Cold-elastic elastomers for reliable rubber ropes at low operating temperatures Cold-elastic elastomers are specially designed to reliably maintain their elasticity and functionality even in sub-zero temperatures. In our production, we always use cold-elastic rubber when rubber ropes need to function reliably under winter conditions, in cold environments, or when exposed to permanent cold. Through targeted material selection and high-quality [...]
High-performance elastomers for maximum performance rubber ropes High-performance elastomers stand for the highest technical requirements, extreme resilience and maximum process reliability. In our rubber rope production, these specialised elastomers are used wherever standard materials such as natural rubber or neoprene reach their limits. High-performance rubber ropes are specifically developed for applications that require permanently high mechanical, thermal or chemical loads. Thanks to precisely matched [...]
Neoprene as an elastomer for our quality rubber ropes Neoprene, chemically known as chloroprene rubber (CR), is a proven synthetic elastomer material for customised, technically sophisticated rubber ropes. In our production, we use neoprene specifically where constant elasticity, high environmental resistance and mechanical reliability are required. The combination of a high-quality neoprene core and precisely matched textile braiding results in neoprene rubber ropes that [...]
Natural rubber as an elastomer for high-quality rubber ropes Natural rubber, technically known as NR (natural rubber), is a proven, renewable elastomer material with outstanding elastic properties. In our rubber rope production, we use natural rubber wherever maximum elasticity, high resilience and particularly dynamic elastic behaviour are required. The precise processing of the natural rubber core and the coordinated textile braiding create [...]
New customisation options thanks to multifunctional 3D printer We recently decided to purchase another device for our rubber cord production: an FDM 3D printer with functions for engraving, laser cutting, digital cutting (vinyl etc.) and drawing/pen mode. With this purchase, we are now able to laser engrave our stop parts, such as pipe sections or cable lugs, with individual labelling [...].
An overview of our rubber types When developing and manufacturing our high-quality rubber ropes, the choice of elastomer material plays a key role in function, durability and performance. Depending on the technical requirements, such as weather resistance, elasticity, temperature tolerance or dynamic behaviour, environmental conditions (e.g. ozone exposure or oils), we use different types of rubber and material-related elastomer concepts. The following [...]
Aramid - tear-resistant and cut-resistant or temperature-resistant When manufacturing our products, we consistently focus on quality and performance - and this starts with the selection of the right yarn, because choosing the right yarn material is a decisive factor for the performance and durability of technical textiles such as our rubber ropes. One of the four specialised yarn types that [...]
Polyethylene (PE) - abrasion-resistant and durable When manufacturing our products, we consistently focus on quality and performance - and this starts with the selection of the right yarn, because choosing the right yarn material is a decisive factor for the performance and durability of technical textiles such as our rubber ropes. One of the four specialised yarn types that we [...]
Sustainability with real impact For us, sustainability means more than environmentally friendly materials, efficient processes or durable products. For us, sustainability also encompasses the idea of how we take responsibility for people in our society. For this reason, we have once again made a conscious decision this year to forego traditional gifts and instead honour our commitment to [...]
Our team makes the difference and we continue to grow A successful year lies behind us. It was characterised by commitment, a wealth of ideas, real team spirit and strong growth. And if there's one thing we've learnt, it's that success doesn't come from machines or processes - it comes from people and communication. Stronger together Whether in production, in the [...]
Polyester (PES) - tensile strength and dimensional stability When manufacturing our products, we consistently focus on quality and performance - and this starts with the selection of the right yarn, because choosing the right yarn material is a decisive factor for the performance and durability of technical textiles such as our rubber ropes. One of the four specialised yarn types that we [...]
Polypropylene (PP) - light, robust and versatile When manufacturing our products, we consistently focus on quality and performance - and this starts with the selection of the right yarn, because choosing the right yarn material is a decisive factor for the performance and durability of technical textiles such as our rubber ropes. One of the four specialised yarn types that [...]
Interface between customers, production and organisation At Expandable, Andreas Neumann GmbH, we attach great importance to precision, quality and reliable processes. Behind these processes are people who keep everything running with expertise and commitment. One of our key people is Maximilian Laimann. In 2022, he successfully completed his training as an industrial clerk with us - a [...]
Two braiding machines - one strong result Our braiding machines are not only efficient individually, but can also work as a team. The result is a rubber cord that has special properties thanks to multiple braiding. This is how double braiding works: first, the first braiding machine produces a rubber cord with the first braid. This rope is then fed via rollers directly into the [...]
Hello, I'm Felix Brosig from Year 9 at the Waldorf School in Haan-Gruiten and I was at the so-called WOW-Day at the rubber rope company Andreas Neumann GmbH. WOW-Day (Waldorf-One-World) takes place once a year. On this day, all pupils from the 5th grade onwards have a day off, but work in a company of their choice. The money that the [...]
People behind the ropes Behind every Expandable product are people who work with passion, expertise and commitment. Our team combines the values of a family business with entrepreneurial innovation. Since 2006, we have been manufacturing customised rubber ropes - ready-made and by the metre - because we work together, develop ideas and take responsibility! Starting [...]
An overview of our yarn technology When manufacturing our products, we consistently focus on quality and performance - and that starts with selecting the right yarn, because choosing the right yarn material is a decisive factor for the performance and durability of technical textiles such as our rubber ropes. In our production process, we focus primarily on [...]
Daniel Neumann becomes second Managing Director, his younger brother Tobias Langensiepen takes over technical management We are very pleased to announce an important personnel change in the management team: Our former authorised signatory, Daniel Neumann, has been appointed as the second managing director of Andreas Neumann GmbH alongside his father Andreas Neumann. With many years of experience, entrepreneurial flair and commitment, Daniel has [...]
On 21 February, the time had come again: the annual audit took place and Daniel spent 10 hours answering the external auditor's every question and showing him every detail of the company. This week, Daniel was then able to receive our new ISO 9001:2015 certificate. We have been continuously certified with this since 2006 and were once again able to [...]
Since the beginning of the year, we have taken a significant step towards sustainability and environmental protection by investing in a photovoltaic system on the roof of our company building
As a company, it is important to us to have a positive impact on society and to take responsibility. That is why we have decided to invest in social causes.
As part of the continuous expansion of our range, we have now also realised metal braiding for a customer.
We are delighted that our apprentice Maximilian Laimann has successfully passed his industrial clerk examination.
On 1 October 2022, we significantly expanded our production and storage space at the site.
Quality management is a high priority for us. We therefore take regular audits as an important impetus to review and improve our processes.
