Technical Insights & Material Comparison

🔬 Why Choose the Right Rubber Type?

MaterialBest ForKey Advantages
White SiliconeEssential oils, aromatherapy, non-injectable liquidsNon-reactive, odorless, excellent flexibility, ideal for volatile compounds
Butyl RubberGeneral pharmaceuticals, sterile injectablesLow permeability to gases, good elasticity, moderate cost
Chlorobutyl Rubber (CB)Freeze-dried products, high-purity injectablesSuperior chemical resistance, lower extractables, ideal for lyophilization

Observação: Chlorobutyl rubber is particularly recommended for lyophilized (freeze-dried) products due to its excellent moisture barrier properties e low extractables profile, as confirmed by studies in Jornal de Ciências Farmacêuticas e European Journal of Pharmaceutics.
