Elkem Silicones ATRiON R&I Saint-Fons

ATRiON R&I center is located in Saint-Fons in Lyon’s Chemical Valley, France.

On July 1st 2021, Elkem Silicones announced the opening of ATRiON, its new Research and Innovation center in Lyon - France. Short for “atrium and innovation”, ATRiON fosters collaborative and agile research work, reflecting the evolution of research towards more open, more multidisciplinary formats.

Innovating and designing together new solutions for a sustainable wold. Reseach & Innovation strating from quartz to silicones material. Strenghtening innovation through wide analytical know-how.

Silicone is an inert synthetic compound that come in a variety of forms (oil, rubber, resin).

Chlorosilane is chemical compounds prepared by reacting silicon powder and methyl chloride (CH3CI) gas through direct synthesis. 

The most common silicone oils are linear polysiloxane compounds, that orient in spiral chains, which easily glide and slip over one another. 

Depending on processing requirements or usage, silicone fluids may be used as 100 % materials, in a diluted form – mostly in halogenated hydrocarbons, aromatic compounds or high-boiling white spirit.

A silicone compound is made up of a hydrophobic particle (generally silica) dispersed in silicone oil, which produces a foam control or antifoam agent used in a great variety of applications.

Silicone emulsions are silicone oils dispersed in an aqueous system. Emulsions are ideal for surface treatments, being easy to apply, and are simple to prepare.

Silicone grease is silicone oil based thickened with a lithium soap.

Silicone resins are relatively low molecular weight polymers with a three-dimensional branched-chain structure.

Silicone elastomers are compounded using reactive, straight chained molecules together with a cross-linking agent and reinforcement to give good mechanical properties (elasticity, absorption, tear strength).

RTV-1 is a one-component, Room Temperature Vulcanization silicone rubber that cures at room temperature. 

RTV-2 silicones are two-component, Room Temperature Vulcanization silicone rubbers, gels or foams.

Heat Cured Rubber is a silicone elastomer formed of straight chains with very high molecular weight.

Liquid Silicone Rubber (LSR) is a two-component system, where long polysiloxane chains are reinforced with specially treated silica.

R&I teams work closely with sustainability team within Elkem and within our Open innovation and partners network to prepare sustainable future and build green transition.
Due to their durability and resistance to weathering, chemicals and high temperatures, silicones extend the lifespan of products.
Extended lifespan minimise waste and support the ambition to reduce the demand for primary materials.
In fact, it has been found that using products made with silicones saves 9 times more greenhouse gases than what was emitted during the manufacture of these silicone materials.
