Catalog excerpts

MI 00 301 Il Materiale MI 00 301 è molto affidabile, ha una bassa usura resistente alle alte temperature. Risulta molto silenzioso durante l’utilizzo. Composizione del materiale: Il filo in fibra di vetro di rinforzo è avvolto a spirale su un sottile nucleo in rame. Questo da origine ad un materiale resistente con buone proprietà di trasferimento del calore su tutta la superficie. MI 00 301 is very reliable Friction Material, has a low rate and hard wearing. MI 00 301 is very silent during use. Composition:The glass fiber reinforcment yarn is spiral woven with a fine copper core to produce a strong material with good heat transfer characteristics.
