WebTable 2. The cure characteristics are the scorch time, cure time, minimum torque, maximum torque and torque difference. As shown in Table 2, the scorch times of kaolin-filled NR compounds with ALK were lower than that of without ALK (control compound). The higher the ALK loading, the lower were the scorch times. http://pubs.sciepub.com/materials/1/2/1/index.html facebook marketplace crestview florida
