vs. Heat control: While PDLC can provide privacy by turning opaque, its heat blocking ability is often less effective than SPD, which can still maintain some transparency while blocking a large amount of heat. Application in vehicles: Due to its superior heat control and faster switching speeds, SPD film is commonly used in automotive applications to manage glare and temperature inside the car.
