Thermoflux MPM

THERMOFLUX MPM is a semi-flexible, heat shrinkable tubing with an integrally bonded meltable sealer inner lining designed to provide permanent moisture-proof encapsulation for a wide range of applications. The inner wall melts when heated and is forced into interstices by the shrinking of the outer wall, so that when cooled, the substrate is encapsulated by a tough protective, moisture-proof barrier. An operating range for -60°C up to 145°C and a shrink ratio of 3/1 as standard means that the tubing offers superior environmental protection to a wide range of irregular shapes with different dimensions.

  • Consists of two layers.
  • Outside layer shrinks - inside melts and seals making it perfectly waterproof.
  • Excellent bonding and sealing characteristics.
  • Moulds to most irregular shapes.
  • Easy to apply with gas torch or hot air gun.
  • Excellent resistance to chemicals, acids and alkalines.
  • Flame retardant - resists UV-light.
