A low VOC content, high thermal stability and easy handling makes VESTOPLAST® the perfect raw material for hot melts used in interior bonding such as headliners, door panels, dashboards or for insulation felts and car carpets.
For superior adhesion properties on oily or degreased metals the POLYVEST® range contributes to a large variety of Body-in-White adhesives and sealants to be easily applied by robot or manually along car assembly.
High quality two-part PU adhesives for head-lamps can be reached by the flexible and hydro-phobic polymeric binder POLYVEST® HT.
Depending on the target substrates, the VISIOMER® product range offers the right monomers for acrylic based adhesives. Usually those kind of structural adhesives need no further surface preparation.
NOURYBOND® adhesion promoters are essential in automotive sealant, underbody and anti-chip primer formulations, providing unique rheological properties and improved adhesion to electro-deposition primers. Plasticizers like VESTINOL® are able to further enhance adhesion.
1 Hybrid structures metal/plastics
Prepregs based on VESTALITE P 342 pro-vide material-efficient composite solutions by local reinforcement of structural metal parts. Due to high adhesion and controlled reactivity of the resin, bonding and curing can be achieved in a combined fast process step without need for adhesive films.
The reactive adhesive VESTAMELT® increases the bonding of plastic resins on metal inserts. Therefore it saves weight and space in overmolded hybrid structures e.g. in front end carriers or floor panels.
2 Structural parts
Placing reinforcing fibers where needed and overmold it to the final shape: this is the idea of VESTAPE®, unidirectional fiber reinforced tapes with a thermo-plastic matrix like PA or PEEK.
For autoclave, RTM or wet pressing, the high temperature and creep resistance of the rigid foam ROHACELL® is the trouble-shooter for high-end fiber reinforced plastics (FRP) sandwich structures like roofs, engine hoods or battery housings.
In-mold foamed with hom*ogeneous particle distribution, ROHACELL® Triple F offers ready to use complex 3D shaped sandwich cores. With a couple of additives, the performance of resins for FRP can be optimized for the individual requirements of the processes.

AEROXIDE® can improve safety, life-time or capacity when used for separator, anode or cathode of LIB in EV’s.
Electronic components like ignition systems are encapsulated in epoxy resin with the toughener ALBIDUR® to improve the thermomechanical performance and to meet the high demands of harsh environments.
Electronic connectors reach higher temperature resistance if the basic thermo-plastic material is equipped with the crosslinking agent TAICROS®.
6 Tires
ULTRASIL® silica and silanes like Si 69® and Si 363® are making today’s tires safe and environmentally friendly. So called Green Tires with Silica/Silane-technology have proven to have significantly lower rolling resistance, resulting in a reduction in fuel consumption up to 8 % and thus lower CO2 emissions. Additionally, they also have better grip – particularly in wet conditions – which significantly shortens the breaking distance.
POLYVEST® and VESTENAMER® further boost those properties and help to ease the processing.
1 Powertrain
Under the hood, you find high tempera-tures, chemical aggressive fluids and gases, but the high performance polymers VESTAMID® HTplus PPA or VESTAKEEP® PEEK can stand it: As a silent running gear wheel, laser welded electronic housing or lubricant free swivel-joints.

1 Surfaces
To warrant a high durability of the car, lavishly decorated panels, consoles, and operational controls have to retain their appearance over the life of the vehicle. Sweat, skin oil, and cosmetics or sunlight, temperature swings or even cleaning agents can cause damage. Surfaces made of micro-crystalline thermoplastic TROGAMID® are built tough for these requirements. They stand up to sunlight, heat, shock, not to mention cosmetics and other chemicals.
The excellent transparency of ACRYLITE® allows all kinds of coloration or perfect second surface decoration in center stacks or decorative trims and door panels. With an extraordinary haptic it’s ideal for tough pads and other control elements. For very high demands in scratch resistance the system solution CoverForm® is recom-mended.
Spray skins include coatings for the dash-board and other plastic parts. In addition to high resistance, such components need to look and feel good, properties that VESTANAT® IPDI can noticeably improve.Hybridur® polymer dispersions provide excellent wetting and adhesion to a variety of substrates including wood and plastic to provide highly aesthetic, durable coatings.
