Double-sided tape with fabric backing

Description

tesa® 4964: Flexible Fabric Tape with High-Performance Rubber Adhesive

Product Features:

  • Tear-Resistant Fabric Backing:‌ The tape features a flexible fabric backing that is resistant to tearing, ensuring durability and longevity.
  • High-Weight Rubber Adhesive:‌ The adhesive layer has a high coating weight, which is particularly effective for mounting applications on uneven or irregular surfaces.
  • Residue-Free Removal:‌ In most cases, the tape can be removed without leaving any adhesive residue on clean surfaces.
  • Precautions for Plastic Surfaces:‌ Before applying the tape to plasticized surfaces, initial tests should be conducted to ensure compatibility and prevent potential damage.

  

Application Fields:

  • Carpet Laying:‌ Suitable for securing carpets in place, providing a stable and long-lasting bond.
  • Honeycomb Milling:‌ Used in the milling process to hold honeycomb structures together during manufacturing.
  • Laminating Shoe Insoles and Heel Protectors:‌ Ideal for the leather manufacturing industry, where it is used to laminate shoe insoles and heel protectors for added comfort and support.
  • Splicing Fabric Webs:‌ Effective for joining fabric webs during production processes, ensuring a seamless and strong connection.

 

The tesa® 4964 is a versatile tape designed with a tear-resistant fabric backing and a high-performance rubber adhesive system. Its ability to adhere well to irregular surfaces and remove cleanly from most surfaces makes it a reliable choice for a variety of applications, including carpet laying, honeycomb milling, and the lamination of shoe components in the leather industry. However, caution should be exercised when using it on plastic surfaces, as preliminary testing is recommended to avoid any potential issues.
