Mastering color
Colorants change a plastic part's color but may also modify polymer chemistry, physical properties, manufacturability, and cost. Edited by Jean M. Hoffman A new Splash masterbatch formulation imitates marble, wood, tortoise shell, and other materials in base resins such as polystyrene

MICRO: New Materials Integration
of the research described in this article was to quantify the impact of potential error sources and to develop an operating procedure designed to mitigate the most significant ones. Participants at six sites (representing four different companies) analyzed both silica and polystyrene standards using one type

or four macroscratches per wafer. The chopstick-shaped particle defects tended to be captured by only one channel, while the slurry agglomerations, which resemble polystyrene latex spheres, tended to be captured by both channels. For the multichannel bins 72, 82, and 92, the SEM review results

Monitoring slurry stability to reduce process variability
distributions for the same slurry. There are three major factors that contribute to these differences: (1) the various commercially available instruments use different physical principles to measure particle size; (2) slurry particles are irregularly shaped, in contrast to the polystyrene spheres used

Better Injection Molding Through Bubbles
with material choice. Because MuCell cuts melt viscosity and reduces warpage, designers may be able to substitute a lower-grade material for a higher-grade one. Designers of electrical connectors have been able to replace solid-molded syndiotactic polystyrene (SPS) or liquid crystalline polymer (LCP
