Just as eco-friendliness was a major theme in materials news at the big show in April, so it was with additives.
Denesting aid for thermoformed and injection molded packaging also helps with mold release and scratch reduction.
WEB EXCLUSIVE: Two new masterbatches from Clariant Additive Masterbatches, Winchester, Va., offer long-lasting barrier to oxygen and carbon dioxide in PET bottles.
A new thermoplastic made by a polycondensation process similar to that used for polycarbonate offers high clarity, inherent flame resistance, and broad potential for copolymerization with PC and alloying with styrenics and polyesters.
U.S. injection molders are still pretty green when it comes to processing the new crop of renewably sourced biopolymers. These biologically derived polymers made from PLA, PHA and starch-based resins are attracting growing market interest as materials with no ties to petrochemical-based thermoplastics.
Plastics are going “green,” but they will need some help to get there. Biodegradable polymers derived from renewable resources are attracting lots of interest and publicity, but that enthusiasm is counterbalanced by persistent questions of availability, cost, performance, and processability. All these issues are inter-related: Increasing demand will lead to more capacity, which will presumably lead to lower prices. But the foundation is market demand, which ultimately depends on whether biopolymers will have the performance properties and processability to compete with existing non-renewable plastics.
To take advantage of the electrical conductivity and mechanical strength afforded by carbon nanotubes (CNT), Bayer MaterialScience AG in Germany (U.S. office in Pittsburgh) and Clariant Masterbatches (U.S. office in Winchester, Va.) signed a long-term cooperation agreement for development, production, and sales of CNT/thermoplastic compounds and masterbatches.
Foamed food trays made of polylactic acid (PLA) resin, the corn-based biopolymer, have a commercial toehold in Europe and are undergoing market tests here.
High expectations for biopolymers— an emerging class of materials derived at least in part from biological activity—are being tempered by the realities of the marketplace.
A new additive can re-link polymer chains in reclaimed PET, nylon, and polycarbonate to revive degraded properties.
Wood-plastic composites, or WPCs, are already a 1.3-billion-lb market and are growing at 20% annually.
Alloys of polyethylene and recycled PET were the highlight of the annual SPE Global Plastics Environmental Conference (GPEC) in Detroit in February.
Thin polyolefin foams have been made for decades for decorative ribbons, wire wrap, and sleeve-type labels.
Sanduvor PR-25, a uv absorber based on new photo-reactive chemistry, was aimed primarily at coatings when it was first launched a couple of years ago. Since then it has made headway in clear plastics, including flexible PVC, polycarbonate, PET, and other engineering thermoplastics.
Foam blow molding technology may be taking its first baby steps in the market, but this child could be jogging before long. After at least 10 years of testing, there is just one commercial application, but a score of packaging and industrial projects are being developed, mostly in Europe.
