February 15, 2025 – Polyplastics Co. has recently unveiled an eco-friendly composite material named PLASTRONⓇ LFT RA627P, marking a significant advancement in sustainable materials technology. This innovative product is a composite of polypropylene (PP) resin and long cellulose fibers, offering a unique combination of low density, high specific stiffness, exceptional impact strength, and superior damping properties. It opens up new possibilities for applications such as audio components and industrial part housings.
The launch of PLASTRONⓇ LFT RA627P underscores Polyplastics’ unwavering commitment to reducing the environmental impact of materials and promoting sustainable development. According to AsiaMB’s industry insights, the incorporation of recycled cellulose fibers in this material results in a carbon footprint reduction of approximately 30% compared to traditional 30% short glass fiber-reinforced PP resin, representing a substantial improvement in environmental performance.
PLASTRONⓇ LFT RA627P is composed of PP resin and 30% long cellulose fibers, all of which are of uniform length and orientation. Thanks to unique spinning conditions and the polymerization technology used for the cellulose raw material, the recycled cellulose fibers endow PLASTRONⓇ LFT RA627P with high strength and elasticity. Moreover, this material boasts a density that is about 10% lower than that of 30% short glass fiber-reinforced PP resin, while maintaining a similar flexural modulus, resulting in higher specific stiffness and a greater loss coefficient.
Remarkably, high specific stiffness and a large loss coefficient are typically inversely related, but PLASTRONⓇ LFT RA627P has successfully achieved an outstanding balance between the two. This unique attribute makes the material highly promising for applications where such a balance is crucial, such as in speaker diaphragms for audio equipment.
Furthermore, Polyplastics is actively developing new grades of materials made from recycled PP resin, aiming to further reduce carbon footprint levels and expand the PLASTRONⓇ LFT product portfolio to meet the growing market demand.
