Materials
The main materials for syringe rubber stoppers are natural rubber and synthetic rubber. Natural rubber is extracted from rubber trees and has good heat resistance and chemical corrosion resistance; while synthetic rubber is artificially synthesized and generally has better mechanical properties and stability.
Applications
Syringe rubber stoppers are mainly used in the medical device and chemical industries. Their primary function is to seal medications to prevent contamination and leakage. Different applications require different materials for the rubber stoppers.
Colors
Syringe rubber stoppers are typically available in white, gray, red, yellow, blue, and other colors. Different colored stoppers have different characteristics and uses.
1. White rubber stoppers: Commonly used for sealing ordinary pharmaceuticals and chemicals, with good acid and alkali resistance and heat resistance.
2. Gray rubber stoppers: Commonly used for sealing biological products and medical devices, with good high-temperature resistance, acid and alkali resistance, and chemical corrosion resistance.
3. Red rubber stoppers: Commonly used for injectable medications, with good elasticity and sealing performance.
4. Yellow rubber stoppers: Commonly used for sealing chemical reagents and special medicines, offering good acid and alkali resistance and heat resistance.
5. Blue rubber stoppers: Commonly used for sealing special medicines, offering good high-temperature resistance and radiation protection.
In general, different colored rubber stoppers have different material characteristics and uses. Choosing the appropriate rubber stopper can ensure the quality and safety of medicines.
