Filler

Micro-Poly solid glass beads are hard, resistant (high crush strength), inert, spherical and have excellent chemical and heat resistance properties.

050-20

The ultrafine glass beads with a smooth and polished surface, are crush resistant and fully transparent. It has the texture and appearance of white powder.

Pana Glass Beads Co.’s Micro-Poly 050-20 glass beads can be supplied with coupling agent in order to enhance the dispersion and integration of the glass beads into the polymeric resins.

050-40

The Micro-Poly 050-40 are, ultrafine glass beads with a smooth and polished surface, are crush resistant and fully transparent. The average diameter of the particle size is 40 µm. It has the texture and appearance of white powder.

Pana Glass Beads Co.’s Micro-Poly 050-40 glass beads can be supplied with coupling agent in order to enhance the dispersion and integration of the glass beads into the polymeric resins.
