TOKYO, March 9, 2022 /PRNewswire/ — Polyplastics Group has announced the introduction of PLASTRON(R) LFT (Long Fiber Reinforced Thermoplastic Resins) which are made of specially formulated regenerated cellulose fibers. The environmentally friendly CHEST(R) LFT offers weight reduction and mechanical strength, allowing manufacturers to reduce their carbon footprint and meet today’s sustainability needs.
Environmentally friendly resins that incorporate natural fibers, starch, wood powder and other natural plant and mineral fillers are being considered for use in a wider range of applications. apps. Cellulose is a promising material to help reduce CO2 emissions but its insufficient strength is a limiting factor. Polyplastics solved this problem by using regenerated cellulose in the development of LFT resins with an excellent balance of physical properties. Regenerated cellulose is natural cellulose spun into continuous fibers by wet spinning.
Cellulose being very insoluble in solvents, a large part of regenerated cellulose fibers is manufactured by long and tedious processes. Simplifying these processes would likely lead to a further reduction in CO2 emissions. Polyplastics has developed regenerated long fiber cellulose materials via a solvent method – a simple manufacturing process that emits very little CO2. As this method involves a closed process that recovers virtually 100% of the solvent, it generates virtually no waste and produces even more environmentally friendly materials. The company has obtained several patents for this technology in Japan and internationally.
A comparison of long-fiber cellulose-reinforced PP resin and glass-fiber reinforced PP resin at the same flexural modulus shows that the cellulose-reinforced resin has a lower density than the glass-filled resin. While long fiber cellulose reinforced PP resin has approximately 3% higher flex modulus than 30% glass reinforced PP resin, it exhibits higher values for Charpy impact strength, tensile and flexural strength, indicating potential for improved strength.
