High Impact
Low-flow, high-viscosity impact grades with notched impact strength 230% higher than Nylon and PBT — for gears, bearings and load-bearing parts.
01 Material Overview
The high-impact series is the most representative POK product line. M630A is low flow and high viscosity with a high molecular weight and outstanding notched impact strength, long used for gears, bearings, pulleys and conveyor components; M730R and M730F push impact resistance further for parts that must absorb energy, such as luggage dampers, sports equipment and helmet components.
Compared with POM, the series keeps high stiffness while offering better toughness, and its wear resistance is three times that of POM. In gears this means lower wear rates and longer service intervals; in slide rails and pulleys it also means noticeably lower running noise.
M710F is an ultra-low-flow grade for extrusion and blow-moulding parisons. Because melt viscosity is high, injection moulding calls for higher injection pressure and melt temperature, and care to avoid excessive shear at the gate.
