Issue 2 2021 - CNF High Concentration Composite Resin Achieves Plastic Lightweighting Goals

CNF high-concentration composite resin achieves the goal of lightweight plastics

Recently, Japan's Daio Paper Co.
, Ltd.
announced that it has successfully developed a cellulose nanofiber (CNF) composite resin
with a cellulose concentration of 55%.
The CNF high-concentration composite resin "ELLEX-R55" developed by the company has recently started to provide samples
.

It is reported that "ELLEX-R55" can dilute CNF to the concentration
required for performance according to the needs of users for resin molding processing.
For example, even if CNF is diluted to about 10%, its bending characteristics can be improved (CNF is 10%, and its flexural elasticity is 1.
7 times), and the thickness of the material can be reduced
.
Therefore, as the resin material is reduced, the goal of reducing the weight of plastics can also be achieved
.

In the process of developing CNF high-concentration composite resin, Dawang Paper also pays attention to efforts to reduce costs in order to facilitate the commercialization
of CNF.
The company currently provides easy-to-form pellets through the Mishima plant to reduce manufacturing and logistics costs
.
In addition, the company has partnered with Shibaura Machine to develop a pretreatment process for CNF and significantly improve the productivity
of composite resins.
This development project has been adopted
by the New Energy Industry Development Organization (NEDO) project "Development of nanofiber-related technologies contributing to a carbon-recycling society".
Dawang Paper said that it will further accelerate the commercialization process
of CNF.
