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.
Features:
- 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
Main applications
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
