💡

Product Application

The adaptability of high borosilicate glass allows it to provide specialized solutions for multiple industries:

1. Daily Usage: High borosilicate glass is considered the healthiest and safest daily usage glass. It contains no harmful substances, features excellent anti-temperature difference properties, a non-bursting rate, and superior gloss.

2. Laboratory Use: Highly resistant to thermal shock and heat. It is remarkably resistant to water, strong acids, alkalis, and saline solutions.

3. Lighting Industry: High optical and cosmetic quality with no extra reflection or refraction. Tight geometric tolerances allow for stable manufacturing and easy assembly. Low thermal expansion and chemical resistance make it suitable for adverse conditions.

✅

Product Advantages

Our High borosilicate glass tubes feature low expansion rates, high temperature resistance, high strength, high hardness, high light transmittance, and exceptional chemical stability. The premium quality has earned unanimous favorable feedback from global clients.
