Avient launches new long-fiber reinforced nylon 6 and 6/6 composite materials

On July 12, 2021, Avient announced the launch of a new series of nylon-based Complēt™ long-fiber reinforced thermoplastic composite materials with stronger moisture resistance and smooth surface aesthetics. Nylon 6 and 6/6 in these formulations have delayed moisture absorption, which prolongs the effectiveness of their structural properties in humid environments.


These new materials also hope to solve the inconsistent surface appearance of long-fiber reinforced polyamide. These issues have affected people's perceptions of quality in the past. The long glass fiber reinforced Complēt moisture-proof nylon material has a smooth surface with almost no visible fibers, making it suitable for a wide range of consumer applications.

Complēt moisture-proof nylon 6 and 6/6 grades have a variety of fiber loading levels (weight percentages) worldwide, using long glass fibers, long carbon fibers or mixed combinations. This allows these materials to maintain structural properties between standard nylon and specialty nylon when exposed to moisture. Therefore, these materials are ideal choices for metal replacement and lightweight in automotive and power sports applications that encounter different climates or intermittent water contact.

Eric Wollan, General Manager of Long Fiber Technology at Avient, said: “Manufacturers want to quell performance concerns by limiting the hygroscopicity of nylon 6 or 6/6. The only option is special nylon with poor hygroscopicity and higher cost. Avient The new series of long-fiber-reinforced moisture-proof nylon has been improved and has a slower moisture absorption rate. This greatly extends the effectiveness of the structural ability of the parts in a humid environment or short-term immersion, but the price is more economical."

In addition, Complēt nylon grades provide lower shrinkage for applications that require high dimensional stability. And they can be used as a material solution to cope with warpage caused by uneven cooling.
