Feature
+
- Thermal Resistance: Borosilicate glass tubes exhibit exceptional thermal stability, which allows them to endure extreme temperature changes without cracking or breaking.
- Durability: The superior hardness of borosilicate glass contributes to its outstanding durability. These tubes are highly resistant to mechanical stress and impact, ensuring long-lasting performance even with frequent use and cleaning. Their robust construction means they won't easily chip or break, providing reliable use over time.
- Chemical Stability: Borosilicate glass is resistant to chemical corrosion from acids, alkalis, and other substances. This property ensures that the straws do not degrade or leach harmful chemicals into beverages, making them safe for repeated use. The chemical stability of borosilicate glass further enhances its durability and lifespan.
