avient-composites-new Avient announces availability of a new series of nylon-based Complēt™ long fiber reinforced thermoplastic composites with enhanced moisture resistance and smooth surface aesthetics. These formulations feature nylon 6 and 6/6 with delayed moisture absorption, which prolongs the effectiveness of their structural performance in moisture-rich environments.

Tackling Surface Appearance Issues

These new materials also take aim at inconsistent surface appearance issues with long fiber polyamides, which have affected quality perceptions in the past. Long glass fiber reinforced grades of Complēt moisture-resistant nylon feature surfaces that are smooth and virtually free of visible fiber, making it suitable for a wide range of consumer applications.

Complēt moisture-resistant nylon 6 and 6/6 grades are globally available in several fiber loading levels (weight percentages) using long glass fiber, long carbon fiber, or hybrid combinations. This allows the materials to retain structural properties that fall between those of standard and specialty nylons when exposed to moisture. As a result, the materials are ideal for metal replacement and lightweighting initiatives in automotive and powersports applications that encounter varying climates or intermittent exposure to water.

Enhanced Structural Capabilities of Parts

“When manufacturers wanted to quell performance concerns by limiting moisture absorption for nylon 6 or 6/6, the only options were less hygroscopic and more costly specialty nylons,” said Eric Wollan, general manager of Avient’s long fiber technologies. “Avient’s new line of moisture-resistant nylon LFTs are modified to absorb moisture more slowly. This significantly prolongs the effectiveness of a part’s structural capabilities in humid environments or during short-term water immersion, but at a more economical price point.”

Additionally, Complēt nylon grades provide lower shrink for applications that require high dimensional stability. In effect, they serve as a material solution to combat warp distortion from uneven cooling.
