Glass Fiber From an Office Partition Under the Microscope

Glass Fiber from the Padding of an Office Partition

This is a glass fiber from the padding of an office partition. The core panel has a high resin content and the resin often has a high mineral filler content. The padding is a loose glass fiber blanket with little resin. The pad breaths under the cloth coating of the partition so it tends to collect small particles than can pass through the cloth filter.

Transmitted Off Crossed Circular Polarized Light Illumination


A common structure for a cubicle divider consists of a metal frame supporting a resin stiffened glass fiber panel. The glass fiber panel is then covered with a thin loose glass fiber blanket and an outer layer of cloth. Glass fiber from the cubicle divider is heavily coated with heavily filled yellow or orange phenolic resin. The deterioration of the glass fiber panel is typically due to the panel's use as a pincushion or to other forms of mechanical damage.
