| 摘要 |
A high performance ski base material is made of ultra high molecular weight polyethylene having a molecular weight of at least 500,000. After heating, quenching and light tensioning operations, this material exhibits low crystallinity and high transparency characteristics. Such material is ideal for professional high speed skis because of its excellent wax retention quality. The invented ski base material is ideally suited for product-identity purposes because of its outstanding ability to clearly reveal detailed inscriptions placed on the running surface of a ski board.
