Royal DSM says that a special lubricated grade of its Stanyl polyamide 46 has been chosen for low-friction slide shoes within the timing system on a new generation of energy-efficient turbocharged petrol engines. The company says that polyamide PA46 is already used in engine components as it’s able to withstand high temperatures, high loads, high velocities, harsh chemical environment and heavy vibrations.
DSM says it has now developed a grade with even better friction performance, Stanyl TW371, which it claims tests have shown a 20% reduction in friction.
