Let’s get creative

GOOD IS NEVER GOOD ENOUGH

The­re are good rea­sons why lea­ding manu­fac­tu­rers from indus­tries like auto­mo­ti­ve, Indus­try 4.0 and aero­space count on the inspi­ra­ti­on and ambi­ti­on of our glo­bal R&D team. They all appre­cia­te the open atti­tu­de and inno­va­ti­ve start-up men­ta­li­ty at Von Roll.

The results are visio­na­ry solu­ti­ons that pro­vi­de strong advan­ta­ges for our cus­to­mers in their markets.

Get­ting the che­mi­stry right.

With a top team, lea­ding-edge ana­ly­tics and AI-based tools, we are alrea­dy working today on the che­mi­stry of tomor­row. Our Resins Lab is focu­sed on three key are­as: impro­ved tech­ni­cal func­tio­n­a­li­ty, sim­pli­fied indus­tri­al pro­cessa­bi­li­ty and maxi­mum eco­lo­gi­cal compatibility.

Sili­co­ne-free up to more than 150 °C

For years, the auto­mo­ti­ve indus­try has been loo­king for alter­na­ti­ves to sili­co­ne resins to pro­tect elec­tro­nic con­trol­lers. Our ans­wer: a sili­co­ne-free poly­bu­ta­di­e­ne pot­ting resin with a so far unmat­ched tem­pe­ra­tu­re resis­tance of over 150 °C.

Com­pa­red to sili­co­ne-based pro­ducts, this resin is par­ti­cu­lar­ly cost-effi­ci­ent and high-per­for­mance. In addi­ti­on, it fea­tures high ther­mal con­duc­ti­vi­ty, mecha­ni­cal resis­tance and very good envi­ron­men­tal com­pa­ti­bi­li­ty — without the use of hazar­dous sub­s­tan­ces sub­ject to labe­ling requirements.

Our imp­reg­na­ting resins — a boos­ter for lar­ge seri­al productions

Our new epo­xy-based Dol­ph’s® imp­reg­na­ting resin with excel­lent ther­mal, che­mi­cal and mecha­ni­cal pro­per­ties is espe­cial­ly sui­ta­ble for the insu­la­ti­on and mecha­ni­cal rein­for­ce­ment of win­dings for high­ly stres­sed electric motors in all-electric and hybrid vehi­cles. Due to its high reac­ti­vi­ty and rapid curing, it allows extre­me­ly short cycle times in the pro­duc­tion process.

Green resins — the envi­ron­ment will say Thank You.

Supe­ri­or per­for­mance and maxi­mum envi­ron­men­tal com­pa­ti­bi­li­ty are not a con­tra­dic­tion to Von Roll! Our Dol­ph’s® brand has been pionee­ring the deve­lo­p­ment of high-per­for­mance green resins for more than 50 years.

The jour­ney con­ti­nues: we invest a lot to per­ma­nent­ly opti­mi­ze the envi­ron­men­tal com­pa­ti­bi­li­ty of our ent­i­re resin port­fo­lio. Avoiding sol­vents and hazar­dous sub­s­tan­ces does not only help the envi­ron­ment. It sim­pli­fies indus­tri­al app­li­ca­ti­ons and redu­ces pro­ces­sing costs.

Cur­rent sta­tus: The majo­ri­ty of our pro­ducts alrea­dy con­tains no or only very low levels of sol­vents and hazar­dous sub­s­tan­ces; some of our pro­ducts are even com­ple­te­ly label-free.

Lon­ger ran­ge. More safe­ty.

Fur­ther tech­ni­cal advan­ces are nee­ded for the final bre­akthrough of elec­tro­mo­bi­li­ty. We are making major con­tri­bu­ti­ons to this area: In the eDri­ve Labo­ra­to­ry of the Von Roll Insti­tu­te, our experts are deve­lo­ping new solu­ti­ons to mas­si­ve­ly incre­a­se the safe­ty, effi­ci­en­cy and ser­vice cycle of motors and batteries.

Impro­ving the electri­cal and ther­mal design remains the key here. Our cus­to­mers bene­fit from our more than 100 years of know-how in the engi­nee­ring of electri­cal sys­tems and advan­ced composites.

E‑motors with maxi­mum efficiency

For a noti­ce­ab­le exten­si­on in ran­ge, it is necessa­ry to design not only more power­ful bat­te­ries, but also more ener­gy-effi­ci­ent drives.

Our new insu­la­ti­on sys­tems will enab­le a revo­lu­tio­na­ry new class of high­ly effi­ci­ent, com­pact and extre­me­ly dura­ble e‑motors. Com­bi­ning high-level pro­tec­tion against par­ti­al dischar­ge with excel­lent ther­mal con­duc­ti­vi­ty, sets the sta­ge for the 800 V dri­ves of the future.

Bat­te­ries — solid power

The gro­wing ener­gy den­si­ty in vehi­cle bat­te­ries pla­ces high deman­ds on ther­mal manage­ment. Ope­ra­tio­nal heat must be dis­si­pa­ted effec­tively — and in the event of ther­mal over­load, chain reac­tions from cell to cell must be prevented.

Our Shield T pro­ducts sepa­ra­te the indi­vi­du­al cells wit­hin the vehi­cle bat­te­ry in both electri­cal and ther­mal dimen­si­ons. They pro­vi­de a high­ly effec­ti­ve bar­ri­er while kee­ping weight and volu­me to a mini­mum. At the same time, they are high­ly fle­xi­ble in adap­ting to the size of the cells, which varies depen­ding on the bat­te­ry’s level of char­ge. Extre­me­ly pre­cise and mil­li­on times over.

Advan­ced Mate­ri­als Lab — Power­ful stuff for hea­vy-duty applications.

Our com­po­si­tes are desi­gned to hand­le mecha­ni­cal and ther­mal stress with ease — and for long-term use. The ground­work for this is being rese­ar­ched in our Com­po­si­tes Lab.

This is whe­re we deve­lop, among other things, pionee­ring solu­ti­ons for bat­te­ry pro­tec­tion in electric vehi­cles, ther­mal pro­tec­tion mate­ri­als for indus­tri­al ovens and pres­ses, pro­ducts for bal­listic app­li­ca­ti­ons and cer­ti­fied solu­ti­ons for avia­ti­on and rail transport.

Arti­fi­cial intel­li­gence to dis­co­ver new solutions

Our che­mi­cal engi­neers have lea­ding exper­ti­se in resin tech­no­lo­gies — and they use advan­ced methods: for examp­le, an AI based tool deve­lo­ped in col­la­bo­ra­ti­on with exter­nal sci­en­tists. The use of arti­fi­cial intel­li­gence is a very power­ful gate­way to new discoveries.

One examp­le of suc­cess­ful AI-sup­por­ted deve­lo­p­ment is our EP200 Nxt­Gen resin sys­tem for Pre­p­res and Core Fil­lers. It pro­vi­des the foun­da­ti­on for our inno­va­ti­ve aero­space pro­ducts. The expo­xy resin out­per­forms con­ven­tio­nal phe­n­o­lic resins in terms of envi­ron­men­tal and health pro­tec­tion. At the same time, it exceeds the per­for­mance of cur­rent mar­ket solu­ti­ons regar­ding mecha­ni­cal pro­per­ties, anti-fire per­for­mance and sim­pli­ci­ty of pro­ces­sing. In addi­ti­on, the EP200 resin sys­tem fea­tures excel­lent shelf life at room temperature.
