tesa® 4582

High Adhesion Venting Tape

  • The high adhesion level achieves a perfect hold on various production circumstances
  • The good permeability for air and other gases allows the foam to fill the entire body resulting in an optimal thermal insulation
  • The permeability is homogeneously spread for efficient processes and constant foaming results
  • Works excellent as a barrier against foams to decrease foam leakage and cleaning effort
  • Unwinds gently to avoid curling which makes the handling easier in order to reduce process time
  • Comes without a liner to reduce the general waste in production sites
  • Easily torn by hand for an increased working efficiency
  • Is conformable to shaped structures
  • Allows an exchange of moisture and other gases
  • The specific coating structure of tesa® 4582 achieves a very high adhesion level while maintaining good air permeability.

Product description

tesa® 4582 is a single-sided tape for venting applications. It is based on a nonwoven fabric coated with a specific pattern to partly cover the backing. The homogeneous spread of adhesive ensures constant venting performance.

Application Fields

The venting tape is used to cover holes during foaming processes in different industries

  • Designed for appliances where the foam is used to insulate fridges and freezers, as well as to stabilize the body
  • In production of special vehicles such as refrigerator trucks
