For designers of electronics enclosures, conductive plastics offer the benefit of lighter weight coupled with cost effective injection molding. But for years, using traditional blended plastic pellet materials, the EMI shielding results were often inconsistent at best, leaving many engineers grasping for something better. There is a new single pellet alternative on the market, promising improved EMI shielding consistency, created using tightly controlled conductive material that delivers unparalleled EMI shielding performance and superior processing.
Parker Chomerics has solved the problem of inconsistent EMI shielding effectiveness in single pellet plastic systems with the processing found in PREMIERTM PBT-225, a conductive plastic pellet system with consistent EMI shielding. This novel material was developed by leveraging our materials science expertise in both EMI shielding and injection molding.
More shielding effectiveness, less weight
Metal to plastic conversions not only eliminate 35% of the housing weight (as compared to aluminum), but also provide up to a 65% cost reduction by eliminating secondary operations such as assembly and machining. PBT-225 is a single pellet, polybutylene terephthalate (PBT) based, electrically conductive plastic, making metal to plastic housing conversions not only possible, but usually the best solution for demanding electronics applications.
Why excellent hydrolysis resistance is important
Single pellet technology vs. multi-pellet blends
Traditional multi-pellet cube blends consist of two or more material pellets, mixed at pre-determined ratios. The very nature of mixing separates materials, resulting in variations which can never really be eliminated.
