Polyurethane is an excellent base material for climbing holds. PU holds are significantly lighter, for example compared to polyester holds, with corresponding advantages in handling and in packaging and transport. Thanks to the high strength and stability of the material, PU climbing holds can be manufactured in very thin wall thicknesses, with an up to 80 percent reduction in material consumption. In addition, polyurethane’s low brittleness makes it more suitable than comparable materials for the design of different grip shapes.
Whether rapeseed oil or sunflower oil, wood waste or sugar: polyols can also be produced on the basis of renewable raw materials. The challenge of the joint development work of allHOLDS was primarily to meet the desired sustainability with the high requirements of climbing holds in terms of stability (compliance with DIN EN 12572-3:2017) and abrasion resistance while using as little material as possible and maximising durability.
The result of the joint cooperation was the development of the climate-friendly allHOLDS Eco-friendly Polyurethane. The new PU material not only meets all the requirements for the production of an extremely stable, robust and durable climbing handle, but also guarantees a high degree of economic efficiency with cycle times of around ten minutes! It is offered to our customers for both hand and machine casting.
