Break Through Industry Bottlenecks! Baoli Plastic's New Powder Technology Unlocks New Possibilities in Engineering Plastic Manufacturing

Technological Breakthrough: Achieving "Micron-Level Transformation" of Difficult-to- Pulverize Resins

The powdering of high-performance resins has long been recognized as a technical high ground in the industry. For high-strength resins such as LCP (liquid crystal polymer) and PPS (polyphenylene sulfide), traditional crushing methods are prone to issues such as particle entanglement and a sharp decline in flowability. On the other hand, resins like PBT (polybutylene terephthalate) and POM (polyoxymethylene) have low glass transition temperatures, and the frictional heat generated during the crushing process can lead to material agglomeration, making the micronization of high molecular weight grades particularly challenging.

Polyplastics has completely broken this deadlock with its exclusively developed powderization technology. By customizing dedicated processes according to the thermal characteristics and mechanical properties of different resins, it has successfully achieved uniform powderization of various high-performance resins: the average particle size of DURAST® LCP powder can be precisely controlled between 1~100μm, while the particle sizes of PBT and POM powders are stabilized in the range of 20~100μm, with all categories possessing a narrow particle size distribution and regular morphology. This "tailor-made" technological approach not only retains the high performance of the original resins but also endows the powders with excellent flowability and dispersibility, providing a core guarantee for the stability of subsequent processing and the quality of the products.

Performance Upgrade: A Comprehensive Breakthrough from Processing Adaptation to Function Optimization

The core advantage of DURAST® Powder lies in achieving a perfect balance between performance and processability through morphological innovation. Compared to traditional granular materials, this fine powder has made qualitative leaps across multiple dimensions.

In terms of molding uniformity, for resins that are prone to anisotropy, such as LCP in injection molding, powder injection molding can directly produce low-anisotropy products, addressing the long-standing issue of performance inconsistency in the industry. In terms of mixing and dispersion, for multi-component polymer alloys, the granular form can effectively avoid the problems of "low-temperature decomposition and high-temperature unmelt" caused by temperature differences during processing, achieving stable mixing at the processing temperature of the matrix resin.

What is more noteworthy is its controllable morphology—it can be processed into various shapes such as spherical or fibrous according to the purpose. Among them, spherical powder stands out in processes like Selective Laser Sintering (SLS) due to its high sphericity and narrow particle size distribution. For example, modified DURAST® POM powder not only exhibits low warping in SLS molding but also achieves more than 95% model density.

Scene Expansion: An Innovative Application Ecosystem Across Multiple Industries

The processing flexibility brought by powderization allows DURAST® Powder to penetrate application areas that traditional granular materials cannot reach, thereby building an application ecosystem that spans multiple industries.

In the field of additive manufacturing, it is suitable for 3D printing additive forming and powder sintering processes, enabling precise manufacturing of complex shapes and high-precision components, perfectly aligning with the needs of lightweight structural parts in the aerospace sector and customized instruments in the medical industry. In the field of composites, it can serve both as a matrix resin for carbon fiber reinforced thermoplastic (CFRTP) to enhance the mechanical properties of composites, and as an organic filler to optimize the strength and durability of existing materials.

In the field of functional materials, the narrow particle size distribution makes it an ideal raw material for manufacturing filter materials with uniform pore structures. As an additive in thermosetting resins, coatings, and lubricants, it can significantly enhance the heat resistance and stability of products. More importantly, this material has recently gained attention in the research of PFAS alternatives, providing a new direction for material upgrades in the context of tightening global environmental policies.

Industry Value: A Material Revolution Reshaping Manufacturing Logic

The launch of DURAST® Powder essentially reconstructs the logic of engineering plastic manufacturing. It breaks the inherent belief that "high performance inevitably entails processing limitations." Through powder technology, it enables full-process adaptation from prototype design to mass production. For high-end manufacturing enterprises pursuing customization, this material can significantly enhance design freedom and shorten the new product development cycle. For large-scale production scenarios, its stable processing performance can reduce the defect rate and improve production efficiency.
