Crystar Filtration

History and Expertise with Cutting Edge Ceramic Materials

Saint-Gobain Ceramic Materials is an institution in the field of advanced engineered materials, providing unmatched expertise when it comes to ceramics technology.  More specifically, Saint-Gobain Performance Ceramics & Refractories have been providing unique and high added value silicon carbide-based solutions for decades, including the first-to-market recrystallized silicon carbide (R-SiC) product. This outstanding ceramic forms the basis of our Crystar® filtration technology.

Crystar® FT is designed for liquid and air purity, security, and sustainability. The demands of filtration have changed dramatically over the years, as a growing global population forces industries to adopt more demanding processing capabilities to satisfy the needs of global sustainability efforts.

We are Connected to Global Consciousness

Water, the World's Most Valuable Resource

We all need water to survive. It is fundamental to our diet and a key component in industrial processes worldwide. Saint-Gobain is committed to reducing its own water usage and to improving technologies to provide better water usage for a more sustainable future.


Growth of the Global Population


According to current estimates, half of the world’s population will suffer from water shortages by 2050. Reducing the amount of water that we waste and improving recovery and recycling methods is critical for ensuring water security and quality for the next generation and beyond.


Food Scarcity and Security


With an ever-growing and more demanding global population, it is essential that food and beverage products are safe to consume, have long shelf life stability and yields the expected nutritional benefits to humans. Our Crystar® membranes offer a consistent solution for F&B processing to meet these needs.


Long Term Sustainability of the Planet Matters to Us

The sustainability of our planet is a shared issue. It is not one person or industry’s responsibility. Climate change and a rapidly growing global population has heightened the demands on our limited water and food supplies, with concerning forecasts regarding the long-term sustainability of the world as we know it.

At Saint-Gobain, we are prepared to shoulder our share of the burden. We believe that Crystar® filtration technology represents one of the best opportunities for providing secure and sustainable solutions, by improving the way we use our most valuable resources in every aspect of life.
