  • Patent number: 12252639
    Abstract: The present invention provides a UV-crosslinked hot-melt pressure-sensitive adhesive used for a polyvinyl chloride (PVC) insulation adhesive tape, made by mixing a polymer of vinyl monomers, functional monomers, special soft monomers, and photoinitiators with a tackifying resin and an antioxidant in certain proportions; the composition of the photoinitiator polymer contains a copolymer of one or more polymerizable photosensitive initiators and acrylate monomers, or a mixture of oligomers of one or more polymerizable photosensitive initiators and acrylate high polymers.

  • Publication number: 20220186084
    Abstract: The present invention relates to a method for manufacturing a high temperature-resistant polyvinyl chloride adhesive tape, and more particularly to a method and a production process for manufacturing a high temperature-resistant adhesive tape by applying a UV-crosslinkable hot-melt pressure-sensitive adhesive to a high temperature-resistant polyvinyl chloride film. The high temperature-resistant polyvinyl chloride film is a high temperature-resistant material containing a liquid polymeric plasticizer, a solid polymeric plasticizer, and a heat stabilizer. The hot-melt pressure-sensitive adhesive can be directly coated onto the high temperature-resistant polyvinyl chloride film at 130-150° C.; and then crosslinked and cured by UV irradiation, to make a high temperature-resistant polyvinyl chloride adhesive tape.
