Quartz, CMC and ceramic continuous filament offerings

As of April 2023, Saint-Gobain Quartz (Saint-Pierre-lès-Nemours, France) evolved into a new business, Saint-Gobain Advanced Ceramic Composites (ACC). The goal of this new name is to reflect the company’s ambitions to diversify its solutions and expertise to grow in high-potential markets. Saint-Gobain ACC is implementing a growth strategy focused on quartz, ceramic continuous filaments and ceramic matrix composites (CMC) activities for aerospace, connectivity and industrial markets.

The company’s historical quartz activities will remain a strong focus in its roadmap. Saint-Gobain ACC says it will continue to invest in the development and production of quartz filaments for radomes, electronics, and electrical and thermal insulation in particular.

Quartzel(R) products include 9- or 14-µm-diameter homogeneous, non-porous, continuous, amorphous, ultra-pure silica glass with a SiO₂ content >99.95%. Quartzel(R) is available in yarns and rovings processed to varying levels of twist and ply ranging from 17-1,600 tex. This includes chopped fibers and nonwoven textile substrates including wool, felts, needle punch felts veils and powders.

Saint-Gobain ACC’s ceramic continuous filaments activity focuses on a portfolio of solutions based on continuous filaments made of alumina and mullite, dedicated to extreme temperature applications. These filaments are used, for instance, in composites designed to lighten aircraft structures while improving engine efficiency, therefore contributing to a reduced CO₂ footprint.

In addition to its historical facilities in Nemours, France, and Louisville, Kentucky, Saint-Gobain ACC welcomes Courtenay, France, into its industrial network for the upcoming production of ceramic continuous filaments.
