- Providing safety in EV -

Safety solutions against critical events in battery systems along with improved (battery) performance and lifespan.

Engineered Cushion pad, Venting pad and Enclosure solutions for high-voltage battery systems – Bespoke recipes and formulations –not off the shelf –for specific requirements & applications.

Why belcor®

Three reasons we stand apart in the battery materials landscape.

01

Differential product technology

Belcor® SOFT, SIL and MP are solutions not many can deliver. For certain safety and performance requirements, they offer a superior alternative to the market’s state of the art.

02

Bespoke, not off-the-shelf solutions

We don’t sell from a catalog. We co-develop the solution with you — rapid prototyping, quick iterations, and a technical conversation – that’s where the real value is created.

03

Credibility & capabilities

EU production, high-quality BELCOTEX® fiber, expert partners in complementary materials, our own pilot line. Solutions operating in client systems today.

Two critical challenges in high-voltage battery systems

The problems our engineered solutions address.

Safety against critical events

Barriers that both stop thermal runaway propagation from cell to cell — surviving extreme temperatures, maintaining integrity under compression, and never emitting toxic gases – and facilitate evacuation of harmful gases, while providing dielectric capabilities.

Up to 1200°CNo off-gassingDielectric strength

Battery performance & lifespan

Precision compression pads that maintain optimal cell contact throughout the lifespan, managing swelling without degrading performance from BOL till EOL.

How we work together

A three-phase customer-oriented process where the technical conversation is where the real value is created.

01

Understand

Output: REQUIREMENTS SPEC LIST + PRELIMINARY SOLUTIO

The heart of this step is to clearly understand customer needs, requirements, and challenges for a specific application that is performed together with the customer. Typical data to be collected: cell-related mechanical constraints (BOL, EOL), operating temperatures, and fire exposure requirements.

02

Design and developKEY VALUE

WHERE BELCOR® DIFFERENTIATES FROM THE COMPETITION

This is where belcor® sets itself apart. We co-engineer the solution through an iterative cycle with physical prototypes — delivered in 2–3 weeks each — that you can test under real conditions in your application. Your feedback shapes the next iteration.

03

Quotation and order

Output: purchase order / contract

Binding quotation is negotiated and closed. Since the solution is technically validated; this step is about formalizing the terms to move to series production.

Our solution portfolio

Four key substrates plus the multilayer assemblies ready the application.

SOFT
EXPERTISE

belcor® SOFT

The basic nonwoven porous ceramic substrate whose main characteristics are a low thermal conductivity and good compression-relaxation behavior.

SIL

EXPERTISE

belcor® SIL

Silica fiber substrate engineered for thermal runaway protection at extreme temperatures.

MP
EXPERTISE

belcor® MP

Microporous substrate delivering exceptional insulation at minimum thickness.

GEL
EXPERTISE

belcor® GEL

Aerogel substrate for applications where the standard is fit for purpose.

Converter
The complete solution

Multilayer Assembly

What we deliver to most clients: substrate + adhesives + protecting films + physical barriers (mica) + liners — the optimized, validated assembly ready to be integrated directly into your application. This is where our converter capability turns substrate expertise into a finished product.
