Silicone Hoses for Machinery, Plants, and Automotive Engineering

NovaNox® silicone hoses are manufactured from VMQ (silicone rubber) or EPDM (ethylene propylene diene rubber). They are flexible, dimensionally stable, and offer a long service life combined with good weather resistance. As high temperatures can occur in machinery, plants, and vehicles, NovaNox® silicone hoses are designed to withstand temperatures from -50°C to +200°C without issues. Due to the excellent temperature resistance of silicone hoses, they remain flexible even in sub-zero temperatures and can also briefly withstand temperature peaks of +220°C due to their heat resistance.

Furthermore, these silicone hoses are resistant to media such as acids, alkalis, and chemicals. In addition to all these benefits, NovaNox® silicone hoses offer another decisive advantage: VMQ (silicone rubber) is not only durable but also incredibly robust, preventing wear even during continuous operation of your machinery, plants, and vehicles.

Given their diverse properties, silicone hoses can be used across a wide range of applications in machinery, plants, and automotive engineering. They are therefore suitable for many uses. Our product portfolio of silicone hoses includes fuel cell hoses, cooling water hoses, and charge air hoses.

As THE system supplier for machinery, plants, and automotive engineering, we provide custom-made silicone hoses to optimise your machinery, plants, and vehicles.

The Purpose of Silicone Hoses

NovaNox® silicone hoses offer numerous advantages. They can be designed to optimally fill installation spaces with complex geometries. While they excel with simple and quick installation and extreme weight savings, silicone hoses are highly durable. This durability is further enhanced by their smooth inner surfaces. These also ensure higher performance, better flow, and increased safety. Silicone hoses are also pressure- and vacuum-resistant, as well as resilient against moisture, UV radiation, and harsh weather conditions. They protect electrical equipment or sensitive cables from impact, moisture, and heat, thereby securing the performance of surrounding components.

Another advantage is the noise reduction achieved through the use of silicone hoses. We have further elaborated on the process and benefits of noise reduction in a practical example.

You are free to choose what you need. We offer silicone hoses with or without fabric reinforcement. Furthermore, you can select from a wide range of colour options. The different colours can be important if you have various circuits, helping you maintain an overview. If required, you can also order the hoses in your corporate colour to achieve a better promotional effect.

The most popular colours are:

• Black
• Blue
• Red
• Yellow
• Transparent

Naturally, there is also the option to add your company logo or other inscriptions to the hoses.

Silicone Hoses with Fabric Reinforcement

We offer standard silicone hoses in various sizes. From metre-long hoses and super-flexible silicone hoses to silicone bends, silicone connectors, reducers, as well as beaded connectors or silicone T-pieces – we have everything you could desire. Whether for standardisation in series production or as a quick replacement part, a NovaNox® standard silicone hose is the optimal solution for short-term component supply. We stock all these products in various diameters and wall thicknesses for you. What unites them all is that these silicone hoses have been equipped with fabric reinforcement for increased stability. We offer silicone bends with 45°, 90°, 135°, and 180°, as well as reducing bends with 45° and 90°.

NovaNox® silicone hoses, connectors, or elbows can be used at continuous temperatures from -40 to 180°C. Brief temperature peaks of up to 200°C pose no problem for these silicone hoses. They can be used as fuel cell hoses, cooling water hoses, or charge air hoses. With their help, existing pipelines can be connected, and thanks to their flexibility, even complex installation situations can be easily managed.

Preparation

To manufacture wound silicone hoses, an exact copy of the original steel mould is made at the beginning of the production process. At NovaNox®, thanks to our many years of experience in the silicone industry, we already possess hundreds of initial moulds. This variety enables us to produce standard parts quickly and efficiently.

Before the actual winding of the silicone hoses, careful material preparation is required. For this purpose, the raw material is first mixed with high-quality colour pigments. Subsequently, the material is rolled multiple times until a uniform layer of approximately 1 mm thickness is formed. This layer is then rolled again together with a polyester inlay to provide additional strength to the hose. The resulting layers are specifically cut to the respective hose specifications.

Now, the individual layers are applied to the steel mould. When manufacturing standard parts, we use at least four layers to ensure sufficient safety and stability of the component. The number of layers can vary depending on the specific requirements of the hose.

Taping

To compensate for rough unevenness of the hose and to achieve a perfectly smooth and glossy surface, "taping" is employed. This is an important process where a special, thin adhesive tape is wrapped around the hose under pressure and heat. Mastering this technique requires several months of training. Simultaneously, this process gives the hose its characteristic name "wound silicone hose."

Vulcanisation

After "banding," the hose is vulcanised, meaning it undergoes heat treatment to acquire its final shape. This vulcanisation ensures that the hose permanently retains its form and exhibits high resistance to various environmental influences. Once the hose has sufficiently cooled, it is ready for the final production step.

Finishing

In this final step, the tape is removed to expose the finished hose. With the aid of chemicals and some leverage, the hose is released from the steel mould. The last step involves simply trimming the edges of the hose cleanly. For this, we use a specially developed device that works with a utility knife and precisely cuts the edges.

After this elaborate manufacturing process, NovaNox® silicone hoses are ready for use in various applications, be it in the automotive industry, vehicle construction, or other sectors where high-quality silicone hoses are required.

Advantages over Extruded Hoses

• Higher dimensional accuracy
• Higher operating pressures
• Better resistance to environmental influences
• More complex geometries possible

The Heat Resistance of a Silicone Hose

Another exciting aspect of silicone hoses is their exceptional heat resistance. When it comes to high-temperature applications, our hoses are the first choice for companies requiring reliability and performance.

With heat resistance from -50°C to +200°C, and even +220°C for short periods, a silicone hose has a wide range of applications. We ensure that your process continues to run smoothly, even if temperatures should rise.

NovaNox® silicone hoses made from VMQ or EPDM can meet a variety of international conformity standards, meaning they can be installed in your plant according to the relevant specifications and guidelines. Firstly, the silicone hoses can be manufactured to be RoHS-compliant, which stands for Restriction of Hazardous Substances. This restricts hazardous substances in electrical and electronic equipment, preventing hazardous substances from entering the environment during subsequent recycling. Furthermore, NovaNox® silicone hoses can be manufactured to be REACH-compliant. REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals. REACH conformity therefore ensures that the chemicals used in manufacturing are safely handled and pose no threat to people or the environment at any time. In addition to common EU standards, our silicone hoses can also be manufactured according to US TSCA and FDA standards. The Toxic Substances Control Act (TSCA) monitors and restricts hazardous substances used. The FDA ensures food compatibility.
