Product catalog summary
Product Description
The ISI 301 is an asbestos-free friction material based on nitrile rubber, characterized by a flexible compound. It is primarily used for brake bands and pads, which can be directly cured on metal or bonded later. It is not suitable for riveting. The material can be used both dry and in oil, and is available in pads, rolls, and slabs.
Physical and Tribological Properties
The specific weight of the material is 1.90 g/cm³, with a hardness of Shore D 62. The dynamic friction coefficient at 100°C ranges from 0.37 to 0.41 when dry, and from 0.09 to 0.11 when wet. The specific wear after tribological testing is 0.37 cm³/106Kgm.
Thermal Properties
Thermal conductivity at room temperature is between 1.192 and 1.194 W/m°K, and at 100°C, it ranges from 1.65 to 2.05 W/m°K.
Conditions of Use
The operating temperature should be below 250°C, with a maximum temperature of 300°C. The specific pressure should be less than 30 Kg/cm², and the relative speed should be under 20 m/sec.
Graphical Data Summary
The document includes graphs showing the average friction coefficient during wear tests and fade tests at 100°C. The graphs illustrate the changes in friction coefficient and temperature over a series of braking events, highlighting the material's performance under different conditions.
