A division of Entropy Sports of Santa Monica uses the advanced epoxy system Hybtonite including Baytubes carbon nanotubes for a new line of custom-made surfboards.
Amroy Europe Ltd. of Lahti, Finland, supplies the epoxy, which incorporates carbon nanotubes from Bayer MaterialScience AG of Leverkusen, Germany.
The Bayer carbon nanotubes increase durability by a factor of two to three while also decreasing the fatigue that is often seen in traditional boards subjected to everyday conditions, Rey Banatao, one of Entropy's founders, said in a news release. We decided to pursue using carbon nanotubes in our products once they became available and affordable.
A composites laboratory at the University of California at Berkeley tested the epoxy systems in Entropy surfboards.
Bayer supplies multiwalled carbon nanotubes that Amroy uses to create hybrid epoxy matrix adhesives and resins. A proprietary Amroy pre-manufacturing preparation method enables the formation of covalent bonding with the epoxy resin molecules.
Entropy uses the Hybtonite system in wrapping surfboards and believes the material increases toughness without sacrificing the board's flexural properties.
Bayer has operated a pilot carbon-nanotube plant with annual capacity of 132,000 pounds in Laufenburg, Germany, since 2007 and said May 5 that it had begun construction in Leverkusen of a plant with the annual capacity to produce 440,000 pounds of carbon nanotubes.
Our Baytubes are helping create entirely new materials with revolutionary properties for applications like the Entropy surfboard in numerous fields, said Joe Ventura, business development manager at Bayer MaterialScience LLC, the firm's North American office in Pittsburgh.
