Product description and advantages

  • Diaphragms for PV module manufacture
  • Special covering layer (black) on silicone backing (grey)
  • Bond of the two layers cannot be separated mechanically
  • Black covering layer is resistant to decomposing outgassing during lamination process
  • Durability results in longer machine running times and thus shorter set-up times
  • Constant quality thanks to quality management

Lamibran® is a specially developed membrane consisting of a silicone backing material and a unique covering layer. This covering layer is extremely resistant to outgassing and related decomposing processes of EVA films. This makes Lamibran particularly durable and increases your machine running times.
