Category: Borosilicate;
Features: light weight, low thermal conductivity, high strength, good chemical stability, its surface is specially treated with Pro hydrophobicity oil, easily dispersed in the organic material in the system; the proportion of light volume, with organic modification (lipophilic) surface, high dispersion, good flowing, heat insulation, sound insulation, insulation, low water absorption, low oil absorption;
Application:
1. Artificial agate, marble, fiberglass bowling, and other conforming material (lightening the weight of products);
2. High grade thermal insulation coating (enhancement of warm keeping and heat insulation effect);
3. Civil emulsion explosive (sensitizer: it can improve the detonating performance of emulsion explosive and prolong the storage period);
4. Atomic ash (increase volume, improve grinding performance, improve acid and alkali resistance).
