Borosilicate glass balls are widely used in valve, chemical, laboratory and flow-control applications requiring stable thermal performance, smooth surfaces and non-metallic ball solutions.
Also commonly referred to as borosilicate glass spheres or chemical-resistant glass balls for many industrial environments.
Borosilicate glass balls are commonly used in valve balls, laboratory balls and chemical-resistant ball applications.
Borosilicate glass balls provide stable chemical performance and improved thermal resistance for valve, flow-control and laboratory applications.
Compared with soda lime glass balls, borosilicate balls provide better thermal stability and chemical resistance, making them suitable for many chemical systems and specialized industrial applications.
Borosilicate glass balls are also non-magnetic and electrically insulating, which makes borosilicate balls suitable for applications requiring non-metallic rolling or sealing components.
Due to the brittle nature of glass materials, borosilicate glass balls are generally not recommended for high-impact or high-load rolling applications.
Borosilicate balls are commonly selected where chemical stability and thermal performance are more important than mechanical load capacity.
