Borosilicate Glass Balls

Color: Clear
Max. Temperature: 400° F
Fabrication: Annealed

Also called Pyrex and Schott glass, this glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.

Resin Fillers

Add these hollow microspheres to epoxy, urethane, or polyester resins to reduce weight and shrinkage.

Glass microspheres are a good choice when water resistance or sanding is required.
