Product information

tesa® 4800

Premium PTFE glass cloth tape with a silicone adhesive

Product description

Premium PTFE glass cloth tape with a silicone adhesive. The 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.
  • Excellent release properties due to PTFE surface and its low surface energy
  • High performance silicone adhesive for residue free removability from a range of substrates
  • Smooth surface with low friction coefficient
  • Excellent resistance against chemicals and solvents
  • Excellent mechanical stability and abrasion resistance
  • Very good insulating properties

Main applications

  • Non-stick release surface for easy de-moulding in composite industry
  • Heat sealing e.g. bag sealing
  • Heat resistant electrical insulation
  • Covering of friction areas and hot metal surfaces
  • Apply a low-friction-surface surface to channels for pour goods
  • Belts for applications that require superior release characteristics and thermal stability.
  • High temperature masking applications
