3. 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 2200.
Press cures equated to tc 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.
