Sunnyjoint KA9188 is suitable for NR, IR, SBR, and BR or their combined use in conventional and semi-effective vulcanization systems for use with sulfur and thiazole or sulfenamide accelerators. The vulcanizates cross-linked KA9188 exhibited good dynamic and static moduli, tensile strength, tear strength, hardness, rebound, compression set, heat generation, and creep in the Goodrich flexion test. In the sulphur vulcanization in which this product is involved, a thermodynamically stable and flexible hybrid cross-linking bond will be formed. The structure is rubber--Sx--(CH2)6--Sx--rubber (X 3).
