Tailoring the Curing Kinetics of NBR-Based Rubber Compounds for Additive Manufacturing of Rod Seals

Table 3

Effect of the retarding agent CTP on the vulcanization time t₉₀, scorch time t₁₀, and maximum torque in the rheometer at 160°C.

Amount of CTP (phr)	Vulcanization time t90 (s)	Scorch time t10 (s)	Maximum torque S´ (dNm)
0 (Ref. #1, Batch 2)	248	76	29.9
0.5	379	77	27.2
1	384	104	26.5
1.5	500	132	25.1
