Technical Insights & Material Comparison
🔬 Why Choose the Right Rubber Type?
| المواد | Best For | Key Advantages |
|---|---|---|
| White Silicone | Essential oils, aromatherapy, non-injectable liquids | Non-reactive, odorless, excellent flexibility, ideal for volatile compounds |
| Butyl Rubber | General pharmaceuticals, sterile injectables | Low permeability to gases, good elasticity, moderate cost |
| Chlorobutyl Rubber (CB) | Freeze-dried products, high-purity injectables | Superior chemical resistance, lower extractables, ideal for lyophilization |
Note: Chlorobutyl rubber is particularly recommended for lyophilized (freeze-dried) products due to its excellent moisture barrier properties و low extractables profile, as confirmed by studies in Journal of Pharmaceutical Sciences و European Journal of Pharmaceutics.
