    Rubber sealing components for aqueous parenteral formulations, powders, and lyophilized powders are typically made from materials obtained by vulcanizing (cross-linking) macromolecular organic substances (elastomers) and adding appropriate additives. Generally, the commonly used butyl rubber stoppers in the market are mainly for 13mm, 20mm, 28mm, 29mm, 32mm, and 34mm injectable glass vials/bottles. The main components are chlorobutyl rubber and bromobutyl rubber along with various additives (such as vulcanizing agents, accelerators, stabilizers, pigments), and the formulation depends on the performance required by the product.
