Nanoparticle boosts Alok UV stabilizer
Alok Masterbatches Ltd. has developed ultraviolet-light stabilizer systems using a nanoparticle synergist.
The New Delhi firm claims the synergist boosts UV protection by 20 percent compared with masterbatches based on hindered amine-light stabilizers and UVA absorbers. Success in polyethylene and polypropylene resin applications has spurred Alok to explore similar systems for engineering resins.
Alok also has developed Addnox, an additive that improves mechanical properties. In PE film and recycled PE the additive improves tear strength while allowing downgauging.

Bayer's Leda creates special color effects
Bayer MaterialScience LLC has developed a range of metal flake-based special color effects in its Leda compounds technology.
Aster Area 51 is a dark metallic that morphs with changing sight lines into flashes of greens, golds and purples. Cadet is a lustrous gunmetal pigment with a cold blue edge. Iguana is a green that verges on the edge of gray.
Leda is one of five color compound technologies Bayer offers as part of its Fantasia color line.
The Pittsburgh-based company has designed several other new colors to keep up with industry trends.
The new effects and colors are especially suited to polycarbonate. Bayer MaterialScience said it can help users with desired special effects at its new design center in Newark, N.J.

PLA masterbatches offer impact strength
Plastics Color Corp. has a new line of masterbatches for polylactic acid using a new impact modifier from Rohm and Haas Co.
Plastics Color said its masterbatch with Paraloid-BPM 500T broadens the usefulness of PLA by making it stronger without losing desired clarity. By incorporating the additive in a masterbatch, the Calumet City, Ill., firm makes it easy to use. Plastics Color said the masterbatch complies with food-contact requirements in Europe and with room-temperature food contact in the United States.

Dow releases TPU for calendering uses
Dow Chemical Co. is introducing a new calendering grade of thermoplastic polyurethane.
The new Pellethanet-brand grade offers performance and processing benefits for fabric and nonwoven applications and for industrial goods such as conveyor belts and sewer lines. The Midland, Mich., firm claims the material has high adhesion and chemical resistance. Dow said it developed the material to address market needs for high-quality elastomers for calendering.
The product is part of Dow's Pellethane TPUs, which also can be processed via injection molding, extrusion and blow molding.

Injection molding PET features LGFR grades
TechnoCompound GmbH is launching a line of injection moldable PET compounds.
The Bad Sobernheim, Germany, firm claims its new products provide fast crystallization rates for short cycle times. Long-glass-fiber-reinforced grades feature improved adhesion between the fibers and polymer matrix for better shear strength.
TechnoCompound said demand for injection moldable PET is growing about 6 percent a year.

Metocene PP targets thin-wall containers
Basell Polyolefins is launching a new metallocene-based Metocene polypropylene for thin-wall injection molded containers.
Clyrell EM248U is a copolymer targeted for U.S. usage, following the European introduction of a similar grade. The PP achieves clarity and impact strength without the addition of plastomers, thus saving costs and an extra processing step, said the Hoofddorp, Netherlands, firm.
Basell claims the new PP has low levels of volatiles and oligomers and does not require viscosity breaking or peroxide treatment. Its low taste makes it suited to food packaging and it can be used with in-mold labeling and offset printing. Its melt flow rate, of about 2½ ounces per 10 minutes, provides processing ease.
