Seals made from NBR
Customised production with universal material properties
Customised production with universal material properties
You need NBR gaskets and are looking for a supplier who can deliver them to you - customised and made to measure for your sealing application. The environment in which NBR gaskets are used requires material properties such as
- Low compression set
- Sufficiently good low-temperature behaviour (depending on the mixture down to -50°C)
- Good resistance to hydraulic oils, mineral oils, oil-in-water emulsions, water glycols and animal and vegetable oils
Compounds with approvals for use with foodstuffs (FDA, BfR) are also available for the production of NBR gaskets. However, if very high temperature resistance and resistance to ozone, acid gases or high chemical and thermal loads are required, seals made from H-NBR are the ideal choice. Last but not least, HNBR seals also represent an economically interesting alternative to the more expensive fluorine elastomers FPM/FKM.
As a specialist for customised drawing parts, we at KREMER are able to manufacture seals made of NBR that are 100% tailored to your application in accordance with your specifications and material quality requirements. Our product portfolio ranges from
- Injection-moulded seals / moulded parts
- Flat gaskets and
- punched or water jet-cut gaskets, through
- Profile seals through to
- NBR-O-Rings.
When it comes to NBR gaskets according to drawing or sample, please contact us, describe your requirements and wishes and request your customised quotation! We respond quickly and reliably!

Do you have any questions about our products?
Whether O-rings, seals, moulded parts or materials - in the FAQ section you will find answers and lots of further information about the KREMER product range.
It all depends on the dimensions!
The KREMER calculation programmes allow you to calculate the parameters of your application quickly and precisely. Because O-rings, moulded parts or rubber profiles can only function optimally if the dimensions are correct. With just a few clicks, you can carry out installation and tolerance calculations with the KREMER calculation programmes.
Further information
The use of self-adhesive film for elastomer products can be helpful for the user for several reasons. Self-adhesive seals are used, for example, for overhead installation of a seal or to prevent loss during transport of pre-assembled components.
If gaskets, especially profile gaskets with self-adhesive film, are used as an assembly aid for installation, this means that the self-adhesive film has no influence on the function of the gasket after installation.
Punched gaskets self-adhesive on film are a convenient solution that makes installation easier and safer. If the adhesive film is to have a function other than that of a self-adhesive film for mounting purposes, this must be explicitly stated in the enquiry.
Our product consultants will carefully check the information on the intended use and include it in the offer according to the possibilities.
In addition to the proper processing and handling of the self-adhesive film in the seal manufacturer's production, the storage of the elastomer finished products at the customer's premises plays a decisive role in the durability of the self-adhesive elastomer and silicone products.
The right processing
- Ensure sufficient and even contact pressure.
- Processing tools (including hands) must be free of release agent.
- In the case of extreme loads on bonded joints, it should be noted that the maximum adhesive strength is only reached after approx. 24 hours.
- Avoid permanent tension on the bond.
Underground:
- Do not apply to surfaces containing silicones, paraffins or waxes.
- Do not use paints with adhesion-reducing additives.
- Ensure freedom from dust.
- Ensure freedom from plasticisers.
- Ensure dry surfaces.
- Cover as smooth, closed surfaces as possible.
- Exclude chemical reactions of the surfaces.
Temperatur:
- The optimum bonding temperature is between 20 and 30°C in dry rooms.
- If possible, do not work below 10°C.
- Storage temperature at 18°C and approx. 55% relative humidity.
Influences that impair the adhesive strength of the self-adhesive film:
- High humidity, grease, oil, dust and/or dirt on the surfaces of the parts to be bonded.
- Plasticiser migration.
- Improper storage (deviating from DIN 7716).
Storage and shelf life
As a general rule, the following applies to self-adhesive Seals only a limited shelf life can be assumed.
The shelf life of the film may be shorter than the warranty period of 12 months for self-adhesive products.
It is therefore particularly important that the storage and processing instructions are observed. We recommend processing the self-adhesive products within six months.
Warranty conditions "Self-adhesive products"
The product must be processed within six months of delivery, taking into account the above-mentioned storage temperature, humidity and processing instructions. No liability/warranty can be accepted for products processed at a later date.
