Suitable for thick molded articles. It does not affect cure and initial vulcanizate properties. It also works as a co-agent for peroxide crosslinking with best balance. It exhibits long scorch safety, short vulcanization time, long processing safety and fast cure in combination with high elongation at break and tensile strength. Perkalink® 900 should be added together with accelerators. The recommended dosage level is 0.5-2 phr. It has a shelf life of 730 days.
