Modern ski and board bases must satisfy the following demands: They should be elastic and at the same time they should withstand the highest possible loads. For this reason, sintered bases are predominantly employed in racing today. Sintered bases can be produced with a wide range of different additives, each base form offers
special qualities for particular conditions.

Transparent sintered bases
This base type is characterised by greater toughness, but nevertheless without any
reduced wax absorption ability.

Graphite bases
Graphite protects the base against impurities thanks to its anti-static properties. With
their good thermal conductivity, graphite bases provide good glide properties particularly
in wet snow.

Multi-sinter bases
(different molecular weights of the individual components)
Multi-sinter bases have outstanding all-round properties and they are suitable for
cross country and downhill skis as well as for snow boards since they exhibit good
glide properties in all temperature ranges.

Base structures

The structure of the ski base (the contact surface between the ski and snow) has impact on the gliding character of the ski. Due to this gliding process friction is caused by the snow crystals and suction by the water, contained in the snow. Special structures reduce these effects or even eliminate them. Base structures are produced by stone grind machines. Stone grinds are offered by the qualified specialized trade.

Linear structure	M- structure	KV- structure

Generally valid:
Cold snow/ new snow: fine structure
Old snow/ man made snow/ moist snow: middle structure
Wet/ coarse snow: coarse structure
