Performance structure and composition of disposable syringes


The disposable syringe is composed of a jacket, a core rod, a rubber stopper, a cone, a handle and a cone. The scope of application of the product is matched with disposable injection needles for subcutaneous, intramuscular, and intravenous injection of liquid medicine, blood draw or medicine dissolution.

Usually polypropylene, that is, PP, usually medical grade, with relevant certifications. But as far as I know, not all hospitals use the strictest medical grade PP raw materials, and syringe manufacturers will also determine the quality of the materials according to the size of the hospital. This material should have

1. Multiple sterilization options (high pressure, hot steam, ethylene oxide, gamma rays, electron beam).

2. Transparency and gloss.

3. Excellent balance of rigidity and impact resistance, lowest distortion.

4. Good low temperature impact resistance.Only in this way can it meet the needs of making materials for disposable syringes.
