Technologies

Innovative, high-performance fabrics at the heart of every Ypiresia product.

Materials and processes

3K carbon fibre

High strength, minimal weight, T700-grade performance. For demanding applications: aviation, automotive lightweighting, sports equipment and drones (UAV).

Silicone-coated fabric

Glass-fibre base coated with silicone on one or both sides. The coating provides water tightness, resistance to spatter and abrasion, flexibility when folded and good temperature stability. Covers, heat shields and equipment protection.

High-strength glass fibre

High-density weave for severe thermal and mechanical loads. Resistance to flame and chemicals, dimensional stability, abrasion resistance. The basis of our fire blankets and industrial protection.

Our technical fabrics

All our products are built on a selection of high-temperature fabrics that we test and assemble ourselves. Eleven references are available as samples, from 3K carbon through to lightweight glass fibre, depending on the thermal resistance, flexibility and mechanical strength required. They are listed below from the highest performing to the lightest, with the reference numbers marked on the physical samples.

Coming soon: a video of the blowtorch resistance test will be published for each sample, so you can see how the fabric actually behaves under direct flame.

Fire testing and classification. Our fabrics, apart from 3K carbon fibre, are assessed to EN 13501-1:2018, fire classification of construction products and building elements, part 1: classification using data from reaction to fire tests. Two test methods are applied: EN 13823:2020+A1:2022, reaction to fire tests for building products excluding floorings exposed to thermal attack by a single burning item, and EN ISO 1716:2010, determination of the gross heat of combustion.

Blowtorch test: our protocol

At Ypiresia Swiss Fire Protection we apply a fixed protocol, based on aviation test methods (ISO 2685) and on thermal barrier testing for batteries (UL 2596). Every result is therefore measurable and repeatable.

Preparation

We test at least three samples of 300 × 300 mm. They are conditioned for 24 hours at 23 °C and 50 % relative humidity, then clamped to a frame. The flame hits the centre of the sample, perpendicular to its surface.

Heat source

We use a professional propane burner fed from a cylinder, with an adjustable regulator, to keep the flow constant throughout the test. The distance between nozzle and fabric is set between 50 and 100 mm. Before each series, the temperature at the point of impact is checked: the target is between 1000 and 1100 °C.

Test sequence and measurements

Parameter	Value
Exposure steps	5 minutes and 15 minutes
Temperature readings	At 1, 5 and 15 minutes
Documentation	Video

Assessment criteria

For each sample we record:

any burn-through, and the time at which it occurs
afterburning
smoke emission
shrinkage
mass loss

Every test is documented in a dated and signed report.

Custom design and prototyping

Beyond our catalogue, we design and build custom products from these fabrics. You give us your constraint, thermal, dimensional or operational, and we develop the matching solution, from prototype to small series.

Covers and blankets matched to a specific size or piece of equipment
Heat shields, machine and workstation protection
Pouches, bags and transport enclosures for lithium batteries
Combining several fabrics to balance resistance, flexibility and reflection

AVD technology in action

Aqueous vermiculite dispersion (AVD) is a certified technology for lithium-ion battery fires. It stops cell-to-cell propagation, where conventional extinguishers are ineffective or even dangerous.

Unlike a conventional extinguisher, AVD does not aim to put the battery out: it limits ejections, contains the fire and lets the battery burn out safely. Sprayed as a mist, the agent forms a film that dries instantly; the vermiculite platelets expand, bond together and form a non-combustible barrier, cool the fuel and isolate the cells to stop thermal runaway.

Frequently asked questions: Lith-Ex AVD extinguishers

What is an AVD extinguisher?

An extinguisher using an aqueous vermiculite dispersion (AVD) agent, designed for lithium-ion battery fires, where conventional extinguishers are ineffective or even dangerous.

How does it work?

Sprayed as a mist, the agent forms a film over the fire. The film dries instantly and the vermiculite platelets expand into a non-combustible barrier that isolates the cells from oxygen, absorbs heat and stops thermal runaway.

Does it actually extinguish the battery?

The aim is not to extinguish the battery directly, but to contain the fire, limit ejections and let the battery burn out safely from underneath.

Which sizes are available, and for what use?

6 L (everyday devices); 9 L (same uses, plus first response on electric scooters); 25 L trolley (high capacity for recycling centres, garages and workshops, not for electric vehicles).

Are they approved in Switzerland?

Yes, AVD technology is AEAI approved in Switzerland.

What is the warranty?

Lith-Ex extinguishers are manufactured by EUROFEU and carry a 2-year warranty from delivery against hidden defects.

Is regular servicing required?

No inspection is required during the first 5 years. After that, servicing is carried out under a maintenance contract.

What happens after the extinguisher has been used?

Once discharged, the extinguisher can be reconditioned by a professional: refilling, repressurising with nitrogen and resealing. Charged per unit or covered by a maintenance contract.

The ecell-guard system

Early sensor detection, automatic triggering, deployment of the cover over the vehicle within seconds, containment of flames and controlled venting of pyrolysis gases, all without human intervention. Ypiresia is the approved reseller for Switzerland.

Maquette ecell-guard, parking couvert multilevels

Frequently asked questions: ecell-guard system

What is the ecell-guard system?

An automatic system for detecting and containing lithium battery fires, for covered car parks, warehouses and fleets. Ypiresia is its approved reseller for Switzerland.

How does the system work?

Sensors detect a fire at a very early stage. Within seconds the system automatically deploys a cover over the vehicle: flames smothered, heat contained, pyrolysis gases vented in a controlled way.

Is human intervention needed?

No, everything is automatic. The system protects people, the building and neighbouring vehicles without exposing any responder.

Where can it be installed?

On an individual parking space (Basic version), in an outdoor car park (mobile Carport version), and in covered car parks, warehouses and fleet depots.

How much does it cost?

On request, depending on the configuration: number of spaces, indoor or outdoor, installation options.

Tested, certified, approved

All our products undergo rigorous testing by independent laboratories (SGS, TÜV). Compliance with EN 13501-1 and ISO standards, and AEAI approval. Our vehicle fire blankets comply with DIN SPEC 91489:2024-11.
