Definition

Polyoxymethylenes are commercially available engineering thermoplastics used in precision parts requiring high mechanical strength, stiffness, toughness in the wide range of temperature and environment.

POM (Polyoxymethylenes)

Polyoxymethylenes (POM) (Eq. 1), sometimes called acetal polymer or acetal resins, are highly crystalline thermoplastic materials exhibiting a broad array of useful properties including high mechanical strength, stiffness, and toughness in the wide range of temperature and environment [1–5]. In many practical applications, POM have replaced metals in a variety of precision parts because of balanced properties as engineering plastics. POM are the first commercial engineering plastic, and they still play an important role in our life. A huge amount of POM is currently manufactured by many companies, and further new high-performance POM are developed.
