Comparative Analysis of POM with Other Plastics:
Some of the key advantages and limitations of POM compared to other plastics are highlighted below:
POM vs Nylon
- POM has lower moisture absorption and better dimensional stability than nylon
- It has higher tensile strength, hardness and modulus than nylon
- Nylon offers higher toughness, ductility and impact strength compared to POM
- Nylon has better chemical resistance than POM, especially to bases, oils and greases
- POM provides lower coefficient of friction than nylon
POM vs Polycarbonate
- POM has much higher strength, hardness and stiffness than polycarbonate
- PC offers very high impact resistance compared to brittle
- POMPolycarbonate has superior temperature resistance up to 140°C vs 90°C for POM
- POM has lower moisture absorption and better dimensional stability
- PC has higher ductility and fracture toughness compared to POM
POM vs Polyimide
- Polyimide can withstand much higher temperatures than POM
- It has excellent strength retention at high temperatures vs POM
- POM offers better impact strength and machinability
- Polyimide has superior wear resistance and chemical resistance
- POM has lower density and moisture absorption compared to polyimide
