Improvement of flexibility and elasticity of vulcanized rubber products.
The role of plasticizers is to improve the flexibility and elasticity of vulcanized products. Their impact on processability is usually beneficial, but they are often used to enhance properties such as heat resistance and electrical conductivity in rubber products. Additionally, in high-filled filler formulations, they promote the dispersion of fillers.
