Rubber profiles
Goods by the metre, cut into pieces or made up into rings and frames
Profiles made of EPDM, NBR and silicone for a wide range of industrial applications
KREMER specialises in rubber profiles that are precisely tailored to your application. The areas in which profiles can be used are extremely diverse. In particular, these include solid and sponge rubber profiles made of EPDM Krevolan®, as well as solid and cellular silicone profiles made of Krevosil® for façade, door and window construction, greenhouse construction and glass construction,
Solid rubber and cellular profiles for plant and mechanical engineering, sanitary engineering, environmental technology, the food sector, the lighting industry, the automotive industry and renewable energies round off the programme.
KREMER works for customers from all these and many other industries. When we talk about rubber profiles, we are usually looking for profiles made from the common and tried-and-tested materials EPDM and silicone.

Rubber profile sections are produced from precisely extruded profiles. In order to produce profile sections of exactly the same length, a reliable cutting machine is required. This is the only way to ensure that the tightest length tolerances can be maintained when cutting rubber profiles to length and, in particular, when cutting sponge rubber profiles to length. What can still be considered easily manageable with solid or solid rubber profiles is a challenge with sponge rubber profiles. When cutting sponge rubber profiles to length, special attention must be paid during the cutting process to the relaxation of the elongation introduced by tension.
Rubber profile sections
We specialise in producing the smallest profile sections - depending on the geometry and hardness of the rubber profiles - from a length of 4 mm. Longer is of course always possible.
Our calculation tools provide a clear overview of the cross-section and length tolerances that apply to rubber profiles and the tolerances that apply to sponge rubber profiles.
After cutting, the cut-to-length profile sections of the rubber profiles or sponge rubber profiles can be manually bonded with cyanoacrylate adhesives to form sealing rings with different diameters. As a rule, the joints of the rubber rings can also be carried out with the aid of tools as impact vulcanisation (injection of a proportion of material). Film vulcanisation (application of a thin layer of material at the joint of the profile to be joined) can only be carried out with silicone profiles.
The production of sealing frames is usually associated with the term corner vulcanisation. Here we have the option of moulding profile corners onto the profile ends and thus creating the perfect contour in the corner area for the function of a profile frame. As a specialist elastomer company, we can carry out mitre cuts for the production of bonded sealing rings and sealing frames.
Professional tip: With the 3D printing process, we can reproduce profile prototypes up to a length of 30cm excellently and efficiently.

Rubber profiles are generally manufactured as continuous lengths and processed into profile sections in an additional work step as required. Depending on the geometry of the profile sections, the rubber profiles can be fitted with self-adhesive film.
The variety of profiles available - from solid solid rubber profiles to hollow chamber and tubular profiles to multi-component rubber profiles - can be found in our EPDM profile catalogue. In addition to rubber profiles, we also manufacture plastic profiles and TPE profiles. The functions that our profiles fulfil are just as varied as the materials. For example, they are used as UV-resistant support profiles for laminate clamps for fastening photovoltaic panels, as temperature-resistant seals in ovens or as anti-squeak profiles in cars to prevent unwanted noise.
The demands on the material and the geometries are very high. There are always requests for our development team that are completely new. Challenges that we love! It is our incentive to find an economical and customised solution for you. So get in touch with KREMER!

Rubber profiles according to drawing? Therefore to KREMER!
Three reasons why we are your ideal supplier for customised rubber profiles:
Sound expertise
Not only customers who already have an exact idea of their rubber profiles appreciate our in-depth expertise. Those who would like technical support from our employees also rely on KREMER's expertise. The rubber profile team at KREMER is able to fully understand your processes and take into account the details and subtleties in order to offer you the best option in every respect after the development process. Thanks to our many years of experience, we can find the ideal solution even for tricky challenges - a combination of service and expertise that has proven itself time and time again throughout our 50-year company history.
Little time required
Another strength that characterises us is our fast, transparent and informative quotations. As important delivery and production processes for most of our customers are linked to the rapid availability of rubber profiles, timing plays a major role in procurement. We therefore operate very efficiently and flexibly: once we have received your enquiry with all the requirements and specifications, you will hear from us within 24 hours during the working week. Once all the parameters have been clarified, we will prepare a quotation at short notice. We always endeavour to achieve the shortest possible delivery times for you.
Highest product quality
Rubber profiles in particular, which can be manufactured in so many possible material variants and shapes, must be 100% customised to the individual application. Accordingly, the quality requirements of our customers are very high - especially with regard to the use of rubber profiles and their process reliability and product quality. KREMER is able to fulfil these strict specifications and product quality requirements at all times because we only use reliable suppliers with whom we and our customers have had good experiences in the past without exception. Not only are we ISO 9001:2015 certified, but we also select our suppliers based on ecological and ethical criteria.

Further information
Simple installation with self-adhesive film
Especially when long sections need to be fitted with profiles, the use of self-adhesive film as an assembly aid is a practical support and simplifies the fixing of the profile during assembly.
Storage time limited
Profile seals equipped with self-adhesive film can only be stored for a limited period of time. Due to the chemical composition of the film, the self-adhesive profile may also have a shorter shelf life. This shelf life is shorter than the warranty period of twelve months for self-adhesive profile seals. Please be sure to observe the storage and processing instructions.
Professional tip: For optimum processing, the profile seals should be stored in an unopened box and processed within six months.
Temperature and processing
- Optimum bonding temperature between 20°C and 30°C in dry rooms.
- Do not process below 10°C.
- Storage temperature at 20°C and approx. 50% relative humidity.
- Ensure that surfaces are clean, dry and, if possible, smooth - this produces the best results.
- Only remove the protective film immediately before use. This prevents adhesion-reducing contamination with dust and moisture.
- It is essential that you ensure even and full-surface contact. The contact pressure must be sufficient and even. Both the hands and the application tools must be free of release agents (especially oils and greases).
- The profile to be fixed should not hang for longer than 30 minutes without support.
- Please note that the maximum adhesive strength is only reached after approx 24 hours in the case of extreme loads on adhesive joints.
- The profiles should be processed in such a way that a permanent stress effect on the bonding is avoided.
Prerequisite for the warranty for self-adhesive products
Self-adhesive profile seals must be processed within six months of delivery, taking into account the above-mentioned storage conditions (temperature, humidity and other processing instructions). We cannot accept any liability / warranty for products processed at a later date.
