Tried-and-tested formulae for automobile manufacture – sustainable and tight.

some cars in a row

Worldwide, there are around 1 billion motor vehicles. And where there are cars, you find products by Sonderhoff. Our foam seals, glues and potting are put to use in over 300 applications in cars.  For example, as dust, chemical and damp protection, for shock absorption or for making durable joins between different substrates.

Quality and safety are our top priority. This holds true for the selection of raw materials and their processing through to the safety of the production plant.

We don’t leave anything to chance, never letting damp, dust, damaging materials or temperature effects create a danger for parts and electronics in the car. Our product systems for foam sealing, gluing and potting are listed by numerous automotive manufacturers. They are given in OEM profiles of requirements and component drawings.

Sonderhoff fulfils the current quality and safety norms

Sonderhoff develops its sealing, gluing and potting systems for vehicles on the basis of the quality and safety norms current in the industry.  ISO/TS 16949 (general requirements and norms of the auto industry on quality management systems), together with the process audit according to VDA 6.3, is also a benchmark to which we adhere. Additionally, the technical qualities of our material systems conform to the house norms of many manufacturers, such as:

  • DBL 5452-13 (Daimler)
  • TL848 (VW)
  • MY 560 (Chrysler/Fiat)

With the constant growth in the complexity of vehicle electrics, the opportunity for faults also grows. Therefore, security-related components must be sealed watertight, glued or potted. Sonderhoff’s foam sealing, gluing and potting systems in polyurethane or silicone prevent ingress of moisture and thereby corrosion of electrics – so often one of the causes of a loss of function. Our products for these uses fulfil ISO 26262 on functional safety in electronics.

We are your point of contact for many automotive uses, such as:

  • Low emission foam seals in the passenger compartment, which fulfil the manufacturer's low emissions requirements
  • Rapidly reacting fast-cure foams for swift further processing of parts, vital for fast-paced, efficient volume production
  • Sealing with polyurethane foam FERMAPOR® K31, with consideration for phenomena such as cold water swelling in foams from 0° to 4° C.

Themes such as emissions reduction in cars, networked autonomous driving, motor electrification and new mobility concepts represent future challenges for auto manufacturers.

Sonderhoff is also your first port of call to find out about the best solutions for sealing, gluing and potting in parts employed towards such uses.
