Composition characteristics of hollow glass beads:
component
Alkali lime silicate
Pure white
It can be widely used in any product which has the requirement of appearance color.
Light specific gravity and large volume
The density of hollow glass beads is about one-tenth of that of traditional fillers. After filling, the base weight of products can be greatly reduced, more resin for production can be replaced and saved, and the cost of products can be reduced.
Organically modified (oily) surfaces
Hollow glass beads are easy to wet and disperse, and can be filled in most thermosetting thermoplastic resins, such as polyester, epoxy resin, polyurethane, etc.
High dispersion and good liquidity
Because hollow glass beads are tiny spheres, they have better fluidity in liquid resin than fillers of flake, needle or irregular shape, so they have excellent filling performance. More importantly, this kind of microsphere is isotropic, so it will not produce the disadvantage of inconsistent shrinkage of different parts due to orientation, which ensures that the size of the product is stable and does not warp.
Insulation, sound insulation, insulation, low water absorption
The interior of hollow glass beads is a thin gas, so it has the characteristics of sound insulation and heat insulation. It is an excellent filler for various insulation and sound insulation products. The thermal insulation properties of hollow glass beads can also be used to protect the product from thermal shock caused by alternating heat and quench conditions. With high specific resistance and low water absorption, it can be widely used in the processing and production of cable insulation materials.
Low oil absorption rate
The sphere particles determine its minimum specific surface area and low oil absorption rate. The amount of resin can be greatly reduced in the process of use, and the viscosity will not increase much even under the premise of high addition amount, which greatly improves the production operation conditions and increases the production efficiency by 10%-20%.
