Glass Beads of size 710 microns and below are being used as a reinforcement filler in the plastic industry. Depending on he job, bigger sizes are also being used. Spherical shape gives better stress patterns than the irregular shaped particles conventionally used. Glass beads are easily and uniformly dispersed throughout the plastic compound and produce smooth flowing compound which distributes itself evenly, so that all parts of any shaped moulding can be reinforced. Reinforcement with Glass beads will improve the tensile strength, reduce elongation, increase flexural modulus and in some plastics, triple the compressive strength of the finished product.

Given below are few examples of Glass beads being used in plastics :

In adhesives to increase the bond strength.
In fiberglass-epoxy laminates for improved flexural strength.
In moulded phenolic motor housings for good insulation.

In polyesters, using silver coated beads for moulding electrical conductors.

Hollow microsphere are light are light gray or off-white, light, inert and nonmetallic hollow ceramic spheres in the range from 10µm to 850µm.With N2 or CO2 inside and over 95% spheres, the material has excellent fluidity as well as sound electric and heat insulation, Hence it is called” The Space Era Material”. The hollow micro-spheres can be further divided into two kinds: Thin Wall Hollow Ceramic Micro-sphere and Thick Wall Hollow Ceramic Micro-sphere.

Hollow Microsphere (Hollow Glass Microsphere) is small hollow round ball form powder. Grain size is between 1-500 microns, the density is in the 0.1-0.3 g/cm3.Having light weight and big volume, low transmit heat coefficient , high anti- press strength ,and having good dispersion, mobility, the stability. Moreover also having good insulativity, self-lubricating, soundproof, don’t absorb water, fire-proof, corrosion resistance, radiation protection, non-toxicity,etc. excellent function. This product could direct fill in many resin product of thermoset, thermoplastic. It could reduce product’s weight, cut down producing cost, eliminate product’s internal stress,etc. And also could substitute some of bronze powder, molybdenum disulfide and White Carbon etc. some expensively fill material.

Hollow Glass Microsphere is component of inorganic material. The chemistry composition include:SiO2, Al2O3, ZrO.2., MgO, Na2Si2O5 etc. Its grain size from 10 to 500 microns, wall thickness only have a few micron.

Precise glass beads are suitable for bearing-balls and ball-valves of sprayers in cosmetics and pharmaceutical sectors due to its nontoxic,antiseptic and economic merits.

Product Specifications / Features

The high-performance hollow glass microspheres, a kind of ultra-light inorganic non-metallic powder with hollow “ball-bearing” shapes, have been developed into a new type of high performance lightweight material and have been widely applied in recent years. It will be the main direction for new-type compound materials in the 21st century. Its true density is 0.15-0.60 g/cm3; particle size is 5-180μm; Due to its excellent advantages of light weight, bulk density, lower thermal conductivity, higher compressive strength, improved dispersion and liquidity, and excellent chemical stability, it can be used as filler in painting, rubber, plastics, glass steel, man-made stone, putty, exploitation of oil and gas and other materials.
The high-performance hollow glass microspheres are alternatives to conventional fillers and additives such as silicas, calcium carbonate, talc, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties.
The unique spherical shape of hollow glass microspheres offers a number of important benefits, including: higher filler loading, lower viscosity/improved flow and reduced shrinkage and warpage. It also helps the hollow glass microspheres blend readily into compounds and makes them adaptable to a variety of production processes including spraying, casting and molding.
The chemically stable soda-lime-borosilicate glass composition of hollow glass microspheres provides excellent water resistance to create more stable emulsions. They are also non-combustible and nonporous, so they do not absorb resin. And, their low alkalinity gives hollow glass microspheres compatibility with most resins, stable viscosity and long shelf life.

These glass beads are the substitute of sand or rice in Incense Burner.
The incense can be easily put in Incense Glass Beads. Also the beads are unbreakable and used permanently because they don’t absorb moisture like rice and sand.
The best benefit of Incense Glass Beads is that they are helpful for health because they emit the ultrared rays at a certain temperature degree.
The use of Incense Glass Beads can also be made for crystal vases with artificial flowers in a Buddhist Sanctum. Incense Glass Beads make Sanctum more elegant and dignified.

Weight reduction filler Hollow Glass Microspheres   is a tiny sphere with high ball-type rate. Its ball-bearing effect can improve its mobility and reduce the viscosity and internal stress of resin mixture. Therefore, during processing, less heat is produced in composite materials so as to prevent inadequate lubrication and partial thermal decomposition. It is more likely to extrude when molding, which can not only reduce defects in products, but also improve the production efficiency by 15% -20%.
