LyondellBasell offers several new resins
Resin supplier LyondellBasell Industries AF SCA of Rotterdam, Netherlands, has announced a series of new materials.
* LyondellBasell has launched a family of butene-1 based polymers for elastic applications. Koattro resins are aimed at film, fiber, tapes, closure lines and aesthetic injection molding. They are highly compatible with polypropylene and improve that polymer's flexibility, transparency, impact resistance, tensile properties and stress-whitening tendencies.
The company combines softness at Shore A 70 hardness rating and a compression set of 45 percent that is nearly constant up to the melting temperature of 237°F.
Koattro plastomers are easier to regrind and recycle than conventional cross-linked plastomers, according to LyondellBasell. Automotive uses also are possible in areas such as dashboards, wire and cable and heat-resistant skins. Reduced stress whitening makes parts produced from the resins easier to install.

* The company has introduced a high density polyethylene especially well-suited to blow molded bottles.
Hostalen ACP 5231D provides a combination of optimized density, tailor-made stiffness, high environmental stress crack resistance and easy processability.
The firm claims the resin's ESCR is up to three times greater than a typical HDPE with the same density. LyondellBasell achieves high ESCR by a customized, multimodal molecular weigh distribution in its advanced cascade process.

* LyondellBasell has introduced a low-melt-flow rate propylene-based copolymer for extrusion blow molding.
Pristene RM2091 has a melt-flow rate of 3.5 grams per 10 minutes. It also has high transparency with only 2 percent haze in an injection molded plaque vs. 6-10 percent haze for previous resins. It also provides high clarity to stiffness balance, according to the firm's global metocene business unit in Wilmington, Del.
RM2091's high-melt stability makes it suited for applications requiring intricate design such as clear handles in extrusion-molded bottles. Its high clarity and stiffness make it a potential replacement for amorphous transparent polymers including polycarbonate, vinyl and glycol-modified PET. LyondellBasell said the new material does not require pre-drying or high processing temperatures.

Croda UV absorber aids transparency
Croda Polymer Additives has launched a new type of inorganic ultraviolet absorber.
The Goole, England, company says its Solasorb series delivers high UV protection and improved transparency compared to conventional nano-powders.
Solasorb is based on ultrafine metal oxides that allow greater dispersion and clarity. Unlike conventional organic UV absorbers, the new Croda materials have low migration and long-term UV protection. Croda makes Solasorb using patented technology.
Croda is aiming Solasorb at clear film and bottle applications. Such packaging can protect against the harmful effects of UV light, improving shelf appeal and protecting nutritional values. The product is available in a fully dispersed liquid form or in a polymer carrier suitable for polyethylene and polypropylene.

Worthen's UV curing replaces oven drying
Worthen Industries Inc. has debuted an all-solids ultraviolet-cured coating for use on thermoplastic polyolefins and other durable plastics.
SZ-0760 has very low gloss and adheres well to TPO, PVC, polyvinyl butyrate and most elastomers. The clear coating is suited to auto dashboards, composite resilient flooring, furniture and other end uses.
Worthen of Nashua, N.H., says UV cure takes place in minutes and eliminates an oven-drying process and its hazards of volatile organic compounds and fire.

Concentrate boasts wood-grain effects
Americhem Inc. has debuted a concentrate that produces lasting, realistic wood-grain effects.
The Cuyahoga Falls, Ohio, firm says nGrainT builds wood-grain effects directly into the formulation rather than just on the surface as in the cases of embossing and laminated film. The product will not delaminate, crack or be nicked, Americhem claims. Random grain effects help make the product look real. The formulation can be adjusted to give a range of wood-like effects such as bold grains to subtle feathering.
nGrainT can be used in monoextruded, coextruded and foamed products such as siding, cladding, fencing and injection molded accessories like fence-post caps. It is effective in several resin systems, including ABS, polyethylene, vinyl and polystyrene. It also is suited to wood composites with PE, polypropylene and vinyl.

Teknor Color Co. has introduced concentratres for copolyester thermoplastic elastomers.
The new series is compliant with Europe's Restriction of Hazardous Substances Directive. Products are for engineering grade end-uses and come in a range of colors, said the Pawtucket, R.I., company.
The TPEs contain no heavy metals but provide the same intensity and coloring efficiency as conventional colors in engineering TPEs. The concentrates were specially developed for materials like DuPont's Hytrel. Potential applications include wire and cable insulation, injection and blow molded parts, film, sheet and profiles.

PolyOne materials are phthalate-free
PolyOne Corp. has developed PVC masterbatches that don't contain phthalates.
The Avon Lake, Ohio, company said the new products are a good choice for toys, packaging, medical devices and consumer goods that must meet stringent international standards. They can be injection molded, extruded and extrusion blow molded.
PolyOne said it will customize the color for the new materials, assisted by a color and additives center in Assesse, Belgium.

Bayer medical line offers array of colors
Bayer MaterialScience LLC has developed a new range of colors for medical applications.
The Rx Medical line, which is based on Leda-compounding color technology, is compliant with the biocompatibility standard of ISO 10993-1. The line allows new color choices beyond the beige and white chosen for most medical applications.
The new family includes four Makrolon polycarbonate resins that can be used for drug-delivery devices and components of surgical instruments, said the Pittsburgh firm.
The main Rx Medical colors are Electro, medium blue tempered with gray; First Aid, a light brown dabbling in gray; Stat, a red/purple/gray hybrid, and X-Ray, white tinted with a hint of gray.
