Innovative materials - customised to your individual requirements
The requirements placed on cable systems are as varied as the industries in which they are used. As an experienced partner to industry, STAUFF has always made it its mission to develop solutions that go far beyond the standard.
Our clamps ensure secure, durable and efficient fastening of cables worldwide - adapted to a wide range of conditions.
A milestone in our development was the introduction of polypropylene (PP) as the standard material for our clamp bodies. With this step, we have set standards in terms of functionality, cost-effectiveness and reliability. But at STAUFF, innovation does not end with the standard: in close co-operation with our customers, we have developed a comprehensive portfolio of materials that specifically addresses special requirements.
Whether for extreme temperatures, aggressive media or high mechanical loads - every material in our range is optimised for the specific benefit to our customers. The constant further development of new materials, such as the latest sustainable material PP-ECO made from recycled polypropylene, emphasises our commitment to forward-looking, resource-saving solutions.
Thanks to this consistent customer focus, we now offer one of the widest ranges of materials on the market - and the ideal clamp for almost every application.
We would like to introduce you to the entire range of materials for our clamps. But we'll start with the classics: the tried-and-tested and established standard materials are at the heart of the range and are ideal for a wide variety of applications. We will then move on to special materials and their properties and applications.
Polypropylene, PP for short, has been the established standard material for STAUFF clamp bodies in a wide range of series and designs for many years. Its green colour stands for reliable, proven material quality. It remains permanently dimensionally stable and resistant over a wide temperature range from -30 °C to +90 °C.
An outstanding advantage of PP is its resistance to water: it absorbs practically no moisture and does not swell, which is particularly advantageous when installing in humid environments. However, it should be noted that the material is only partially resistant to mineral oils commonly used in hydraulics at high temperatures. Permanent, extensive contact can impair the mechanical properties.
Essential properties of PP:
Colour: Green
Temperature range: -30 °C to +90 °C (permanent), short-term up to +110 °C
Resistant to water, limited resistance to mineral oils
Good chemical resistance and impact strength
Thanks to its economic advantages and versatility, polypropylene remains the first choice for numerous standard applications in mechanical engineering, hydraulics and stationary installations.
In addition to our standard green polypropylene, we also offer the black PP-BK variant in many cases. It is technologically based on the same material and retains all the positive properties - such as high impact strength, temperature resistance and water resistance.
The decisive difference lies in the improved UV resistance: the black colouring significantly increases protection against solar radiation, making PP-BK particularly suitable for outdoor applications.
Key properties of PP-BK:
Colour: Black
Temperature range: -30 °C to +90 °C (permanent)
Improved UV resistance with the same mechanical performance as PP
PP-BK significantly extends the range of applications for polypropylene and makes the material even more versatile for demanding outdoor environments.
Polyamide (PA), recognisable by its black colouring, is the ideal alternative to polypropylene when the requirements for mechanical strength and resistance increase. Its excellent UV stability is particularly noteworthy, making PA the preferred choice for outdoor applications. It covers a wide temperature range from -40 °C to +120 °C and can even withstand up to +140 °C for short periods.
In contrast to PP, polyamide offers improved resistance to long-term contact with mineral oils, which are widely used in hydraulics. However, PA reacts more sensitively to contact with water: Permanent exposure can impair the mechanical properties, as PA can absorb up to 10 % water.
Essential properties of PA:
Colour: Black
Temperature range: -40 °C to +120 °C (permanent), short-term up to +140 °C
High UV and weather resistance
Resistant to mineral oils, limited resistance to water
Polyamide is used wherever mechanical robustness and resistance to harsh environmental conditions are required - for example in mobile machinery, agricultural technology or demanding outdoor installations.
Aluminium (AL) impresses with its silvery-grey, shiny metallic surface and is the preferred material when maximum dimensional stability is required. With its enormous mechanical strength and the ability to permanently withstand temperatures of up to 300 °C, aluminium opens up a wide range of applications, even under extreme conditions.
Its excellent resistance to common chemicals and environmental influences makes aluminium a particularly durable material. However, caution is required when working with stainless steel components: Electrochemical reactions can lead to contact corrosion. In addition, aluminium clamp bodies are around four to five times heavier than comparable plastic solutions.
Key properties of AL:
Colour: silvery-grey, shiny metallic
Temperature range: Up to +300 °C (permanent)
Excellent resistance to chemicals and weathering
Risk of contact corrosion when combined with stainless steel
Aluminium is the ideal choice for particularly robust applications, for example in the oil and gas industry, in shipbuilding or in high-temperature environments.
Thermoplastic elastomer (SA) is the first choice when particularly gentle fastening of cables is required. The black material combines excellent vibration-damping properties with a balanced level of holding force. A hardness grade of 87 Shore A is used as standard, which offers the best compromise between flexibility and mechanical stability.
SA clamp bodies also compensate for minimal tolerance deviations in cable diameters better than harder materials. The material is resistant to water and is suitable for a permanent temperature range of -40 °C to +125 °C. In terms of mineral oil resistance, SA has similar properties to polypropylene: extensive, permanent contact can impair mechanical performance.
Key properties of SA:
Colour: Black
Temperature range: -40 °C to +125 °C (permanent)
Vibration-damping and tolerant of dimensional deviations
Resistant to water, limited resistance to mineral oils
Thermoplastic elastomer offers the perfect solution for sensitive systems and installations where a high level of vibration and noise insulation is required in addition to a secure hold.

PA-EX is a clamp that has been specially developed for use in hazardous areas, i.e. potentially explosive atmospheres. Its special feature is its electrical conductivity.
Properties:
Safe operation in EX areas: Thanks to their defined electrical conductivity, PA-EX clamps contribute to the dissipation of electrostatic potentials and increase safety in potentially explosive environments.
Tested quality: The material properties have been independently documented by TÜV and comply with international IEC standards developed by the International Electrotechnical Commission.
Prevention of contact corrosion: PA-EX is used where metal or aluminium clamps reach their limits in certain applications. This is because direct contact between aluminium (clamps) and stainless steel (pipe) can lead to contact corrosion. This is prevented by the new material.
Customised production: Manufactured on customer request and specially adapted to the requirements of the respective area of application, PA-EX fulfils individual requirements and thus offers greater flexibility.
Applications:
Hydrogen systems
Tank farms in the chemical industry
Refineries
petrol stations
Biogas plants
Underground mining
Industrial suction systems
Processing of bulk materials such as powder, granulate or cement
