Polyplastics Group, an expert in engineering thermoplastics, has developed a solution that transforms high-performance resins into fine powders.
Called DURAST® Powder technology, this solution can turn very strong plastics that normally can’t be made into powder, and engineer them into customized powder forms (smooth, round, or fibrous) so they work in different additive manufacturing processes.
According to the company, high-performance resins like liquid crystal polymer (LCP) and polyphenylene sulfide (PPS) faced challenges with conventional grinding methods, such as particle agglomeration and reduced flowability.
Using Polyplastics’ proprietary technology, DURAST® Powder achieves uniform powderization with an average particle size of approximately 1~100 μm for LCP. This powder exhibits excellent powder flowability and mixing dispersibility, contributing to process stability and improved quality.
When considering the thermal and mechanical properties of these resins and selecting powderization methods suited for each, the technology produces powders with particle sizes ranging from 20μm to 100μm with a narrow particle size distribution.
DURAST® Powder is suitable for additive manufacturing and powder sintering, enabling the production of complex shapes and high-precision parts. Additionally, it is expected to be utilized as a matrix resin for carbon fiber-reinforced thermoplastics and as an organic filler or reinforcing material.
For the record, the company officially debuted in the additive manufacturing industry in 2022, when it developed a 3D printing (Material Extrusion, or MEX) technology for its DURACON® POM resin.
