THE PROFESSIONAL APPLICATION
Here you will find explanatory videos to find out more about us and our duranity product and to help you take your first steps towards making your own climbing holds.
If you have any further questions, please feel free to contact us.
Behind duranity is the plastics manufacturer ebalta from Rothenburg ob der Tauber in northern Bavaria. The medium-sized company with around 130 employees has been on the market for 50 years and specialises in highly abrasion-resistant casting resins and blocks. ebalta therefore manufactures the ‘high performance’ product that climbing hold manufacturers need to implement their creative hold ideas.

WHO IS BEHIND DURANITY?
The issue of sustainability is firmly anchored in ebalta's strategy. As a classic ‘plastics company’, our aim is to achieve maximum performance with renewable raw materials. This is also in line with the needs of climbing hold manufacturers, who wanted a sustainable moulding compound.
The polyol component of the duranity polyurethane (PU) casting resin is therefore made from natural oils. No substitutes from renewable sources are yet available for the isocyanate, the second component of PU. The duranity casting compound therefore currently contains 40 per cent renewable raw materials. However, we are researching how to further increase this proportion. We are offsetting the remaining emissions. Our goal: a product that comes from 100 per cent non-fossil sources.

HOW SUSTAINABLE IS DURANITY?
duranity is a polyurethane (PU) moulding resin. In contrast to polyester (PE), thinner wall thicknesses can be produced with this plastic, which saves material and makes the holds nice and light. PU also has a high impact strength, is very abrasion-resistant and has attractive colours.
The duranity moulding compound is available in two versions: L (= slow) and S (= fast). This means that the material can stay in the pot a little longer, giving you more time to cast your holds, or it must be processed quickly and preferably by machine.

WHAT ARE THE BENEFITS OF PU?
In addition to the unusual shapes, modern climbing holds stand out due to their wide variety of colours. With our duranity casting resin, you can also easily implement your ideas in terms of colour. Even two-coloured holds are no problem. Our colour paste is available in 16 different colours and is perfectly matched to the duranity casting resin. It has no influence on the properties of the plastic. Our colours also score highly in terms of durability: indoors anyway, and for outdoor use we offer a special UV stabiliser that protects the material from sunlight.

HOW DOES THE MATERIAL BECOME COLOURED?
One square centimetre of duranity material can hold up to 900 kilos. Recommendations for the wall thickness of the climbing holds are derived from this. In this video, Gregor gives valuable tips based on his many years of experience.

WHICH WALL THICKNESSES ARE APPROPRIATE?
In this video, Gregor explains the ‘ingredients’ you need to make holds. You will learn that it is possible to cast by hand or machine, what happens chemically and why it is so important to post-cure the cast hold in the mould. Gregor also gives you important tips to help you avoid basic mistakes right from the start and achieve the desired result more quickly.

WHAT DO I NEED TO MAKE CLIMBING HOLDS?
The right choice of materials and adherence to the processing parameters influence the abrasion resistance, i.e. how long your hold will last. Clemens also explains in detail and clearly why it is essential to preheat the silicone mould before casting. This also affects the lifespan of the climbing hold.

HOW CAN I INFLUENCE THE ABRASION RESISTANCE?
You don't need expensive equipment to realise your climbing hold ideas with duranity casting compound. We have already made sure during development that our product is adjusted so that it is easy to work with.
Nevertheless, there is a simple but important tip for your workshop: an ideal room temperature of 20 to 23 degrees. According to the motto: Where you feel comfortable, your material will feel comfortable too.

HOW DO I ENSURE OPTIMAL PROCESSING CONDITIONS?
Now let's take a look over the shoulders of the guys from Virgin Grip and show you what holds production looks like in a modern workshop.

WHAT DOES THE HOLD PRODUCTION LOOK LIKE IN PRACTICE?
The story of duranity casting resin began with a request from a climbing hold manufacturer for a specialised product for the production of climbing holds. We brought other manufacturers on board for the development of the ‘hottest material in the world’ (quote from Gregor). This enabled us to jointly develop a moulding compound that is precisely tailored to the needs of a climbing hold manufacturer. In addition, all network partners are united by the topic and the absolute desire for more sustainability.
