NSP approves BASF TPU for drinking water
BASF''s Elastollan 1190A16 thermoplastic polyurethane (TPU) is now approved under U.S. NSF (National Sanitation Foundation International) Standard 61 for liners in cured-in-place piping (CIPP) for potable-water infrastructure-rehabilitation projects. This standard is a nationally recognized health effects standard for all devices, components, and materials that contact drinking water. "It is estimated that some major cities lose about 50% of their potable water due to leaks," says Luc Lupien, senior market development specialist for BASF''s Elastollan TPU business in North America.
In the CIPP process, a tube made of TPU is laminated with a polyester fabric. The fabric is then impregnated with an epoxy resin, and the saturated pipe is installed into the old pipe. Heat is then introduced to cure the resin in order to affix the replacement tube to the original pipe wall. A complete wash is then done on the new pipe, resulting in a rehabilitated pipe that can last for decades.
BASF introduced its Elastollan LoTac TPU technology for rehabilitating sewer pipes in late 2005. A material with low tackiness is necessary in this application because air pressure is the preferred method to invert the replacement tube to the original pipe. The first potable-water pipe-rehab project in the U.S. will be in Naperville, IL. It will be implemented by Sanexen Environmental Services (Varennes, PQ).
Basell debuts frozen food-grade PP in America
Basell (Hoofddorp, Netherlands) is now producing polypropylene (PP) resin grades that have withstood freezer temperatures down to -40°F (4.4°C). "We are the first [PP] producer in North America to offer grades with this capability and this can open the door to many new applications for frozen-food packaging customers," says Dave McKeeman, Basell''s marketing manager for rigid packaging, North America.
Previously, food-packaging PP grades could only withstand refrigerated temperatures without cracking or breaking on impact. Pro-fax EP390S high-impact PP copolymer (opaque) resin and Clyrell EC140R polyolefin (transparent) resin are now available in North America to producers of injection molded tubs, trays, and cups ranging from 4-ounces to 1.75-quarts (1.65 liters). Both grades can withstand microwave temperatures and are dishwasher safe.
The grades also offer excellent "snap fit" for lids-even at freezer temperatures. Optional tamper-evident breakaway tabs can also be engineered into the lid to produce an additional differentiating feature, according to McKeeman.
Heritage opts for Ecoflex in compostable bag
Ecoflex biodegradable copolyester from BASF is being employed by Heritage Bag (Carrollton, TX) to produce compostable bags for food-waste disposal. Heritage''s BioTuf bags are approved by the Biodegradable Products Institute (New York, NY) and are certified via ASTM D6400-04 for their ability to biodegrade swiftly and safely during municipal or commercial composting. BioTuf bags incorporate calcium carbonate filler called Minapol developed by Heritage Plastics (Picayune, MS).
"The process used to make BioTuf liners requires a polymer with good melt strength and excellent toughness. Thanks to Ecoflex and Minapol technology, we are able to meet these needs with a bag that is environmentally friendly and very competitively priced," says Peter Klaich, director of compostable and biodegradable products at Heritage Bag.
Tech support augmented for Santoprene
Technical support at ExxonMobil Chemical''s (Akron, OH) Santoprene specialty products technical center in Akron, OH has been strengthened with the addition of a new vertical injection molding machine. It will be used to assist customers with insert and overmolding projects using Santoprene thermoplastic elastomers (TPEs). The new machine, with 130 tons clamping force and a rotary table, was selected because it is similar to those most commonly used in industry.
Gary Lawrence, engineering specialist, ExxonMobil Chemical said, "Our customers are becoming increasingly involved in insert molding and two-shot overmolding projects, and in the plastics industry, this type of work is generally undertaken on a vertical rather than a horizontal machine. With new equipment that replicates the industry norm, we have strengthened our technical support to customers worldwide." The vertical injection molding machine reportedly has a fast cycle time, accurate rotary table, and can produce a 7.5-ounce shot size.
