3. Mechanism of Action of BDMAEE in Elastomer Formulations
The primary function of BDMAEE in elastomer formulations is to catalyze the cross-linking reactions between polymer chains, leading to the formation of a three-dimensional network structure. This process, known as vulcanization, is essential for improving the mechanical properties of elastomers, such as tensile strength, elongation, and tear resistance.
3.1 Cross-Linking Reactions
BDMAEE works by accelerating the decomposition of peroxides or sulfur compounds, which are commonly used as curing agents in elastomer formulations. The mechanism involves the following steps:
- Initiation: BDMAEE reacts with the curing agent to form reactive intermediates, such as free radicals or thiyl radicals.
- Propagation: These intermediates attack the double bonds in the elastomer chains, leading to the formation of new cross-links.
- Termination: The cross-linking process continues until a stable network structure is formed, resulting in improved material properties.
3.2 Influence on Processing Parameters
In addition to enhancing the mechanical properties of elastomers, BDMAEE also improves the processing efficiency of elastomer formulations. By accelerating the cross-linking reactions, BDMAEE reduces the curing time and temperature required for vulcanization. This leads to faster production cycles, lower energy consumption, and reduced manufacturing costs.
