Screen Film Roller Size 4 Inch 20W Description: A durable silicone roller designed for precision surface treatment and film application in electronics and display production. Built from silicone, aluminum, plastic, iron, and adhesive, this roller offers a stable fit between film and substrate, consistent performance, and long service life for repeated use in PCB, LCD, SMT, and related processes. Key benefits: Precise film contact: Silicone roller surface conforms to the target surface for better control during film lamination, printing, and surface finishing. Durable construction: Tested to roll 60,000 times without peeling, with a melting point of 150 C and materials that are water insoluble for reliable performance in production environments. Non viscous, non stick surface: No surface viscosity to leave residue on films. Note this product is not anti static and is intended only for removing small dust particles. Stable hardness: Shore hardness 45 provides the right balance of resilience and firmness for consistent pressure and reduced surface damage. Easy maintenance: After use, roll the roller back and forth on sticky dust paper several times to remove particles and restore the surface. Key specifications: Size: 4 Inch 20W Item type: Screen Film Roller Materials: Silicone, aluminum, plastic, iron, glue Melting point: 150 C Water solubility: Insoluble Peeling test: 60,000 rolls without peeling Surface hardness: Shore hardness 45 Viscosity: No viscosity Inner / outer diameters: Roller outer diameter approx 28 mm / 1.1 in; bearing outer diameter 13 mm / 0.51 in; bearing inner diameter 6 mm / 0.23 in Package: 1 x Screen Film Roller Typical applications: LCD assembly: Remove dust and ensure uniform contact when laminating protective films or polarizers onto LCD panels. PCB and SMT handling: Aid in applying film masks, protective sheets, or light guide films during electronic assembly and inspection. Soft sheet printing and light guide sheet processing: Improve surface contact and control during printing, cutting, or finishing of soft sheets and optical films. Usage notes: Use for removing fine dust particles only. This roller does not provide anti static protection. Clean by rolling on adhesive dust paper until surface is of particles. Store away from direct heat above the rated melting point. This Screen Film Roller is suitable for production and tasks in electronics, semiconductors, PCB, SMT, LCD processing, light guide sheet handling, and soft sheet printing where controlled film contact and repeated use are required.
