Butyl Rubber Stopper Benefits and Advantage:-

1. Low permeability to air, gases and moisture
2. Stable chemical and biologically inertness & lower extractable compared to other rubber
3. Heat resistant, ozone resistant and UV resistant
4. Excellent self-seal function when penetrate

Chlorobutyl and bromobutyl rubbers are an excellent choice for pharmaceutical stoppers and seals applications due to low levels of additives and impurities, high impermeability to moisture and air, chemical and biological inertness, resistance to aging and heat sterilization, and easiness to vulcanize using low levels of ‘clean’ curatives.

Formulation of butyl rubber stopper

Formulation comprises more than just the base rubber - it includes fillers, vulcanizing agents, antioxidants, pigments, etc. The sum of these components, and the manner in which compounding is performed, gives the formulation its properties.
