The veterinary syringe is a new type of packaging container that has both storage and injection functions. It has the characteristics of no cleaning, no disinfection and no filling during use. It is mainly used in dairy cow mastitis, pet nutrition ointment, cockroach medicine and other drugs package of. What material is used for the veterinary syringe with so many advantages, and what are the characteristics?
The veterinary syringe is made of polyethylene material with many advantages. This material is a thermoplastic resin made by polymerization of ethylene. It is non-toxic, tasteless, and has excellent low temperature resistance (the minimum use temperature can reach 100~ -70°C), good chemical stability, resistant to most acids and alkalis (not resistant to acids with oxidizing properties). It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.
Polyethylene can be processed by blow molding, extrusion, injection molding and other methods, and is widely used in the manufacture of films, hollow products, fibers and daily sundries. In actual production, in order to improve the stability of polyethylene to ultraviolet rays and oxidation, and improve processing and use performance, a small amount of plastic additives need to be added. In addition, antioxidants, lubricants, coloring agents, etc. Which are also added to expand the application range of polyethylene.
Most of the medicines contained in syringe are liquid or paste. Polyethylene material is resistant to most acid and alkali corrosion and meets the storage requirements of such medicines. This material has good processing properties, is light in texture, and is easy to transport. In addition to being used as a raw material for the production of veterinary syringe, polyethylene is also widely used in packaging for veterinary vaccine bottles, liquid bottles, disinfectant bottles, etc., and is a good pharmaceutical packaging material.
