Hollow
glass beads , are made of an inorganic material. Chemical composition o : silica, alumina ,
zirconia , magnesium oxide, sodium silicate . Ten to several hundred microns
particle size , is filled with CO2 gas inside a closed micro- sphere. And has a
light weight , low thermal conductivity , non-toxic , non-flammable , chemical
stability, high dispersion , etc. . Is artificial marble , glass, steel , putty
, paint , plastic, fragments medicine , chemical industry, building materials
industry, excellent products fillers
Hollow glass beads in the resin characteristics
:
1, good color . Appearance and calcium carbonate as pure white , any color can be widely used in products .
2, light weight bulky . After filling the application can greatly reduce the weight of products , thereby reducing the amount of resin main raw material , reduce product cost .
3, the filling process is simple . Hollow glass microspheres without surface treatment , can be directly mixed with the main raw materials or finished masterbatch . Fill hollow glass beads fill product than other fillers products lighter, bigger, and better indicators of various physical and mechanical properties

4, can improve the physical and mechanical
properties of plastic products . Hollow glass beads filled plastic allows the
hardness and elastic modulus of the large increase , stiffness and stress
damping capacity also increased. But the impact performance. However, the
impact resistance down the number but also with the surface of hollow glass
microsphere treatment related, such as choosing the right coupling pretreatment
reduces impact on the material properties.
5 , low oil absorption . Compared with the conventional
calcium carbonate filler material , hollow glass beads amount much lower
absorption rate , different models of oil per 100g rate between 7 to 50 mg ,
and calcium carbonate per 100 grams of oil absorption up to 120 ~ 130 mg, heavy
calcium carbonate as high as 50 to 60 mg. This low absorption rate of the
filler material in the production process not only reduces the amount of
plasticizer , but also increases the filling quantity disguise the overall cost
reduction.
