Material Notes:
Description: Polyester films have excellent dimensional stability, high tensile, tear, and impact strengths, and ultimate elongation up to 120% of its original dimensions. These films exhibit low water absorption and good resistance to oils, greases, strong acids, and organic solvents. They also retain electrical properties, dielectric strength, and dielectric constant in continuous operating temperatures from -100°F to 350°F (-73°C to 177°C). Applications include transformer and capacitor wrapping, printed circuit board fabrication, splicing tapes, composite bonding protection, and low-cost masking. This tape uses a natural rubber adhesive system. Natural rubber adhesives impart high tack and shear characteristics. These adhesives perform in continuous operating temperatures from -20°F to +325°F (-29°C to +164°C). Natural rubber adhesives can be specially blended to manufacture a broad range of adhesive performance from a low adhesion of 3.0 oz./in. to a high adhesion of 60 oz./in. All data based on a 0.003 inch test sample.(Thickness given is for both backing and adhesive. Backing thickness is .001 inches.) Information provided by Saint Gobain Performance Products.
