  • What is reactive polyurethane adhesive?
  • Reactive polyurethane adhesives form strong bonds with a variety of different substrates. Their reactivity can be adjusted to meet the requirements of individual production processes. Given the wide range of polyol and polyisocyanate chemistries available, reactive polyurethane adhesives can be formulated with a vast array of properties.
  • Why do plasticizers migrate from PVC to adhesives?
  • Plasticizers are often put into materials to make them more flexible or malleable. As an example, PVC is heavily-plasticized to increase its flexibility. So when bonding PVC with adhesives, those plasticizers can migrate from the PVC into the adhesive. Plasticizer migration is more likely to happen in certain circumstances.
  • What is dual cure polyurethane hot melt adhesive?
  • Dual cure polyurethane hot melt adhesive with low melt viscosity and low initial tack, especially for lamination of textile materials. improved crosslinking by dual curing (combining the reaction mechanisms of silane-modified acrylates and isocyanates).
  • What happens if a plasticizer migrates out of a product?
  • A plasticizer’s main purpose is to increase a product’s flexibility. So when the plasticizers migrate out from that product, flexibility can go with it. This then causes embrittlement. In the case of adhesives, this can cause the adhesive to become unfit for use in an application.
  • Does plasticizer migration affect adhesive performance?
  • Plasticizer migration can cause other additives to migrate too. Typical examples of these additives are UV stabilisers or Anti-Oxidants. If plasticizer migration causes these additives to migrate, the overall performance of the adhesive will deteriorate. There are several occasions where plasticizer migration can have aesthetic effects.
  • What are pressure sensitive adhesives used for?
  • They retain their tack even after cooling and are particularly suitable for substrates that are difficult to bond. The pressure-sensitive adhesives are used in transport and shipping packaging, labeling, adhesive tapes, auxiliary assembly adhesives, as well as in the manufacture of mattresses and upholstery.
