THERMOFLUX is a flexible, heat shrinkable dual wall tubing with an integrally bonded meltable adhesive inner lining, designed to provide permanent moisture proof encapsulation to a wide variety of substrates and uses.
THERMOFLUX has a unique inner wall which melts when heated and is forced into the crevices and interstices by the shrinking of the outer wall. When cooled the entire mass becomes a flexible, tough homogeneous covering with a controlled wall thickness.
THERMOFLUX is manufactured from radiation cross-linked polyolefins.
THERMOFLUX shrinks to 1/3 of its supplied diameter and thus only a few sizes (8) are required to cover a full range of irregular shapes in a wide variety of applications.

  • Consists of two layers.
  • Outside layer shrinks. Inside layer of adhesive melts.
  • The adhesive seals the connection completely, making it strong and perfectly waterproof.
  • Excellent corrsion, U.V., water, chemical and acid resistance.
  • Can be applied directly to copper.
  • Durable.
  • THERMOFLUX moulds to any shape.
  • Fast, simple and safe to use.
  • Flame retardant and permanently flexible.
  • Easy to apply.
