PA/CNF composite materials
(under development)
Light-weight and excellent reworkability* PA/CNF composite material
Our unique nanocomposite materials are composites of highly heat-resistant cellulose nanofiber (CNF) and various polyamide resins. The materials excel in rigidity, dimensional stability, as well as sliding properties, and are expected to be applied to various sliding parts.
*As defined by UL 746A, regrind refers to a noncontaminated product or scrap from molding, such as sprues or runners that have been reclaimed by shredding, repalletizing, and granulating for use in-house.
CNF nanocomposite material composited with various polyamides has excellent rigidity, dimensional stability, and sliding property. It contributes to downsizing, thinning, and weight reduction of sliding parts in all parts of automobiles.

High heat resistance and mechanical properties retention after using regrind
Asahi Kasei’s heat-resistant CNFs exhibit relatively low thermal degradation, fiber rupture and high mechanical properties retention after using regrind. The CNF is highly heat-resistant, enabling itself to be combined with various polyamides such as PA6 and PA66.
High rigidity and dimensional stability
Polyamide CNF nanocomposite materials, which are based on our original CNF dispersion technology, have high rigidity. In addition, our CNF materials enable high modulus and low thermal expansion from low to high temperature.
Sliding characteristics
The CNF nanocomposite materials which are composites of CNF and polyamide achieve low friction coefficients, low wear, as well as low deflection, and have a feature that they do not easily wear objects which can be abraded (metals, etc.).
Increase the biomass raw material ratio
PA610 is a biomass engineering plastic containing polymers that are 60% plant-derived. Blending PA610 with 10% CNF reinforcers yields a composite with 65% plant-derived content. By using PA610 as the base polymer, the biomass raw material ratio is further increased, while still possessing the excellent reworkability, rigidity, dimensional stability, and sliding properties of PA/CNF as explained above.
Downsizing and light-weighting sliding parts
A nanocomposite of polyamide resin and CNF achieves rigidity which is far higher than that of non-reinforced polyamide, contributing to the downsizing, thinning, and weight reduction of sliding parts. Compared with glass fiber reinforced materials, CNF nanocomposite materials may enable the omission of special surface treatment processes for metals because the materials do not abrade the metals on which sliding occurs.
