BJO-0930 Microballoon Filler | Lightweight Phenolic Microspheres for Composites

BJO-0930 Microballoon Filler is a phenolic-based, reddish-brown hollow microsphere material developed for use in resin and composite systems where controlled density and consistent performance are required. It is commonly incorporated into epoxy, polyester, and other thermoset resins to modify material behavior and improve processing characteristics.

When blended into resin systems, BJO-0930 produces a lightweight and uniform mixture that enhances handling, promotes even dispersion, and maintains surface integrity during application. Its controlled particle structure supports stable viscosity, predictable flow behavior, and reliable finishing results in both manufacturing and repair environments.

This material is widely used across aerospace, marine, automotive, and industrial composite applications where dimensional stability, repeatability, and process reliability are essential. It supports efficient fabrication workflows and is suitable for precision filling, fairing, and surface preparation tasks.

BJO-0930 is manufactured as a phenolic hollow microsphere with a nominal particle size classification commonly referenced as Phenolic 135 Micron, making it suitable for applications requiring consistent particle distribution and controlled material performance.
