Planigraph™ Metalbond LGPC

Composition

  • Pure flexible graphite C > 98.00 %
  • Covered on both side with 2 special polimeric films
  • Inner protection ring

Characteristics

Planigraph™ Metalbond LGPC is a gasket with inner eyelet made by pure expanded mineral graphite protected on both sides by two polimeric films. This solution allows the graphite to maintain its integrity during all the handling and punching steps guaranteeing finally gaskets capable of performing the seal with extreme efficiency. Planigraph ™ Metalbond LGPC pure graphite flat gaskets are excellent substitutes of CSF gaskets - Compressed Synthetic Fibers - thanks to their smaller creep and for their moderate sensitivity to the thermal cycles. The style Metalbond LGPC is suitable for food applications.

Applications

Planigraph™ Metalbond LGPC pure graphite gaskets are great for sealing flanges 150 to 300 psi classes. These gaskets style Metalbond LGPC thicknesses 2.0 and 3.0 mm with stainless steel inner eyelet which are suitable for application intended in contact with food applications.
