In the world of modern manufacturing, standard plastics often fail when the heat is turned up. For industries like aerospace, electronics, and automotive, “standard” isn’t enough. You need materials that maintain structural integrity, chemical resistance, and mechanical strength at extreme temperatures. At Viethung Plastics, we specialize in these high-performance solutions.

What Defines High-Temperature Plastics?

We categorize high-temperature resistant engineering materials as those capable of a continuous working temperature of ≥150°C. Since our establishment in 2015, we have become a trusted “one-stop” provider for these specialized materials, serving global leaders like Samsung and Foxconn.

The PEEK Powerhouse: Strength Meets Heat

Polyetheretherketone (PEEK) is the gold standard for high-temp plastics. It offers an incredible combination of thermal stability and mechanical toughness. Our specialized PEEK range includes:

POM and Acetal: The Precision Engineering Choice

While PEEK handles the extremes, POM (Polyoxymethylene) remains the backbone of precision engineering due to its low friction and high dimensional stability. We offer various grades to suit specific industrial needs:

Fluorine Plastics for Chemical Resilience

For applications requiring both heat resistance and near-total chemical inertness, our Fluorine plastic range is unmatched. This includes Unfilled PTFE, PFA, and PCTFE. These materials are vital for sealing and wear-resistant components in harsh environments.

Why Source from Viethung Plastics?

Located in Vietnam, Viethung Plastics operates as a regular manufacturer, allowing us to offer direct factory pricing without the middleman markup. Our competitive edge is built on:
