Research progress on eco-friendly rubber release agents

Rubber tends to adhere to molds during production due to its high viscosity at elevated temperatures, affecting product quality. The use of release agents facilitates the removal of rubber from molds, enhancing production efficiency and extending mold lifespan. With increasing emphasis on environmental protection, development and selection of high-performance, eco-friendly release agents have become pressing issues. This paper reviews recent advancements in rubber release agents, highlighting common features and selecting suitable surfactants for water-based, eco-friendly release agents. The study presents our recent progress in rubber release agents, comparing different surfactants used to formulate release agents. Particle size tests, emulsion stability tests, and release effect tests during tire production demonstrated promising results.
