Microballoons
Microballoons as lightweight filler for epoxy resin and polyester resin
Microballoons for lightweight fillers and molding compounds
Microballoons are fine, lightweight glass microspheres used as fillers for epoxy resin and polyester resin systems. They enable the production of pressure-resistant, easily sandable fillers and molding compounds, and are widely applied in composite manufacturing, boat building, model making, and industrial production. Thanks to their special structure, microballoons contribute to efficient and controlled material processing.
Properties and advantages of microballoons
Microballoons are white, very fine glass microspheres that ensure a uniform consistency within resin systems. Their low density makes them ideal for creating lightweight fillers and pressure-resistant molding compounds. Even when mixed with resins, the mixture remains flowable, facilitating processing. In addition, microballoons are non-combustible, shrinkage-reduced, and can be easily sanded after curing – making them ideal for precise surface finishing and repairs.
Applications of microballoons in resin systems
The use of microballoons is particularly valuable in boat building, mold making, automotive repair, and model construction. They are employed for edge filling, producing lightweight fillers, or creating high-strength molding compounds. Their spherical structure keeps resin mixtures workable and easy to apply. As a result, microballoons make an important contribution to the efficient production and repair of GFRP, CFRP, and composite components.
