Innovation for drive systems: Alzchem offers storage-stable solution for the production of stable pressure tanks with DYHARD®
Demand in the entire transportation sector for lightweight and extremely stable pressure tanks is increasing, driven by the trend toward climate-neutral vehicles and supported globally by increasingly stringent legislation on CO2 reduction: This is also giving a particular boost to the development of alternative CO2-neutral drive systems - such as for fuel cell vehicles.
In the so-called Towpreg technology, carbon fiber strands are pre-impregnated with the complete epoxy resin system and pre-cured. For the described pre-impregnation of the towpregs (carbon fibers), Alzchem has developed a solution consisting of the latent hardener DYHARD® 100S, the accelerator DYHARD® UR500 and the latent additive DYHARD® LA1 - components that combine long shelf life with fast curing. For the storage of the towpregs based on these DYHARD® as well as for their transport to the end processors (winding companies), cooling is no longer required, which in turn saves costs and reduces energy consumption, thus also offering significant advantages from a sustainability perspective. Winding and curing in the cylinder's oven takes place at short notice as required.
This means that towpregs based on DYHARD® have ideal properties for applications such as the production of compressed gas cylinders for motor vehicles with alternative drives, compressed air cylinders for rescue workers or oxygen cylinders for divers.
Alzchem's DYHARD® system solution for towpregs offers three key advantages:
-
A latency of four to five months: With a much longer shelf life, costs for storage and transport are reduced while quality remains consistent.
-
Rapid curing at high temperatures is possible with the DYHARD® solution. For fast winding processes, the system is also OEM-compliant.
-
The DYHARD®-based towpregs have outstanding mechanical properties and excellent adhesion to carbon fibers.

About Alzchem
Alzchem is a globally active specialty chemicals company that is one of the market leaders in most of its fields of activity. Alzchem benefits from the three very different global developments climate change, population growth and longer life expectancy in a unique way. Alzchem products can offer attractive solutions for achieving the resulting social goals in a multitude of different applications.
The company sees interesting growth prospects for itself in the areas of human and animal nutrition and agriculture in particular. As a result of population growth, it is necessary to achieve efficient food production. Pharmaceutical raw materials and creatine products can contribute to a healthy old age as life expectancy increases. Alzchem is facing up to the goal of sustainability arising from climate change in the field of renewable energies and across the entire company. The fields of fine chemicals and metallurgy offer just as great a perspective.
Alzchem Group AG’s broad product range includes dietary supplements, precursors for corona tests and pharmaceutical raw materials. These products are the company's response to global trends and developments. Alzchem is ideally positioned in this respect and considers itself well prepared for an environmental future and global developments.
The company employs around 1,680 people at four production sites in Germany and a plant in Sweden, as well as three sales companies in the USA, China and England. Alzchem generated Group sales of around EUR 542.2 million and EBITDA of around EUR 61.4 million in 2022.
