abrasion index and silica content - Nails by Katy

2020-12-8  The increasing in C 1 caused the increases in tensile strength and abrasion index and the decrease in heat build-up. The optimum properties of rubber with silica loading at 30 phr was achieved by adding 2,000 gÂmol-1 HTNR at a loading of 8%w/w of silica content. However, for silica-reinforced NR, TESPT provided better properties than HTNRs.

Optimal Mixing Ratios of Silica and Hybrid Resin with ...

As observed at a mixing ratio of hybrid resin:mixing silica of 1 ∶ 2 (mass ratio), this phenomenon can also be explained by the fact that an increase in the silica content may reduce the cross-linking density because of the aggregation of silica owing to the high specific surface area of silica. Therefore, it was found that the hybrid resin could complement the weakness of the epoxy resin, easy-demonstrating
