👉 Gap fluid, also known as gap fillers or placeholders, is a type of liquid used primarily in the manufacturing of rubber products, particularly in vulcanization processes. It is typically a mixture of petroleum-based chemicals or synthetic polymers that fills the gaps between rubber particles during vulcanization, a heat and chemical process that transforms raw rubber into a durable, elastic material. The gap fluid ensures uniform distribution of rubber particles and enhances the mechanical properties of the final product, such as tensile strength and flexibility. After vulcanization, the gap fluid is removed, leaving behind a homogeneous rubber compound with improved performance characteristics.
