Factorial design investigation on two-way quaternary factors of thermal aging of chlorinated nitrile latex tensile properties
This study aims at investigating the quaternary factors, namely zinc di-N-butyl dithiocarbonmate (ZDBC), sulfur, zinc oxide (ZnO), and potassium hydroxide (KOH) on the tensile strength and elongation of chlorinated nitrile latex film.

| Summary: | This study aims at investigating the quaternary factors, namely zinc di-N-butyl dithiocarbonmate (ZDBC), sulfur, zinc oxide (ZnO), and potassium hydroxide (KOH) on the tensile strength and elongation of chlorinated nitrile latex film. Full factorial design analysis was employed to examine the factors and their combination two-way interactions with the tensile properties. The factors' effect on the variability or the stability of the resulting latex films were analyzed as well. The results showed that KOH, which was used to adjust the pH of the latex system greatly affected the tensile strength of the latex film, whereas sulfur has minor influence on tensile strength. Meanwhile, KOH also interacted in combination with ZnO and sulfur to affect the elongation of the latex films. Addition of KOH changed the pH by affecting the electronic repulsion and gelling stability of the latex matrix. Consequently, the variability in tensile strength and elongation of latex film were according to the amount of KOH. Finally, the simple mathematical models with a regression range 0.73-0.86 were developed to relate the factors and the tensile properties of the latex. |
