Scope

Scope: This document specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage requirements for ultra-thin 2μm polyimide films. This document applies to ultra-thin 2μm polyimide films (hereinafter referred to as polyimide films) made primarily from phthalic anhydride and p-phenylenediamine, and used in fields such as photovoltaic cell manufacturing and flexible display devices. Main technical content: - Surface appearance requirements: Wrinkles, indentations, and creases must account for less than 10% of the total length of the film roll, with no more than 3 defects (bubbles, thin spots, or holes). - Bubbles: Diameter ≤ 5mm. - Thin spots: Diameter ≤ 10mm. - Holes: ≤ 15mm in diameter. - Total combined defects: No more than 10 per 1,000m. - Impurities, particles, or anomalies: - Impurities: Diameter ≤ 5mm, no more than 3 per roll. - Particles: 2mm ≤ φ ≤ 5mm. - Anomalies: 2mm ≤ φ ≤ 5mm. - Total combined defects: No more than 5 per 100m. - Edge tears and notches are not allowed. - Transmission points and color deviation points: - Diameter ≥ 5mm ≤ 50mm. - No more than 5 per roll. - Slight color deviations are allowed, with a width ≤ 30mm and a length ≤ 10% of the parent roll. - No more than 3 defects (bubbles, thin spots, or holes) per side. - Appearance requirements of the film roll: - Density: Vertical placement and transportation without roll slippage or uneven ends. The end faces should not exceed their main plane by ±2mm. - Roll position: The film roll should be centered in the core, with the distance between the core end faces on either side not exceeding 2.5mm. - Tension: Both sides should be consistent, or one side may be slightly looser. - Prohibited defects: Burrs, stripes, or collapses. - Prohibited impurities: Solvent stains, white spots, black spots, scratches, stripes, or foreign objects. - Performance requirements: - Nominal t
