Our Technologies

L’originalité et la force de notre entreprise : des technologies complémentaires au service de nos clients, pour une offre clé en main !

Thanks to our international footprint (France, Slovakia, Brazil) we offer a flexible and reactive support to our customers’ growth plans and act as partners in their projects.

We support key accounts as well as SMEs (Small and medium-size enterprises) in their search for solutions. We are not only specialized in medium production runs, our process is also perfectly fit for prototype parts and medium size series.

Casting polyurethane

Pioneer of polyurethane casting in France.
Through the casting process, the pre-polymer technology and molding method will ensure the expected properties of Courbis Polyurethanes Courbhane® are met :

• the usual hardness of our products ranges from 25 Shore A to 85 Shore D
• specific target properties: hydrolysis resistance, excellent behaviour under dynamic constraints, as well as resistance…
Development of new materials specifically suited to your requirements : anti-static properties, vibration damping performance…

Our lastest innovation CourbhaPure®, a moca-free standard Polyurethane brand, is combining state of the art durability and a green footprint !
Our process is very flexible, ideally suited to unique parts and medium size series.

Advantages
> Resistance to abrasion
> General mechanical properties
> Load resistance
> Impact resistance
> Resistance to hydrolysis
> Resistance to oils
> High hardness

Sprayed Polyurethane

Thanks to Courbhane® quick polymerisation time, the projection process offers an elastomeric material which can be processed quickly on any part geometry :

• Removable protection of fragile parts (automotive body panels, dashboards, airplane and helicopter parts, as well as elements for boats, rail, tractors, trucks, busses…) to protect parts during the assembly process.

• Anti-abrasive coatings on tribofinition containers, concrete mixing equipment, ducts, conveyors, vibrating bowls, various mechanical parts and tools…
Our process is very flexible, and ideally suited to unique parts and small series.

Silicones

Courbis Coursil ® product range basically includes two types of silicones :
• RTV (Coursil S ® range) : silicones crosslinking at room temperature and used in a casting process = technical parts and semi-finished products.
• EVC (Coursil C ® range) : elastomers crosslinking in hot temperature and compression conditions = technical parts for significant volumes.

Silicone materials are dedicated to withstand high temperature around 180° minimum in continuous use, whilst keeping their outstanding properties regarding flexibility, chemical stability and electrical insulation...

The Coursil ® silicone range offers a wide variety of hardness, ranging from 6 Shore A to 70 Shore A.
We can develop some new materials specifically suited to your requirements.
