Polyplastics Group, an engineering thermoplastics firm, has launched DURAST Powder expertise, which transforms high-performance resins into positive powders, enabling using numerous manufacturing processes from prototyping to 3D printing and mass manufacturing.
DURAST Powder expertise efficiently micronizes high-strength, high-molecular-weight resins – which have been beforehand tough to powder – into numerous shapes equivalent to spherical or fibrous varieties based mostly on software necessities. Specifically, high-performance resins like liquid crystal polymer (LCP) and polyphenylene sulfide (PPS) confronted challenges with typical grinding strategies, equivalent to particle agglomeration and lowered flowability. Utilizing Polyplastics’ proprietary expertise, DURAST Powder achieves uniform powderization with a mean particle measurement of roughly 1~100 μm for LCP. This powder reveals glorious powder flowability and mixing dispersibility, contributing to course of stability and improved high quality.
Resins equivalent to polybutylene terephthalate (PBT) and polyacetal (POM) pose vital challenges when it comes to micronization as a result of their low glass transition when processed through typical grinding strategies. Within the case of PBT and POM, the glass transition temperature (the temperature above which resin softens) is low, inflicting the fabric to simply agglomerate as a result of friction warmth throughout grinding. The brand new method has efficiently enabled the powderization of those high-molecular-weight resins. When contemplating the thermal and mechanical properties of those resins and deciding on powderization strategies fitted to every, the expertise produces powders with particle sizes starting from 20μm to 100μm with a slender particle measurement distribution.
DURAST Powder is appropriate for additive manufacturing utilizing sintering, enabling the manufacturing of complicated shapes and high-precision elements. Moreover, it’s anticipated to be utilized as a matrix resin for carbon fiber-reinforced thermoplastics and as an natural filler or reinforcing materials.
