Name: tesa® 4580
Brand: tesa®

Highly Permeable Venting tape

Product description

tesa ^® 4580 is a single-sided tape for venting applications. It is based on a porous nonwoven fabric coated a selected pattern of adhesive dots. The selected design ensures an outstanding air permeability. It is an ideal solution to increase efficiency in your foaming processes.

Features:

The high air permeability allows the foam to expand fast for efficient foaming process
The permeability for air and other gases is homogeneously spread to ensure constant foaming results
Works 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
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
