Natural rubber was eliminated due to its impure properties, poor chemical resistance and poor sealing properties. Because the oral liquid bottle uses butyl rubber stopper, after the bottle is sterilized at high temperature, the butyl rubber stopper has higher expansion performance than the natural rubber stopper and has a higher rebound property (this is caused by different molecular structures). The characteristics that can improve the quality of drug storage and safety in use are recognized and widely adopted internationally.
