Saturator Belts for Fiberglass Mat Impregnation and Binder Application

In fiberglass mat production, the choice of the right process belt—especially in the saturator section—is critical to achieving consistent product quality. These saturator belts play a key role in the impregnation process, where glass fibers are saturated with a binder to meet the specific requirements of various industries, including roofing, flooring, and other technical applications.

Glass fibers vary significantly in length and thickness depending on the desired product properties. To ensure optimal performance, the mesh size and open area of the belt must be carefully selected. This helps prevent fiber entanglement and fiber loss, while also supporting efficient binder dewatering, even when dealing with binders of varying viscosities.

GKD offers a wide range of process belts for fiberglass mat production, tailored to the specific fiber and binder characteristics of each application. The right belt specification—whether referred to as a saturator belt, impregnation belt, or binder application belt—has a direct impact on the smoothness and efficiency of the production process.

Key factors such as the number of contact points per unit area, the web structure, and the belt’s lateral stability influence the structure and quality of the final fiberglass mat. As binder formulations become increasingly diverse and complex, selecting the right belt becomes even more critical. For example, high-viscosity binders can reduce dewatering performance, making the belt’s drainage capability a decisive factor.

To meet these challenges, GKD’s fiberglass impregnation belts are manufactured with a non-marking endless woven seam, ideal for cantilever installation. These belts are designed to deliver excellent running properties and long service life under demanding conditions.
