| Material | POM | PP | PA | PE |
| Density | 1.42 g/cm³（heaviest） | 1.13–1.14 g/cm³ | PA66:1.13–1.16 g/cm³ | high density:0.94–0.97g/cm³ |
| Mechanical strength | High rigidity, high wear resistance | Medium strength, high toughness | Very high tensile, stiffness, load capacity | Low tensile & rigidity; flexible |
| Working temperature | ﹣40°-80°C（High temperature releases odors） | ﹣0℃-100℃ (brittle at low temperatures) | Standard PA: -45 ~ +120°C
PA-HT (high temp): -30 ~ +155°C
Short peak up to 180°C | -70 ~ +65℃
Extreme cold resistant
Extreme cold resistant |
| Chemical properties | Not tolerant of strong acids | Strong (acid and alkali resistant, solvent resistant) | Resists oils, greases, solvents
Weak vs strong acid/chlorine | Great vs acids, alkalis, most cleaners
Poor vs hydrocarbon oils |
| Application | Heavy-duty conveying, precise transmission (automobile assembly line, logistics transportation (high wear + precision) choose POM) | Food processing, corrosive environment. For food factory baking lines (high temperature + hygiene),The selection of PP for non-frozen food transportation is cheaper than PE. | High temperatures, oily environments, heavy loads and high-intensity wear conditions: automotive parts, mechanical hardware/grain and oil, oil and fat processing, and electronic injection moulding industries, etc. | Suitable for low temperatures, it is primarily used in the frozen food and cold chain industry, as well as in fresh fruit and vegetable processing and seafood processing lines. |
