Properties common to all products in this list

Composition: Polyester, PET, PETP Form: Metallized Film Material: Polyethylene terephthalate (PET) CAS Number: 25038-59-9 Commodity: Polymers Metallized With: Aluminum - 30 nm
PET Disk Metallized with 30 nm Aluminum combines the tensile strength, flexibility, and moisture resistance of polyethylene terephthalate with a uniform 30 nm aluminum coating that enhances reflectivity, electrical conductivity, and gas barrier performance. The precision disk format allows reliable integration into optical, electronic, and thermal control systems where consistent dimensions are critical. Industries use these metallized PET disks for capacitor electrodes, optical reflectors, and electromagnetic shielding components. Specific applications include reflective surfaces in sensing instruments, metallized dielectric layers in high-frequency capacitors, and light-management components in aerospace optics. In research, they support optical interference experiments, conductive film development, and studies on thin-metal coating adhesion and stability. The combination of dimensional precision, PET’s inherent durability, and aluminum’s functional enhancements ensures performance in advanced scientific and industrial roles.
