Compounding Report

Recent work on a 39 ACN N-Nanbrol® masterbatch 80, let down to 60 phr nanofill, illustrates the range of results available with little change in compounding.

Nanbrol® is different, but responds similarly to other filled NBR’s.

Three cases are reported here. Case 1 is low cure state, and the cure state is increased through case 3.

N-Nanbrol Modulus Curve

Modulus depends upon cure state. Cure state is increased from case 1 through case 3.

While the 25% modulus is higher, the 50% modulus is more than double the low cure state case.  Tensile values were about the same, but as you can see, the elongation ranged from under 150% to almost 400%.

Nanbrol® masterbatch responds like most white-fill masterbatch, but with improvements in physical properties and much better barrier, heat resistance, and processability.

Nano clay creates a tortuous path in pressed rubber vulcanizate that makes it more difficult for gases to enter and escape the finished item.  The barrier enhancement is well understood from the literature.  Nanbrol® high density nanofill masterbatch can go beyond what academics can achieve in the lab, and that brings prices down.  Call or email us today to request a lab-quantity sample.  Larger volumes are available for quick delivery.
