The idea :

​

Porous ceramic tips in a flexible rubber matrix

The result :

​

The porous structure gives superior friction preservation in wet and muddy conditions 

It also ensures that the friction is always the same regardless the wear level of the ceramic tip

Other solutions                                 vs                                    CeraGum

Patterned rubber has a short lifetime

The friction of aluminate ceramic drum lagging decrease dangerously with the tips wearing

Dry :        0,60          ↓            0,55          ↓          0,45           ↓          0,40

Wet :       0,40           ↓           0,35           ↓         0,30            ↓         0,25

CeraGum has ±3 times longer lifetime of the best rubber quality

The friction of the CeraGum never decreases

Dry :        0,60          =            0,60          =          0,60          =          0,60

Wet :       0,50           =           0,50           =         0,50           =         0,50
