CMC 61325 is a laminating film based on a 25 µm PEN carrier film, equipped with a heat-seal adhesive on a polyester resin base. It is delivered with a PE protective cover. The recommended lamination temperature is from 120°C to approximately 180°C, with adjustments in pressure and dwell time required at lower temperatures to achieve the same sealing result. It is RoHS and REACh compliant, offering high electrical insulation properties with a breakdown voltage of at least 6000 V, and mechanical strength with a tensile force of at least 30 N/cm and elongation of at least 50%.

Use Cases

  • Typically used in hydrogen and related industrial applications

Capabilities

  • Laminating film with polyester resin-based heat-seal adhesive
  • Protective cover made of PE
  • Recommended lamination temperature from 120°C to approx. 180°C
cmc Klebetechnik GmbH CMC Klebetechnik GmbH, founded in 1998 and based in Frankenthal, Germany, is a manufacturer and coater of technical adhesive tapes and films that has developed specialized sealing solutions for PEM fuel cells and PEM electrolyzers over more than five decades of coating expertise. The company's CMC 61145 adhesive film (hydrolysis-stable PEN carrier film with acrylate adhesive) and CMC 15141/15142 (PPSU-based) sub-gasket films seal the membrane electrode assembly (MEA) subframe, preventing hydrogen/oxygen media crossover while providing electrical insulation, mechanical stability, and facilitating automated roll-to-roll MEA assembly. CMC's adhesive films are designed for durability in demanding fuel cell applications such as electric buses, heavy goods transport, and decentralized power supplies, with hydrolysis and solvent resistance suited to the acidic, humid stack environment. The company was awarded the Bronze Medal in the EcoVadis sustainability assessment and supplies customized film materials, adhesives, and die-cut parts for hydrogen technology, e-mobility/battery, and broader electrical engineering applications.
