Who we are

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.

Who is behind belcor®

Our Partners

Belcor® is built on the combined strengths of two established industrial companies. Each brings a distinct and essential capability to the partnership.

Industrial partners
Orkli

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

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.
