Comparison of Recalon PA6 66 Nylon and Qunsail POM Acetal rods and sheets for custom wear resistant engineering gears.

Nylon vs. POM (Acetal): Which Is Better for Wear-Resistant Gears?

Leave a Comment / PA, Plastic Parts, POM / By

When engineering high-performance machinery, selecting the right material for non-standard, custom mechanical components is critical. Among engineering plastics, two titans dominate the power transmission landscape: Nylon (Polyamide) and POM (Polyoxymethylene, commonly known as Acetal). Both polymers are renowned for their exceptional wear resistance and self-lubricating properties, but they behave vastly differently under mechanical stress, moisture, …

Custom PTFE spring seals, O-rings, and tubes for high pressure and chemical resistant applications in oil and gas industry.

High-Pressure & Chemical-Resistant Plastic Seals & Tubes for Oil & Gas

Leave a Comment / Plastic Parts, PTFE / By

The oil and gas industry operates under some of the most punishing environments on Earth. From deepwater offshore drilling to high-pressure, high-temperature (HPHT) downstream refining, equipment components are constantly exposed to corrosive fluids, sour gas (H₂S), abrasive chemicals, and extreme mechanical stresses. In these critical applications, standard elastomeric seals and conventional piping materials quickly degrade, …
