  • Publication number: 20180086945
    Abstract: Provided is a polyvinyl chloride (PVC) adhesive tape less susceptible to cracking at low temperatures even with thin PVC film. The pressure-sensitive adhesive (PSA) tape provided by the present invention comprises a PVC film and a PSA layer placed on at least one face of the PVC film. The PSA tape shows a tensile elongation at break of 80% or higher at ?20° C.

  • Patent number: 8298660
    Abstract: The present invention provides a flame-retardant polyolefin resin composition having superior molding processability, a resistance to thermal deformation and suitable stretchability and intensity, which is rich in elastic deformation. The present invention provides a flame-retardant polyolefin resin composition comprising component A (a thermoplastic resin having a carbonyl oxygen atom in the molecular skeleton), component B (a polymer alloy containing an ethylene component and a propylene component), component C: a modified polyolefin polymer containing an acidic functional group and having a weight average molecular weight of 10,000-80,000 and component D (an inorganic metal compound), and substantially free of a halogen atom.
