Comparison of NIPOL ® IR and Natsyn ® Polyisoprene
NIPOL ® IR vs. Natsyn ® in a Furnace Black Loaded Compound Three NIPOL IR polymers of different viscosities were compared to Natsyn 2200 in a carbon black-loaded compound. The viscosities of the NIPOL IR polymers were slightly higher, while scorch and cure times for the NIPOL IR compounds were markedly slower, than those of Natsyn Press cures equated to t c 90 indicate that NIPOL IR 2200 has higher modulus and tensile strength. All three NIPOL IR polymers exhibited improved tear strength, compression set resistance and resistance to flex-crack growth.
