Advantages Of Hydrophobic Glass Beads
- Mar 22, 2017 -

1 insulation Board, glass beads for particle diameter 0.15~1.5mm porous particles, is the filler of choice.

2, has a low bulk density, between the 80-120/cm3. As a polymer filler material, much less than other mineral filling quantity, load weight, polymer volume savings, thus reducing product costs.

3, low prices, based on hydrophobic packing density of the glass beads are small, install CD in the same weight as compared with other filling materials in polymers, to reduce production costs.

5, low thermal conductivity, thermal conductivity in (0.036-0.054w/m.k), water-repellent glass beads can be used for insulation materials and insulation materials.

6, soundproofing, water-repellent glass beads can block and absorb sound, and can be used for insulation materials.

7, acid, hydrophobic glass beads mostly SiO2 and Al2O3, close to neutral in a variety of solvents, acids, alkalis, salts in the stable.

8, electric insulation, water-repellent glass of good electrical insulation, as a filling material can be used for a variety of electrical switching devices and insulating materials.

9, good thermal stability. Thermal stability of more than 1000 degrees Celsius, especially suitable for fire resistance, fire prevention, fire-retardant materials.

10, flame retardant. Glass beads for hydrophobic inorganic metal oxides and less than 1000 degrees Celsius, does not decompose at high temperature, not easily deformed, as a filled polymer materials can improve the flame retardant property of polymer, used in construction and in the paint and coatings industry.

11, low water absorption rate: water-repellent glass beads glass beads reduced water absorption of 60%~80%.

12, low shrinkage. Water-repellent glass beads is now can meet the need of fill materials industry one of the few low shrinkage rate of fill material, when large proportion when it is loaded into the polymer, this issue is particularly important.
