tesa 4820 PTFE film tape

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
