Dow adds elastomer, plastomer grades
Dow Chemical Co. has expanded its lineup of Versify plastomers and elastomers with eight new grades.
Six new plastomer grades of the propylene-ethylene copolymers include four for flexible packaging. Versify 2000, 2200, 3000 and 3200 provide new combinations of heat-sealability, shrink, optics, modulus and adhesion to polypropylene and polyethylene. The other two plastomers are aimed at uses requiring easier flow such as injection molding and extrusion coating. These two combine toughness, processability and modulus, and complement conventional PP resins.
Versify 2400 elastomer is well-suited to extrusion, calendering and thermoplastic elastomer applications. Dow of Midland, Mich., claims it is readily formulated to provide balanced flexibility, heat resistance, durability and optical properties.
Versify 3401 is particularly suitable for impact modifying PP to make transparent goods by injection molding and thermoforming. It can boost mechanical properties of cast film without any special blending or compounding equipment.
Dow introduced Versify materials in 2004 and says novel catalysts and the firm's Insite polymerization process allow precise control of the polymer's microstructure, and thus its properties.

Basell trumpets new specialty PP resin
Basell Polyolefine GmbH touts enhanced transparency in its new Clyrell RC514L specialty polypropylene resin aimed at form-fill-seal applications.
The Frankfurt, Germany, firm claims the new material can outperform standard PP in clarity, mechanical strength and processing. It also shows excellent stiffness and high output.
Basell said that unlike PET, the PP can be hot filled, pasteurized and microwave heated. It is suited to both multilayer coextrusion and film lamination techniques and can save weight compared with conventional materials, the firm added.

Firm's urethane mix is for diverse usage
New England Urethane Inc. unveiled a nonplasticized urethane blend for diverse applications including films.
Neusoft urethane blend is available in Shore A hardnesses of 50, 50 and 70 in clear or transparent pellets. The North Haven, Conn., company mainly targets the material at medical, consumer and industrial products where a soft touch is required. The blend can be injection molded, extruded and blow molded.
New England Urethane says Neusoft has the beneficial properties of soft rubber and is priced competitively to polymers and thermosets it is designed to replace. Lack of plasticizer should make it even more appealing to processors, according to the company.

Wine, drinking glass combined in bottle
Australia's Hardy Wine Co. Ltd. is marketing a combined plastic wine bottle and drinking glass.
The Shuttle is a single-serve, 5.6-ounce acrylic wine bottle with a fitted lid that serves as a wine glass.
Miriam Leenders, global marketing manager with Adelaide-based Hardy Wine, claims it is the first plastic wine bottle-glass combination, and added that there is strong market potential at event venues.
``The new technology has the potential to redefine how people drink wines, particularly at sporting events, concerts and performances where glassware is not permitted for safety reasons,'' Leenders said.
The tamperproof bottle is opened by a twist-top action, which releases the glass to pour the wine into it.
``Shuttles are easy to store and will keep for 12 months, which is almost double the shelf life of current PET small-format bottles. Its unique design enables customers to be served more quickly and efficiently, which has the potential to optimize staffing and boost overall sales,'' Leenders said.

GLS aims new series at gaskets and seals
GLS Corp. has expanded its offerings of thermoplastic elastomers with a new series aimed at gaskets and seals.
Versaflex CS5000 TPE compounds have exceptionally good resistance to compression set, according to the McHenry, Ill., company. High melt stability and strong tensile and tear strength and heat resistance are other key properties.
The new series contains Shore hardness ranges of 40, 60 and 80, and products variously can be injection molded or extruded. The pellets are easily colored and don't require drying, according to GLS.

Zeon's new material rubberlike in pliancy
Zeon Chemicals LP claims its new thermoplastic elastomer offers rubberlike flexibility.
Zeotherm 100-60B has flexural modulus similar to rubber. Its durometer is 60 Shore A, similar to many rubbers. By contrast, previous Zeotherm compounds had durometers in the 70-90 Shore A hardness range.
Louisville, Ky.-based Zeon said the new material is based on a nylon plastic phase, allowing for overmolding and welding to rigid nylon parts for structures with rigid and flexible sections.

Noveon makes TPU that is fire retardant
Noveon Inc. has a new fire-retardant thermoplastic polyurethane.
Estane ZHF95AT3 was designed to meet industry needs for a high limited-oxygen index and nonhalogenated TPU, according to Cleveland-based Noveon.
The new compound is well-suited to wire and cable jacketing, where it provides flame retardance while maintaining physical properties, ease of processing and aesthetics. It allows manufacturers the option to consider TPU in cable-tray applications that demand the high flame performance characterized by a TPU with a LOI above 35, according to Noveon, a subsidiary of Lubrizol Corp., in Wickliffe, Ohio.
