The production of medical rubber stoppers for blood collection tubes is a precise and quality-controlled process. Here are some key steps involved:

Raw Material Selection: High-quality medical-grade elastomers, such as butyl rubber or bromobutyl rubber, are chosen for their excellent sealing properties and compatibility with blood samples.

Formulation and Compounding: The selected rubber material is mixed with various additives and curing agents to achieve the desired characteristics, such as elasticity, chemical resistance, and biocompatibility.

Molding and Shaping: The rubber compound is shaped into the specific design of the stopper, ensuring it fits the blood collection tube securely. These molded stoppers often have features like wings or flanges for easy manipulation by healthcare professionals.
