Comminuted glass
Comminuted glass fibres or milled fiber, as the name suggests, consist of glass filament fibres that have been comminuted to lengths of 0.2 mm. Ground glass fibres are used to reinforce resins such as polyester, epoxy, vinylester or polyurethane.
After mixing, the ground glass fibres provide increased reinforcement of the resin. Moreover, mixing with resin can easily be used to fill and reinforce sharp edges or corners.
