Polyoxymethylene is a smooth, shiny hard and dense material,yellowish or white, can be used in the temperature range of -40-100 ° C . Its wear resistance and self-lubrication is superior to most engineeringplastics , and it have good oil resistance, resistance to peroxide performance.It is no acid resistance, alkali resistance and not resistant to solar UV radiation. POM tensile strength 70MPa, small size, water stability, luster, the good performance superior to nylon, POM is a highly crystalline resin, the thermoplastic resin is the most tenacious. With thermal strength,flexural strength, fatigue strength are high, wear resistance and excellent electrical properties.
