Acetal, also called POM, can be divided into homopolymer and copolymer. These two materials are crystalline and have great fatigue fracture, creep resistance, low friction coefficient and attractive appearance. Homo polymers have high tensile strength, flexural strength, fatigue resistance and hardness, and copolymers are thermally stable, easy to process, and resistant to heat and degradation.
They are also very alkaline and stretchable. Blue-colored POM (Polyoxymethylene) is often used in the food industry to make products that, in case of breakage, can be easily detected by the naked eye and removed to prevent contamination of the food stream.
Characteristic
-Highly mechanic and strong in terms of heat and electricity
-Highly fatigue-resistant and creep-resistant
-Yields little friction highly wear-resistant and magnetic-lubricating
-Highly resistant to various chemicals (highly alkaline-resistant) heat and water
-Easily processed using machine and yields products of even sizes
-Recommended for areas requiring a high degree of hygiene and sanitation such as food.
