tesa 4820 is a premium single-sided PTFE adhesive tape with silicone adhesive for demanding technical applications.
Technical documentation
Description and applications
Production of tapes to prevent the newly extruded edges of the PE attach themselves to the cylinders by laminating together tesa® 4820 and tesa® 4830
Cylinder coating on the extrusion line next to the cork hole
High temperature, low friction and non-stick properties for high level requirements
Key features
- Excellent release properties thanks to the PTFE surface and its low surface energy
- Special silicone adhesive with well-balanced properties: excellent adhesion level, removable without residue, no escape to the edges
- Smooth surface with low friction coefficient
- Greater mechanical stability and abrasion resistance
- Tight material for high tensile strength
- Excellent resistance to high temperatures
- Superior resistance to chemical agents and solvents
