tesa® 4820

PTFE tape with a silicone adhesive



Product description

tesa® 4820 is a premium single sided PTFE tape with silicone adhesive. This product is a self-adhesive and high performance tape for demanding applications, in which high temperature resistance, very good release properties and abrasion resistance is needed.
Features:
  • Excellent release properties due to PTFE surface and its low surface energy
  • Special silicone adhesive with well-balanced properties: Excellent adhesion level, residue free removable, no oozing at the edges
  • Smooth surface with low friction coefficient
  • Enhanced mechanical stability and abrasion resistance
  • Tensilized material for high tensile strength
  • Excellent temperature resistance
  • Superior resistance against chemicals and solvents

Main applications

  • Belt realization to avoid the just extruded PE edges sticking on the cylinders by laminating tesa® 4820 and tesa® 4830 together
  • Cylinder wrapping on the extrusion coating line next to the hole of the caps
  • High temperature, low friction, anti-stick properties for high end requirements
