Polyamide 6 + MoS2 (casted)
P0LYAMIDE 6 + MoS2 (casted) Nylatron GSM
This material contains molybdenum disulfide particles homogeneously dispersed to improve friction and wear properties, impact resistance without losing or fatigue, typical of polyamides unmodified. Recommended for gears, bearings, sprockets and pulleys.
