tesa® 4582 High Adhesion

High adhesion venting tape

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.
The specific coating structure of tesa® 4582 achieves a very high adhesion level while maintaining good air permeability.
  • 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

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
