Advantage of Tempered Borosilicate 3.3 Round Sight Glass Plate/Sheet/disc
1)The material is dense and does not absorb water.
2)Excellent acid resistance, alkali resistance and water resistance.
3)High hardness, abrasion resistance, dishwasher safe.
4)Does not contain harmful substances to the human body.
5)It is very easy to clean, not easy to stain, and it will be as clean as new after long-term use.
6)When used in a microwave oven, the heating is not hot, absorbs very little microwave, and saves electricity and energy.
7)It has the characteristics of resistance to rapid cooling, rapid heat, impact resistance, and non-fragility.
