The friction coefficient is lower than that of nylon (PA) and polycarbonate (PC), and the self-lubricating property reduces the need for additional lubrication, which is suitable for oil-free environments (such as food machinery).
The water absorption rate is only 0.2% (1.5% for nylon), and it is almost not deformed in a humid environment, which is suitable for precision parts (such as clock gears, optical instrument brackets).
It can be turned, milled, drilled, and laser cut, and a smooth surface (Ra<1.6μm) can be obtained after processing without post-treatment.
Thermoforming temperature range is wide (160-190°C), which is suitable for complex structure molding.
The density is 1.41-1.42 g/cm³ (only 1/2 of aluminum alloy), which can reduce the inertia of moving parts and improve the energy efficiency of equipment.

polyoxymethylene sheet
pom material
White POM sheet is the "steel" of engineering plastics and is irreplaceable in scenarios that require high strength, wear resistance, precision and stability. From micron-level gears to automotive fuel systems, its performance advantages have been verified by decades of industry. In the future, with the advancement of modification technology, POM will expand its application space in emerging fields such as aerospace and new energy.
