Material properties
Halobutyl rubber: Halobutyl rubber is a type of synthetic rubber that improves its properties by introducing halogen atoms (chlorine or bromine) on the butyl rubber backbone. This material has good air tightness and water vapor barrier while maintaining good elasticity and flexibility.
Chemical stability: Halobutyl rubber is resistant to a wide range of chemicals, including common pharmaceuticals and disinfectants, which makes it ideal for use in medical settings.
Biocompatibility: Halogenated Butyl Rubber Pistons exhibit good biocompatibility when in contact with the human body, reducing reactivity to human tissues.
Design & Manufacturing
Precision design: The design of Halogenated Butyl Rubber Pistons requires precision to ensure a perfect fit and tightness with the syringe jacket.
Manufacturing process: During the manufacturing process, precision tooling and vulcanization processes are required to produce pistons that meet medical standards.
Quality control: During the production process, strict quality control is carried out on the dimensional accuracy, physical properties and chemical composition of the piston.
Fields of application
Prefilled syringes: Halogenated Butyl Rubber Pistons are commonly used in prefilled syringes, which are pre-filled with drugs and ready for use.
Biologics: Halogenated butyl rubber pistons provide good sealing and protection in the packaging of biologics.
Sterile packaging: For medical environments that require aseptic handling, Halogenated Butyl Rubber Pistons are a critical component in ensuring the sterility of syringes.
Performance requirements
Sealing performance: The piston must be able to provide a complete seal against drug leakage or contamination.
Sliding performance: During syringe use, the piston needs to move smoothly to ensure accurate drug delivery.
Durability: Halobutyl rubber pistons should be durable and able to withstand multiple uses without deformation or damage.
Safety & Regulations
Medical standards: The production and use of halobutyl rubber pistons must comply with the relevant medical device standards and regulations.
Biological evaluation: Before use, the piston needs to be biologically evaluated to ensure that it is safe and harmless to the human body.
Epilogue
As a key component of disposable sterile syringes, the quality of halobutyl rubber pistons directly affects the performance of syringes and the quality of pharmaceutical products. With the continuous development of the pharmaceutical industry, the demand for halobutyl rubber pistons will continue to grow, and at the same time, higher requirements are put forward for material innovation and manufacturing processes. In the future, there will be a greater focus on product safety, reliability, and compatibility with drugs to meet changing medical needs.
