Today's KNOWLEDGE Share

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 POM

Polycarbonate 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

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.
