How Additives Improve POM Properties?
In POM parts manufacturing, Various additives can be incorporated into POM to enhance its properties:
- Lubricants: Improve wear resistance and reduce friction.
- Reinforcements (such as glass fibers or carbon fibers): Enhance strength and stiffness.
- Impact modifiers: Increase toughness and impact resistance.
- UV stabilizers: Protect against degradation from UV radiation.

Can POM be recycled?
Yes, POM can be recycled. However, the recycling process for POM can be more challenging compared to some other plastics due to its high melting point and resistance to degradation. Recycling POM typically involves mechanical recycling methods, such as shredding and reprocessing, rather than chemical recycling.
What are the types of POM material?
POM materials primarily come in two types: copolymer and homopolymer. Copolymer POM offers better resistance to chemicals, while homopolymer POM provides superior mechanical strength.
Is POM stronger than nylon?
Comparing POM and nylon for strength is context-dependent. While POM generally offers higher stiffness and hardness, nylon tends to have better impact resistance and flexibility.
