tesa® 4970

225µm double sided white PVC film tape.

Product Description:

tesa® 4970 is a white, double-sided mounting tape with a highly tackified acrylic adhesive and PVC backing. The double-sided PVC film tape has exceptional bonding performance and is used in various different industries, frequently used for fastening heavy signs and point-of-sale displays. The tackified acrylic adhesive features excellent adhesive performance, offering a reliable bond, often also on low energy surfaces and rough or slightly dirty substrates. The strong adhesive and PVC backing make the tape highly resistant to numerous factors, including plasticizers, humidity, aging, UV light, and chemicals. tesa® 4970 offers a very high initial bond immediately after application and is ideal for various long-term mounting applications.
