From uni­que che­mi­stry to machined parts

HIGH-PER­FOR­MANCE COM­PO­SI­TES FOR ALL DUTIES

Com­po­site mate­ri­als are used in many indus­trial app­li­ca­ti­ons to rein­force com­pon­ents or struc­tu­ral ele­ments. For this pur­pose, they must fea­ture very uni­que mecha­ni­cal, ther­mal and electri­cal pro­per­ties. We achieve and com­bine these in such a cle­ver way that no requi­re­ments are left unful­fil­led. The result: our pro­ducts deli­ver top per­for­mance even in the most chal­len­ging environments.

No mat­ter what par­ti­cu­lar com­po­site mate­rial you need: Our R&D engi­neers will find the per­fect solution.

360° Exper­tise

Engi­nee­ring from A to Z

Our experts can handle the ent­ire value chain — from the deve­lo­p­ment of resin for­mu­la­ti­ons and manu­fac­tu­ring pro­cess to the machi­ning of ready-to-use components.

 

Com­po­si­tes solu­ti­ons — fit for purpose

The chemistry is right

The che­mi­stry is right 

Our che­mi­stry experts are con­stantly inven­ting new resin for­mu­la­ti­ons. In com­bi­na­tion with the latest pro­duc­tion pro­ces­ses, this results in a wide range of epoxy, phe­n­o­lic, poly­es­ter and sili­cone resins. An excel­lent back­bone for lami­na­tes with the hig­hest fle­xi­bi­lity and excel­lent tech­ni­cal properties.

Advanced impregnation technologies

Advan­ced imp­reg­na­tion technologies 

In our modern pro­duc­tion faci­li­ties, we use a wide range of imp­reg­na­tion tech­no­lo­gies — e.g. dip coa­ting, kiss coa­ting or trans­fer coa­ting. Thanks to extra-wide imp­reg­na­tion lines and strictly con­trol­led cli­ma­tic con­di­ti­ons, we achieve maxi­mum pro­duc­ti­vity and quality.

Molding in all dimensions

Mol­ding in all dimensions 

In our high-/low-pres­sure and con­ti­nuous pres­ses, we pro­duce she­ets for a wide range of indus­trial app­li­ca­ti­ons. We also cover large for­mats up to 4 m² with pres­su­res of over 12 MPa. The she­ets are also avail­able unma­chined as semi-finis­hed products.

Machining for any batch size

Machi­ning for any batch size 

Using state-of-the-art mil­ling and grin­ding tech­no­logy, we manu­fac­ture indi­vi­dual parts and com­plex assem­blies from our com­po­site mate­ri­als. Our engi­neers sup­port you from pro­to­typ­ing to serial pro­duc­tion — to meet the hig­hest requi­re­ments for tole­ran­ces and qua­lity. Our sites are cer­ti­fied to sup­ply the aero­space and auto­mo­tive industries.

Our variety of products

Prep­regs

Von Roll has a broad port­fo­lio of pre-imp­reg­na­ted lami­na­tes with spe­ci­fic pro­per­ties for a wide range of indus­trial app­li­ca­ti­ons. This inclu­des stan­dard gra­des as well as highly spe­ci­fic solu­ti­ons for spe­cial requirements.

We set the hig­hest stan­dards through our own brands.

Vetro­nite® prep­regs can be used for a wide range of indus­trial app­li­ca­ti­ons where resis­tance to mecha­ni­cal, electri­cal, and ther­mal stres­ses as well as flame retar­dant and che­mi­cal resistant pro­per­ties are required.

Vetrof­er­rite® prep­regs are used for com­pres­sion mol­ded parts that require magne­tic per­mea­bi­lity and high ther­mal and mecha­ni­cal sta­bi­lity, such as magne­tic slot wed­ges in electric motors.

Our Nxt­Gen epoxy prep­regs are par­ti­cu­larly sui­ta­ble for aero­space app­li­ca­ti­ons due to excel­lent mecha­ni­cal and FST properties.

  • Car­bon fab­ric: ECG Car­bon Prep­regs are used for indus­trial app­li­ca­ti­ons where extre­mely high mecha­ni­cal pro­per­ties and a high elastic modu­lus are required.
  • Cot­ton fab­ric: Cane­vas­ite® prep­regs are used for com­pres­sion mol­dings where high mecha­ni­cal strength and excel­lent anti-fric­tion pro­per­ties are desired.
  • Paper: Del­lite® prep­regs, a good choice for press-mol­ded parts requi­ring good electri­cal resis­tance pro­per­ties and are machined by die-cutting.
  • Ara­mid: Dur­ap­reg® prep­regs are best sui­ted for mol­ded com­pon­ents in defense and secu­rity app­li­ca­ti­ons due to excel­lent bal­listic per­for­mance, light weight, and good flame resistance.

She­ets

Lami­na­tes or laye­red com­po­si­tes are pro­du­ced using high and low pres­sure technologies.

They are based on our prep­regs made of various rein­for­ce­ments (e.g. glass, car­bon, cot­ton, paper, ara­mid) and cor­re­spon­ding resin sys­tems (e.g. epoxy, phe­n­o­lic, sili­cone). Our she­ets are used in a wide range of indus­trial, electri­cal and ther­mal applications.

Ther­mal insu­la­tion is essen­tial for the energy effi­ci­ency, func­tio­n­a­lity, and ser­vice life of indus­trial pres­ses, but also for the pro­tec­tion of bat­te­ries for e‑mobility. Excel­lent heat dis­si­pa­tion is a key con­cern in many machi­nes and devices.

  • Vetro­therm® and Pami­therm® are cha­rac­te­ri­zed by their high ther­mal, che­mi­cal and pres­sure resistance. 
  • Shield T® are par­ti­cu­larly sui­ta­ble for ther­mal and fire pro­tec­tion of bat­te­ries for e‑mobility.
  • Vetro­nite® HTC is a spe­cial mate­rial with very high ther­mal con­duc­ti­vity for app­li­ca­ti­ons in indus­trial equip­ment manufacturing.

Our halo­gen-free com­po­site mate­ri­als are used in many electri­cal app­li­ca­ti­ons, such as gene­ra­tors, motors, trans­for­mers, and switch­gear. They are cha­rac­te­ri­zed by their high electri­cal resis­tance com­bi­ned with high mecha­ni­cal and ther­mal resis­tance as well as very good magne­tic per­mea­bi­lity and their flame retar­dant and anti­sta­tic properties.

  • Vetro­nite® G11 is an all-roun­der for equip­ment manu­fac­tu­ring with its very high electri­cal resis­tance com­bi­ned with high mecha­ni­cal and ther­mal performance.

  • Dur­a­pol® F200 SMC is cha­rac­te­ri­zed by its excel­lent pro­cessa­bi­lity com­bi­ned with very good electri­cal insu­la­tion and flame retar­dancy and is often used in trans­for­mers and switchgear.
  • Vetro­nite® EGS 619, EGS AS and EGS T23 AS are a group of electri­cal insu­la­ting mate­ri­als with good anti­sta­tic pro­per­ties. These flame-retar­dant mate­ri­als are par­ti­cu­larly sui­ta­ble for elec­tro­nic applications.

We have a wide range of pier­cing and bul­let resistant lami­na­tes for app­li­ca­ti­ons in per­so­nal and vehi­cle pro­tec­tion as well as for impact pro­tec­tion in high-speed transportation.

  • Dur­ap­reg® is par­ti­cu­larly sui­ta­ble for per­so­nal pro­tec­tion app­li­ca­ti­ons due to its ara­mid fab­ric base.
  • Poly­ethy­lene-based Para-Lite® 65400 is ideal for vehi­cle protection.
  • Para-Lite® PGR 20 is our vehi­cle and buil­ding pro­tec­tion based on a spe­cial glass fabric.
  • Para-Lite® Flex is the fle­xi­ble bal­listic solu­tion made of ara­mid fab­ric and a highly fle­xi­ble rub­ber resin sys­tem. It is the­re­fore par­ti­cu­larly sui­ta­ble for lining vehicles.

Our com­po­si­tes are indi­vi­du­ally tailo­red to their app­li­ca­ti­ons. Our port­fo­lio com­pri­ses among others 1. glass fab­ric high-pres­sure lami­na­tes for high mecha­ni­cal, che­mi­cal and ther­mal resis­tance, electri­cal insu­la­tion, and flame-retar­dant pro­per­ties, 2. car­bon com­pon­ents for maxi­mum mecha­ni­cal strength, and 3. ara­mid fiber or cot­ton fab­rics for sli­ding and wear properties.

  • Vetro­nite® G11 is an all-roun­der for indus­trial equip­ment engi­nee­ring having very high electri­cal resis­tance com­bi­ned with high mecha­ni­cal and ther­mal performance.

  • Vetro­nite® MAT com­bi­nes the advan­ta­ges of paper and glass fab­ric. It is par­ti­cu­larly sui­ta­ble for die cut­ting applications.
  • Doc­tor Blade Car­bon is a spe­cial qua­lity of our doc­tor bla­des for the paper indus­try. It is cha­rac­te­ri­zed by a par­ti­cu­larly high mecha­ni­cal strength.
  • AR 600 P01, due to the ara­mid fab­ric, offers top anti-fric­tion and wear pro­per­ties com­bi­ned with high mecha­ni­cal strength for vanes and sli­des in com­pres­sors and pumps.

Machined parts

As a full-ser­vice pro­vi­der, our skills also include the pro­duc­tion of ready-to-use com­pon­ents. Machined parts are tailor-made from our com­po­site mate­ri­als accord­ing to cus­to­mer spe­ci­fi­ca­ti­ons and tech­ni­cal drawings. They fea­ture the same excel­lent tech­ni­cal pro­per­ties as the semi-finis­hed pro­ducts. In our machi­ning com­pe­tence cen­ter, finis­hed parts are manu­fac­tu­red care­fully and with very tight tolerances.
