Leistritz testing dryer-less PET sheet extrusion

March 17 (plasticstoday) -- Extrusion machinery supplier Leistritz has set up two of its MAXX twin-screw extrusion systems, and related auxiliary equipment, in its Somerville, NJ lab to process undried PET and directly extrude it in sheet form. Leistritz says only that the result is a quality product with "dramatically less energy consumption."

In most production environments, PET resin typically is dried separately before being processed on a single-screw extruder. The ZSE-27 and ZSE-50 extruders that are being fed undried PET pellets or regrind have multi-stage vacuum venting to minimize or avoid hydrolysis. The extruders have a gear pump, screen changer, and flexible-lip sheet die attached, which feeds the 3-roll stack that cools and forms the PET sheet.

Leistritz says the ZSE-MAXX series, with increased torque capabilities and a 1:66 OD/ID ratio, is especially well suited to PET processes that are torque-, heat-, and shear-sensitive. The series also has an improved barrel cooling design that benefits PET processing.

Vistamaxx PP-based elastomers add value to flexible films

March 17 (adsalecprj.com) -- The new grades of Vistamaxx propylene-based elastomers offered by petrochemical company ExxonMobil Chemical has created new opportunities for customers to add value to their flexible film applications across the value chain. Film manufacturers and end users are discovering that the combination of benefits offered by Vistamaxx provides a new level of performance potential.

Enhanced sealability, improved adhesion, inherent elasticity, notable toughness and broad polyolefin compatibility delivered by Vistamaxx are inspiring innovation and product development in a wide range of flexible film applications. These include cast polypropylene (cPP), stretch hood, PP raffia tape, extrusion coated and laminated woven and nonwoven polyolefinic substrates, surface protection, cast stretch, and elastic hygiene film. High transparency film applications also benefit from the good optical properties and chemical resistance of Vistamaxx.

The complete combination of benefits allows film manufacturers and end user customers to design films with new levels of performance, lower formulation and processing costs, and achieve sustainability objectives with lower energy usage, reduced material consumption and, as Vistamaxx is a polyolefin, recyclability.

Now four new grades, Vistamaxx 6202FL, Vistamaxx 6102FL, Vistamaxx 3980FL and Vistamaxx 3020FL, have recently been introduced for high performance film applications. The FL series of Vistamaxx grades exhibits a low gel count, provides processing and performance improvements, and protects your investment in film aesthetics, offering film formulators, converters and end-users inspiring new options for next generation film designs. These options include: excellent sealing operation and package integrity; improved film tear resistance at high stretch ratios; and, improvements in scratch and indent-free surface protection.

This series of Vistamaxx FL low gel grades can result in outstanding printing and optical quality and, as with all Vistamaxx grades offered to the film market, complies with the US Food and Drug Administration (FDA) and European Union (EU)-Directive for use in contact with food.

Egyptian PVC producer maintains offer levels

March 17 (plastemart) -- A source from the local PVC producer EPC reported that the producer elected to maintain their offer levels for PVC k67-68 for the rest of the month at EGP5600/ton (US$1022) on ex-Alexandria, cash not including VAT basis, as per Chemorbis. This decision has been compelled by the demand situation as buying interest has not been performing well for the past few weeks. ⌠We preferred to leave our offer levels equal to the cost of material that was imported earlier and is now entering the market, he further clarifies. However, market participants were mainly expecting increases, pointing out that the producer had concluded good sales both in the local and export markets. Plus, the overall import market level was standing at an adjusted range of US$1015-1070/ton on CIF Alexandria, cash equivalent basis last week, showing that the local producer could also find ground from the import market to raise their prices.

INEOS ChlorVinyls announces caustic soda price increase

March 16 (yourpetrochemicalnews) -- INEOS ChlorVinyls has today announced a price increase of Euro 60 per dry metric tonne on Quarter Two 2010 caustic soda contracts.

This increase is necessary due to reduced margins on the electro-chemical unit and the shortage of caustic soda availability as the maintenance season begins. Domestic demand for caustic soda continues to increase across Europe and each of the INEOS Chlor caustic soda producing sites will have planned maintenance outages during the next three months.

The new prices are effective for contract business from 1st April 2010; for new or non-contract business they are effective immediately.
