Global Presence

With our worldwide export network, we warrant for the delivery of SiLibeads ceramic beads, SiLibeads glass beads, and SiLiglit effect glitter to over 80 countries. Our own sales offices in England and France, as well as subsidiaries in the USA, China and Russia are a vital expression of our constantly growing international engagement and market presence.

As a global player in niche markets for technical glass and ceramic beads as well as effect glitters we are thus meeting one goal above all: to be as close as possible to our customers.


As a family-run medium-sized company with a tradition of more than 160 years, our goal is to leave behind a livable environment for future generations. Sustainability and innovation go hand in hand. Since July 2020, we have been using 100% renewable energy at our sites in Warmensteinach. We’re now incorporating a special waste water centrifuge to treat our process water in order to largely dispense with the use of valuable fresh water in the manufacturing of our products.

We are proud to be making an important contribution to the greater sustainability of our planet’s finite resources. Our products and services are made with future generations in mind and are constantly monitored for further improvements.

Our push for sustainability is also expressed in our management systems according to ISO 50001 for energy (certified since 2017) and ISO 14001 for environment.
