POM homoformaldehyde | co formaldehyde, commonly known as saigang, has excellent comprehensive properties and is known as metal plastic. It has high elastic modulus, high hardness and stiffness, and can be used at low temperature of minus 40 degrees to high temperature of about 150 degrees. POM can withstand repeated impact for many times, with good toughness, cracking resistance, fatigue resistance, small creep, good wear and friction resistance, no sound and abnormal noise during friction, small friction coefficient and high strength.
POM plastic uses: auto parts, electromagnetic reversing valve, buckle, car door lock, ball seat, shift lever, rearview mirror, sun shield, accelerator pedal, car handle, water meter shell, faucet shower, children's car accessories, toy gear, bathtub handle, razor switch, zipper, umbrella, washer gasket, bearing sleeve, faucet support, cage, computer keyboard, massage head products, fitness equipment, roller, pulley Bearings, household appliances, floor sweeping robots, hooks, furniture guide rails, hinges, hinges, fax printer gears, washing machines, refrigerator accessories, air conditioning accessories, etc
