tesa® 4987
125 µm double sided translucent premium non woven tape
Product Features- High initial tack and peel adhesion
- Excellent temperature resistance
- Very good bonding strength, even to low surface energy materials
Product description
tesa® 4987 is a double-sided non-woven industrial mounting and splicing tape with a highly tackified acrylic adhesive. The premium non-woven tape is, for instance, used for mounting signs and nameplates or other mounting and high-performance lamination applications. tesa® 4987 is especially designed to connect flexible materials to one another. The mounting and splicing tape is able to withstand numerous environmental factors such as humidity, UV light, and temperatures of up to 200°C for limited periods of time. The tackified acrylic adhesive offers excellent hold on various surfaces, very high tack, and good shear strength. The adhesive is coated on a flexible and conformable cellulose non-woven backing that even conforms to difficult 3D shapes.
