The material comprises essentially very high molecular weight polyethylene having a molecular weight greater than 500,000 and a light transmissivity greater than 10%.
<??>During its manufacture, this material is treated in the hot state (heat-treated) by means of a two-stage heating process towards a controlled fusion state followed by a quenching.
<??>Such a material is ideal for high-speed professional skis owing to its excellent ability to retain wax.
