Are all thermoplastic polyolefins created equal?

Thermoplastic polyolefin (TPO) is one of the fastest growing commercial roofing systems on the market. Developed in Europe in the 1970s, TPO was introduced to the U.S. market in the late 1980s and has become the dominant installed roof system in the industry; now used on 53% of commercial roofs, according to the American Institute of Architects.

Electrically conductive elastomers based on NR and polyaniline

Natural rubber is an electrically insulating material, but introduction of conductive fillers like carbon based materials (carbon black, graphite, carbon nanofibers or nanotubes) or metal fillers can increase the conductivity of the resulting composite. These materials are frequently used for electromagnetic/radiofrequency interference (EMI/RFI) shielding, and laboratory and military uses.

NCSU researchers demonstrate printing electronic circuits on latex

Researchers from North Carolina State University have demonstrated a new technique for directly printing electronic circuits onto curved and corrugated surfaces. The work paves the way for a variety of new soft electronic technologies, and researchers have used the technique to create prototype “smart” contact lenses, pressure-sensitive latex gloves, and transparent electrodes.

APR recognizes OnColor NIR sortable colorants from Avient as preferred for recyclability

Avient Corporation announced its line of near-infrared (NIR) sortable dark colorants was recently recognized by the Association of Plastics Recyclers (APR) under its Meets Preferred Guidance (MPG) program. With the recognition, OnColor™ NIR Sortable Colorants are preferred for high-density polyethylene (HDPE) resin in black and dark colors, according to the APR Design® Guide for Plastics Recyclability. In addition, testing is underway to support an application for MPG recognition for the same colorants for polypropylene resin (PP).
