Unleashing Manufacturing Potential with DURAST® Powder

Polyplastics Co., Ltd., based in Minato-ku, Tokyo, recently unveiled a revolutionary polymer processing technique on their official site, showcasing the potential of high-performance resins in powder form. This cutting-edge material, known as DURAST® Powder, marks a significant advancement in the production capabilities for high-strength and high-molecular-weight polymers. With its unique ability to create spherical or fibrous shapes tailored to specific applications, DURAST® Powder addresses longstanding challenges in traditional powder processing.

Overcoming Conventional Challenges in Polymer Processing

Historically, the powderization of high-performance resins like LCP (Liquid Crystal Polymer) and PPS (Polyphenylene Sulfide) has faced significant obstacles. Traditional grinding methods often result in entanglement of particles that diminishes their flowability, leading to difficulties in processing and final product quality. Polyplastics has overcome these challenges with proprietary technology that achieves uniform powderization with an average particle size of 1 to 100 μm for LCP, enhancing fluidity and dispersion.

Applications Across Diverse Industries

DURAST® Powder is specially designed for various industrial applications, particularly in additive manufacturing through 3D printing and powder sintering techniques. These processes allow for the creation of complex geometries and highly precise components. Additionally, this powder serves as a matrix resin for CFRTP (Carbon Fiber Reinforced Thermoplastics) and can be applied as an organic filler or reinforcement material, opening new opportunities across multiple sectors.

In polymer alloys, challenges arise from differing processing temperatures of thermoplastic resins, which can lead to decomposition of the lower heat-resistant resin or incomplete dissolution of the higher heat-resistant resin. However, starting with a material that possesses defined particle shapes enables stable mixing and dispersion at the processing temperature of the matrix resin.

DURAST® Powder also finds utility as an additive in thermosetting resins, varnishes, paints, and greases. Recently, investigations have begun into its potential as a substitute for PFAS materials, indicating its versatility in various applications. Its narrow particle size distribution makes it ideal for producing porous filters via powder sintering, resulting in uniform pore structures.

Furthermore, using powder for pressing can yield low-anisotropy molded products even with resins like LCP that typically exhibit anisotropic characteristics when injected. This transformation in processing techniques can lead to improved product consistency and reliability.

Future Prospects

DURAST® Powder is set to redefine the landscape of product development and technological endeavors across industries. Companies are encouraged to reach out for prototype creation, collaborative development, and technical consultations to explore how DURAST® Powder can offer novel solutions to existing challenges.
