  • Patent number: 11932784
    Abstract: The present invention provides an adhesive composition for a dicing tape, which may prevent the success rate of chip pick-up from decreasing due to an oxygen inhibition phenomenon occurring in a dicing process, and a dicing tape including the same. The adhesive composition for a dicing tape includes an adhesive binder, a singlet oxygen scavenger, a photosensitizer, and a photoinitiator.
    Type: Grant

  • Patent number: 11639565
    Abstract: Disclosed are a high-performance hybrid tire cord capable of realizing high performance and lightweight of a tire, and a method for manufacturing same. The hybrid tire cord of the present invention comprises a PET primarily-twisted yarn, an aramid primarily-twisted yarn, and an adhesive coated on the PET primarily-twisted yarn and the aramid primarily-twisted yarn. In the hybrid tire cord having a predetermined length, the length of the aramid primarily-twisted yarn is 1 to 1.1 times the length of the PET primarily-twisted yarn, after the secondary twist is untwisted.

  • Publication number: 20190226750
    Abstract: A refrigerator planar heating element is arranged inside a refrigerator to radiate heat. The refrigerator planar heating element includes a defrosting planar heating element including a first substrate having one surface on which a first pattern for radiating heat is printed with conductive ink, a second substrate having one surface on which a second pattern for radiating heat and having the same form as the pattern of the first substrate is printed with conductive ink, and an adhesive layer performing bonding such that the patterns of the first substrate and the second substrate are overlapped in a vertical direction. The invention has heating performance more excellent than that of conventional heating elements, and applies an inverse current patterning technique so as to make a current flow in opposite directions at both surfaces of a substrate, thereby effectively shielding electromagnetic waves.
