PSA smältlim

PSA is an abbreviation for Pressure Sensitive Adhesive, which means that the adhesive will stick if pressure is applied between substrates.

Sticky hot melt

PSA hotmelts are hot melt adhesives that retain their sticky properties even after cooling. Well-known applications are self-adhesive tapes (duct-tape) and self-adhesive labels (stickers).

PSA formulation

Most PSA hotmelts are based on more synthetic rubbers and resins.

PSA hot melt adhesives are known about the high initial tack and long-term adhesion. Hot melts can be formulated with raw materials such as oils, resins, and polymers like

  • styrene butadiene rubbers
  • atactic polypropylene
  • styrenic block copolymers
  • low-density polyethylene
  • butyl rubber
  • polybutenes

Hot melt pressure-sensitive adhesive applications can be made with extremely high and low coat weights, depending on the requirements of the end product.

PSA hot melt applications

Common pressure-sensitive tape applications include:

  • Duct tapes
  • Masking and paper tapes
  • Tapes for hygiene applications
  • Heavy-duty tapes
