Good chemical stability: Borosilicate glass has stable chemical properties and is resistant to acid, alkali and water. This makes it difficult for borosilicate glass bottles to react chemically with the contents when storing various chemicals, medicines, foods, etc., which can effectively ensure the quality and purity of the contents and extend their shelf life.
High heat resistance and thermal stability: Borosilicate glass bottles have a high heat resistance temperature and can withstand large temperature changes without breaking. Generally, they can withstand high temperatures above 200°C and even higher temperatures for a short time. At the same time, under rapid cooling and heating conditions, it has a small thermal expansion coefficient and is not easy to break due to sudden temperature changes. This feature makes it suitable for high-temperature sterilization, steaming and other processing processes, and can also be used safely in cold environments.
Excellent mechanical properties: Borosilicate glass has a high hardness, good wear resistance and impact resistance. Compared with ordinary glass, it is less likely to be scratched and broken. It can maintain good integrity during daily use and transportation, reducing the risk of leakage or deterioration of contents due to packaging damage.
High transparency and optical properties: Borosilicate glass bottles have excellent transparency, which can clearly show the appearance and state of the contents, making it easy for users to observe and identify. Its optical properties are good, and the transmittance of light is high, which will not cause optical interference to the contents. This is especially important for the packaging of some light-sensitive substances, such as medicines and cosmetics, which helps to protect the contents from the adverse effects of light.
Environmentally friendly and non-toxic: Borosilicate glass is a non-toxic and harmless material that does not contain heavy metals and chemicals that are harmful to the human body. It meets the safety standards of the food, medicine and other industries and can be safely used to package products that come into direct contact with the human body. Moreover, borosilicate glass bottles can be recycled and reused, which is beneficial to environmental protection and resource conservation.
Good sealing: Borosilicate glass bottles can work well with various bottle caps or sealing devices to form a reliable sealing effect, effectively preventing the leakage and volatilization of the contents, as well as the intrusion of external air, moisture and impurities, to ensure the stable quality of the contents.
