Title:
シーラント材組成物およびそれを用いたタイヤ
Document Type and Number:
Japanese Patent JP7188468
Kind Code:
B2
Abstract:
A sealant composition of the present invention includes a rubber component (A), a tackifier (B), and a plasticizer (C), in which the tackifier (B) has a softening point of 50° C. or higher, the plasticizer (C) has a dynamic viscosity at 40° C. of 2500 mm2/s or less, and a mass ratio of (C)/(B) of the plasticizer (C) to the tackifier (B) is 0.35 or more. Thus, the sealant composition can provide improved sealability, viscosity temperature dependency, and fluidity during storage of a tire.
