PolyOne to Acquire Clariant Color & Additive Masterbatch Business
Early synergies and innovation opportunities are seen by PolyOne in the forthcoming acquisition of Clariant Masterbatches. 

SABIC will encourage sustainability with bio-renewable and recycled feedstocks and designing lightweight packaging.

K 2019 Preview: Resins & Additives for Sustainability in Cars, Electronics & Packaging
Material suppliers are committed to the ‘Circular Economy,’ as evidenced by their adoption of new technologies, product introductions and collaborations.


K 2016 Preview: Materials & Additives
Driving the wide range of new developments in engineered plastics and additives are higher performance, safety, and sustainability.

Clariant's New Rotational Molding Lab Aims For Fast Color Matching
New rotational molding lab at Clariant's Toronto facility caters to North American rotational molding.

Additives at NPE: Many Routes To ‘Greener’ Plastics
Just as eco-friendliness was a major theme in materials news at the big show in April, so it was with additives.

The first polyphosphonate polymers

Polyphosphonate: New Flame-Retardant Cousin of Polycarbonate
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.

Exploring processing of renewable, biodegradable injection molding materials

Injection Molding Biopolymers: How to Process Renewable Resins
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.

Enhancing Biopolymers: Additives Are Needed for Toughness, Heat Resistance & Processability
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.

Clariant and Bayer Partners In Nanotube Compounds
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.

Cryovac’s foamed PLA trays

Foamed PLA Shows Promise In Biodegradable Meat Trays
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.

The first thermoformed trays of PLA foam were introduced in Italy

Biopolymers Strive to Meet Price/Performance Challenge
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.


'As Good as New' Chain Extender Restores Reclaimed Resins
A new additive can re-link polymer chains in reclaimed PET, nylon, and polycarbonate to revive degraded properties.

Edge tear of WPC boards

Wood-Filled Plastics: They Need the Right Additives for Strength, Good Looks, and Long Life
Wood-plastic composites, or WPCs, are already a 1.3-billion-lb market and are growing at 20% annually.

Crystallizing dryer and continuous solid-stating unit

Recycled PET/PE Alloys Show Promise In Monofilament, Pallets, Pipe
Alloys of polyethylene and recycled PET were the highlight of the annual SPE Global Plastics Environmental Conference (GPEC) in Detroit in February.

Foamed films

Foamed Films Find New Niches
Thin polyolefin foams have been made for decades for decorative ribbons, wire wrap, and sleeve-type labels.

Photo-Graftable UV Absorber Gets the Yellow Out
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.

There's Plenty of Fizz In Foam Blow Molding
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.
