Home / About us
Built over five years.
Operating today.
Belcor® is the result of a deliberate R&D journey — from EU-funded projects and new product milestones to solutions already working in the field.
Belcor® — The engineered solution for high-voltage batteries
Belcor® is a specialist initiative born from years of R&D in SiO₂ fiber transformation. We bring together the material science expertise of Belchem and the industrial capacity of Orkli to offer something most companies cannot: fully engineered, customised thermal and electrical protection solutions for demanding battery applications.
What sets belcor® apart is not just the materials — it is the accumulated knowledge to develop personalised solutions for each client’s specific needs. From material selection to validated multilayer assembly, we manage the full development cycle.
Our solutions are not concepts — they are operating in client battery systems today, the result of real EU-funded R&D projects, over five years of development, and ongoing technical collaboration with the most demanding players in the sector.
Five years of deliberate development
What our credibility is built on
Not just who we are — but what we’ve done and what’s working today.
Our Partners
Belcor® is built on the combined strengths of two established industrial companies. Each brings a distinct and essential capability to the partnership.
Orkli S.Coop. — Industrial capacity
Over 60 years as a multi-technology industrial company within Mondragón Corporation. Leaders in safety products for gas, combustion and solar energy applications. The industrial expertise to do things right — and at scale.
Headquartered in Ordizia (Basque Country, Spain), with presence in Brazil, China and Italy. Over a decade of R&D in the transformation of ceramic and silica fibers for high-temperature applications.
Belchem GmbH — Fiber science
Belchem produces BELCOTEX® in Freiburg (Germany) — the ultra-pure SiO₂ fiber that forms the basis of belcor® SIL solutions. Non-toxic, non-mutagenic, bio-soluble, and produced entirely in Europe.
Belchem's scientific expertise in silica fibers, combined with Orkli's industrial capability, is what makes belcor's differential solutions technically possible.
Production & Global Presence
The following locations reflect the combined industrial footprint of our partners — Orkli and Belchem. These are their production and R&D sites. belcor® leverages this global capacity to serve clients without the overhead of multiple dedicated facilities.
Let's work together.
Whether you’re designing a new battery pack or optimising an existing one, we’re ready to help.
