Sintered

A sintered base on a ski is created by compressing, under heat, hundreds of thousands of tiny balls of base material. Because the material is not melted, the chemical composition of the base material remains unchanged. This results in a harder, more durable and porous base that allows wax to be easily absorbed. The increased porosity of a sintered base means it can be more work to get clean, but the payoff is in longer lasting wax jobs. Sintered bases are also much faster than traditional ski bases, which consist of melted polyethylene plastic that is poured into a mold.
