Effect of 3-Aminopropyltriethoxysilane (APTS), Aging Process and Ozone Exposure on Mechanical Properties of Vulcanized Natural Rubber
Keywords:
natural rubber, APTS, ozone and agingAbstract
Mechanical properties, heat  and ozone resistances of vulcanized natural rubber thin pale crepee types can be improved by addition of 3-aminopropyltriethoxysilane (APTS). Addition of APTS improves interaction between polymer filler in rubber and  vulcanized. Vulcanized that have been added 2, 6 and 10 phr APTS characterized by Fourier-Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy / Energy Dispersive X-Ray Spectroscopy (SEM-EDS), while mechanical properties were tested by using a Universal Testing Machine. Ozone testing was performed by using Ozone Aging Tester. The results showed that  APTS addition on vulcanized rubber can increase value bound, aging resistance and ozone resistance, and also mechanical properties such as tensile strength, elongation at break and 100% modulus.
