The present invention relates to a sealant composition for a self-sealing pneumatic tire. A sealant composition suitable for forming a sealant layer in a tire comprises 100 phr of an elastomer, comprising at least 60 phr of an isobutylene-based elastomer component and at least 5 phr of a conjugated diene-based elastomer component. The sealant composition further includes at least 5 phr of a particulate filler, at least 0.5 phr of an organic peroxide, and optionally a colorant that provides a non-black color to the sealant.

    本发明涉及用于自密封充气轮胎的密封剂组合物。适用于在轮胎中形成密封剂层的密封剂组合物包含100phr的弹性体,包含至少60phr的基于异丁烯的弹性体组分和至少5phr的基于共轭二烯的弹性体组分。密封剂组合物进一步包含至少5phr的粒状填料、至少0.5phr的有机过氧化物和任选的着色剂,所述着色剂为密封剂提供非黑颜色。
