Right: The white Endumax fibers on polyester/mylar laminate creates an all-white sail with stretch resistance like a carbon sail. X-Drive Endure sails are made with continuous, corner-to-corner yarns made out of Endumax. Endumax is an Ultra-High Molecular Weight Polyethylene, similar to Spectra® and Dyneema® — fibers known for high strength and durability. While being stretchier than carbon, Endumax fibers stand up to abuse much better. X-Drive Endure sails give club racing performance with the durability cruising sailors require -- all with a clean classic white appearance. Because these sails are made with Endumax and because they have the endurance that is required for successful cruising and shorthanded sailing, we named the new line of sails, X-Drive Endure. According to Teijin, the makers of Endumax; it is made of a special type of UHMWPE (Ultra High Molecular Weight Polyethylene), making it the strongest UHMWPE film available in the world. It also has a higher modulus and better abrasion resistance, UV resistance, creep properties and thermal-aging performance than other UHMWPE fibers. Teijian also says that Endumax is the most sustainable UHMWPE product available, being made in an environmentally friendly, solvent-free process. As a result, the film contains no additional processing aids or solvent residue. And the thermoplastic nature of UHMWPE means that it can also be easily recycled.
