AronFibro Rubber Masterbatch
AronFibro MB is a rubber masterbatch which capitalizes on the easy dispersiveness of our CNF. It is possible to achieve both elasticity and breaking strength while maintaining rubber-like properties. It contains 20 phr of CNF. It is also characterized as being easy to handle because it maintains good CNF dispersiveness even with rubber dilution.
Features
- This is a masterbatch of CNF obtained with our unique manufacturing method combined with rubber in a high concentration.
- We make it by mixing and drying the CNF aqueous dispersion and rubber latex (Fig. 1).
- The carboxy group in CNF is the sodium salt form (-COONa).
- It disperses well in rubber. Therefore, it is possible to increase the Young’s modulus while maintaining the inverted-S-shaped stress—strain curve unique to rubber (Fig. 2-1 and 2-2).
- It is possible to raise the abrasion resistance by adding it to rubber (Fig. 3-1 and 3-2).
