Leather-Like Material Based on Natural Rubber Composites

In-house leather like material based on filled natural rubber (NR) with various filler types (i.e., clay, SiO2 and CaCO3) was prepared by calendaring method. NR/SiO2 exhibited the highest tensile strength, 100% modulus, elongation at break, and tear strength. The lower wear index and % weight loss in case of NR/SiO2 indicated the best abrasion resistance among the other fillers due to the fine dispersion of SiO2 in the NR matrix. Also, the uniform dispersion of SiO ( )together with high surface area of SiO2 enhanced the interaction with NR matrix led to the higher elasticity of NR/SiO2 vulcanisate. Therefore, NR/SiO2-based leather was prepared and exhibited no significant difference in the abrasion resistance compared to the commercial leather. Furthermore, it was observed that AIR/SiO2-based leather exhibited higher skid resistance than the commercial one. Therefore NR/SiO2-based leather has been proposed to use as commercial artificial leather.

Automated summary

In-house leather-like material based on filled natural rubber (NR) with SiO2 filler exhibited the best abrasion resistance and elasticity compared to commercial leather. Therefore, it is proposed to use NR/SiO2-based leather as a commercial artificial leather.
