Features of POM plastic:
More scientific names for this material are polyformaldehyde or polyacetal. This plastic is interesting for high rigidity and stability. It retains its strength at temperatures up to 120 ° C. It is also resistant to impact loads, friction, various types of organic solvents and oils. This material can easily be primed, grinded, painted. Due to its strength POM plastic can be used to replace metal alloys in various functional systems. It is often used to create a variety of gears, sliding elements, bearings, electrical parts and other. In addition, recently due to environmental friendliness this plastic has been used in medicine and in the creation of food equipment. The material’s resistance to sterilization and disinfection contributes significantly to this. Among medical applications, mention should be made of the use of polyacetal in the field of orthodontics.
Plastic POM withstands temperatures from -60 ° C to + 130 ° C, which exceeds the temperature range of most polymers. Along with excellent wear resistance, the material is resistant to various weather conditions.
