Thermal/Heat insulation paints is a kind of paints which mixed with HGS(hollow glass sphere) and other fillers to achieve the purpose of heat insulation. Hollow Glass Sphere characteristics for heat insulation paints :
a. hollow with thin air inside→ It make HGS lower thermal conductivity（0.0482-0.0910W/m.k).
b. spherical shape→ HGS can reflect infrared rays within 400nm-2500nm.
c. heat radiation function→ HGS can radiate the heat on the surface of the object to the air.
d. lower density→HGS can replace much resins and TiO2 to reduce paints cost.
e. very good fluidity→It makes HGS mixed with various resins well and increase filler rate.

Advantages of low-density drilling fluid prepared with Hollow Glass Sphere :
Hollow Glass Sphere is inorganic nonmetallic oxide and weakly alkaline with very stable property. It can be added into any kind of slurry without occuring any chemical reaction, which can protect the chemical stability of drilling fluid;
Because of low density and high compressive strength, Hollow Glass Sphere is very suitable for preparing low-density drilling fluid. It is widely used in deep oil wells to keep the constant stability of the density of drilling fluid;
Spherical shape, very good fluidity, perfect lubrication function, these characteristics of Hollow Glass Sphere can reduce friction during drilling process, extend the service life of drill pipes and drill bits, and greatly improve drilling effect as well as drilling performance;
The particle size of Hollow Glass Sphere is compatible with the existing drilling systems and don’t need any extra equipment. Meanwhile, Hollow Glass Sphere used in the drilling fluid can be recycled, which reducing the production costs.
Characteristics of cementing slurry prepared with Hollow Glass Sphere :
The low-density and high-strength slurry system mixed with Hollow Glass Sphere is one of the main ways to resolve the low pressure and the loss of cementing slurry which is easy to leak.
With excellent fluidity, it is easy to mix and pump;
Inorganic components, high temperature resistance and high pressure resistance make slurry very stable.
The thickening time can be adjusted according to operation need, which is easy to handle;
water loss controllable and it helps to prevent pollution;
Very low density slurry with high compressive strength. The compressive strength can reach over 15MPa in 24h;
It can improve the quality of cementation and lengthen the life of oil wells.
Hollow glass sphere are a family of high-strength, low-density additives used in a variety of industrial applications. It's perfectly ok for lighter plastic and rubber made products for transportation industry.
Because of their spherical shape, hollow glass sphere behave like tiny ball bearings, causing them to flow within a liquid polymer much better than common mineral fillers.
In addition, the spherical shape improves the dimensional stability of the polymer composite, resulting in less shrinkage and warpage.
Hollow glass sphere are compatible with most thermoplastics, including polypropylene, nylon, ABS and others, which shows good advantages below :
1. reduce specific gravity
2. reduce VOC
3. reduce shrinkage and warping, keep the dimensional ability
4. improve thermal insulation and noise rduction performance
5. improve the rigidity of the material

1. Because of low density, Hollow Glass Sphere/glass bubbles can reduce the weight of adhesive, what’s more, it has high strength, which won’t disturb the tensile strength and elasticity of sealants.
2. Since the main component is soda-lime borosilicate glass, the Chemical properties of glass bubbles is very stable, sealants with glass bubbles inside has excellent ageing resistance.
3. High temperature resistance, the melting point: 650℃.
4. The particle size of glass bubbles is very small(can be customized), so the bonding is very strong.
5. The fluidity of glass bubbles is better than Irregular filler.
6. Hollow Glass Sphere has a relatively small surface area, so it can keep relatively suitable viscosity when using large volume.
Epoxy Tooling Board filled with Hollow Glass Sphere has good performance in producing furniture parts、automotive model、architectural model、decoration、sculpture.
Adding different proportional of Hollow Glass Sphere into the original formula, not only can reduce the usage amount of resins, reducing cost, but also can make ideal product density.
The oil absorption rate of Hollow Glass Sphere is much lower than traditional fillers, such as calcium carbonate, which makes resin form the film effectively and enhance the adhesion.
Compared with traditional mineral additives, Hollow Glass Sphere has better fluidity and dispersity, which assure dimensional stability of product, reducing shrink and warpage and enhance toughness and impact strength.
With an optimal balance of high strength and low density, hollow glass sphere have become an industry-standard additive for syntactic foams used in buoyancy modules, buoys or buoyancy blocks for undersea vehicles. When hollow glass sphere are formulated with resin, the resultant syntactic foam has a high strength-to-density ratio to provide maximum net buoyancy for a given depth rating.
Buoyancy modules for drill risers :
Help prevent the steel casing from collapsing under its own weight at depth
Protect the drill string against ocean currents
Distributed Buoyancy Modules (DBMs) :
Maximum lift at the required ocean depth
Buoyancy blocks for Remote Operated Vehicles (ROVs)
High net buoyancy foams rated to any ocean depth :
Modular Subsea Buoys can be used for mooring offshore vessels, compensating the weight of subsea structures and be included in the installation of subsea equipment.

Expanded perlite and chemical blowing agent are the commonly used density modifier for emulsion explosive. However, since expanded perlite is limited by particle size, strength and oil resistivity, the explosive performance is low and the storage time is short. As for chemical blowing agent, it's not easy to control explosive density, the storage time is short and there is aftereffect.
Since Hollow Glass Sphere has the characters of low density, low thermal conductivity, low oil absorption, particle size and chemical composition controllable, it's perfectly used as explosive sensitizer. Therefore, the above-mentioned shortcomings can be overcame by adding hollow glass sphere into emulsion explosive, which improves the explosive performance significantly and improves storage stability.
ACRYLIC SHEET LIGHT WEIGHT FILLER
Cast acrylic sheet is shaped by thermoforming to make bathroom fixtures and spa units. Because the acrylic is kept thin and has a low modulus, it is common to stiffen the formed parts by spraying or troweling resin and chopped glass fiber on the back.
By adding 3 to 4% of Hollow Microspheres to the spray-resin you receive:
- Reduction of warping caused by the backup
- Improved resistance of the fixtures to impact damage - Improved resistance to thermocycling
- Lighter weight parts at the same stiffness
- Lower cost fixtures
- More rigid parts
