Vertex climbing holds are made of Polyurethane resin. (PU)
This material has some more advantages compared with Polyester (PE)
- PU is light and flexible and therefore can be used for all type of structure, specific design, and shape
- PU has better resistance to impacts.
Vertex climbing holds use the latest, revolutionary formula of Polyurethane resin Dannom♦nd.
Dannom♦nd is a high-performance pure Polyurethane used primarily in the production of indoor climbing holds. Characteristics like higher wear resistance, bright colors, dry soft texture and superior strength make it the first choice material for Climbing holds. Route setters and gym owners alike appreciate the long life and ease of route setting it imparts in the holds.
♦ Wear Resistance
Dannom♦nd material combined with a relatively rough texture can create a very long lasting textured hold.
Until now the main disadvantage of Polyurethane climbing holds in comparison to polyester, has been wear resistance. Dannom♦nd changes the dynamic.
The key to developing wear resistant materials is to understand what is happening during the wear process – when holds are on the climbing wall and being climbed on. Composite X developed a test machine that creates similar conditions to the climbing wall and is able to give a comparative result within an hour. The test samples are worn down. The samples that lose the least mass during the test are the best materials.
Composite X compared the results of the Dannom♦nd formula with that of many existing hold formulations and the difference in results were quite revealing.
Here are a few examples. Results are in mg Loss.
- Competitor 1 210mg
- Competitor 2 80mg
- Competitor 3 350mg
- CX 510. 150mg
- Dannom♦nd. 15mg
♦ Skin friendly
Dannom♦nd wears down your skin less than virtually all other climbing hold materials. This allows for longer training sessions.
Safety is built into Dannom♦nd. Unlike the majority of materials used for Climbing holds – Dannom♦nd will not crack and give rise to a sudden safety issue – rather it will bend if put under extreme conditions. Dannom♦nd has extremely high Impact and strength resistance even in badly designed climbing holds. Its superior properties can to some degree absorb and make safe design errors. Holds made from Dannom♦nd are suitable on almost all surfaces from plywood to concrete.
The use of the first-rate type of polyurethane and careful control of every stage of producing process make Vertex climbing holds of top quality.
