What is vulcanization in rubber?

Vulcanization is a chemical reaction process that forms rubber products . The vulcanizing agent serves to link polymer chains through cross-linking reactions. ZnO and SA in rubber compounds are used in various ratios, according to the rubber product produced .

Does arachidic acid reactivity affect vulcanization of isoprene rubber?

However, the reactivity of arachidic acid with ZnO was found to be low, which prolonged the induction period and curing time, and slowed down the curing rate in the vulcanization of isoprene rubber. These results help to understand the complicated vulcanization reaction of rubber, especially

Can zinc stearate improve vulcanized rubber?

In vulcanization, the materials commonly used as activators and coactivators are ZnO and stearic acid, respectively. In this research, ZnO and stearic acid were replaced with zinc stearate to improve the characteristics of vulcanized rubber. Zinc stearate was applied in four formulas with a composition of 5 to 9 phr.

Can ZS improve the homogeneous distribution of vulcanized rubber?

In addition, the vulcanized rubber mechanical properties test results for the compression set parameter increased between 28.6% and 57.1%. Scan results with SEM–EDS showed that using ZS could improve the homogeneous distribution of the material in the vulcanized matrix of solid tire rubber. 1. Introduction

Can ZS vulcanize rubber compound?

Using ZS in the vulcanization process of rubber compound into rubber vulcanizate from the test data accelerated the drying time (t 90) between 58.3% and 69%. The scorch time test (ts 2) results for the VBP-01 formula were longer than the rubber compound using ZS.

What is natural rubber vulcanizate?

Natural rubber is a polymer that can withstand loads and return to its original state after receiving loads [54, 55]. The molecular structure and bonds between the materials formed influenced compression set rubber vulcanizate.
