Acetal Delrin Sheet

Acetal resins (polyoxymethylene or POM) are engineering thermoplastics based on formaldehyde polymerization technology. Acetal resins have high tensile strength, stiffness, resilience, fatigue endurance, a low coefficient of friction against metals, acetals and other plastics and moderate toughness. The Acetal sheet has high resistance to organic solvents, excellent dimensional stability, a low coefficient of friction and outstanding abrasion resistance among thermoplastics.

Acetals’ resistance to creep is excellent. Moisture, lubricants and solvents including gasoline and gasohol have little effect on this property, which is important in parts incorporating self-threading screws or interference fits. Good electrical properties qualify these materials for electrical applications requiring long-term stability. Acetal copolymers retain much of their toughness through a broad temperature range and are among the most creepresistant of the crystalline thermoplastics. A low moisture absorption characteristic permits molded parts to serve reliably in environments involving humidity variations.


POM sheet or poly oxy methylene (POM) is a name of popular plastics which are widely used in the engineering world. POM sheets are also known as acetal, polyacetal, and polyformaldehyde.

POM sheets and plates are counted among stiffest of all thermoplastics. They’re generally produced by different chemical firms with slightly different formulas such as; Ramtal, Delrin, Celcon, Duracon, Kepital, and Host form.

Types of Poly Oxy Methylene

The POM sheets are divided into two types;

  • Homopolymer POM – the process of direct polymerization results in homopolymer. It comprises of higher crystallinity and often results in higher stiffness.
  • Copolymer POM – Copolymer is created when formaldehyde is converted to trioxane. This procedure is totally polymerized together with a co-monomer, to a POM copolymer (e.g. Host shape).

It has high chemical resistance, it regularly brings about less warm debasement while generation, and in the field.

Best features of POM sheets

The best features pf POM sheets are given below;

  • The POM sheet is determined by its hardness, high firmness, high quality, low rubbing, unbending nature to −40 °C, and fantastic dimensional security.
  • Since it has a high crystalline creation, so it looks murky white, but on the other hand, it’s accessible in another assortment of colors. The most extreme thickness of POM is 1.410– 1.420 g/cm3.
  • POM sheet is versatile for its diversified engineering applications. Its function works in CNC machining, and POM sheets are also available with an enhanced bearing grade material.
