New impact modifier fortifies bioplastics
Rohm and Haas Co. is offering a new impact modifier specifically aimed at bioplastics.
Polylactic acid polymer's use in packaging has been constrained because it is weaker and more brittle than conventional plastics, according to Philadelphia-based Rohm and Haas.
The firm's Paraloid BPM-500 makes bioplastics stronger without sacrificing clarity, which has been a shortcoming of previous modifiers, the company claims.
Paraloid BPM-500 uses dispersible nanoparticles that do not scatter light, the firm said. The additive at 5 percent loading in PLA exhibits less than 10 percent haze. As well, it is food-contact compliant in Europe and the United States.
Mold release made for difficult projects
Chem-Trend LP has debuted a mold-release agent for uses where prerelease is a problem.
The Howell, Mich., firm said its Chemlease CPR is a semipermanent mold release for difficult jobs such as very large parts that are prone to pull away from the mold surface before operators can back the part with glass fiber and resin.
Chem-Trend claims its release doesn't sacrifice cure time or part quality, and provides multiple releases with a Class A finish.

Biodegradable film protects containers
Maverick Enterprises has introduced a biodegradable film designed to protect dishes and containers made of biologically derived materials.
Green Film protects bio-based dishes from degradation when they come into contact with food, as well as humidity and moisture. The film has multiple layers and an adhesive that can be laminated onto dishes by heat or vacuum, or by pressure in molds.
Maverick of Monroe, N.C., claims Green Film is compostable and degradable in landfills.

All-natural colorants made for biopolymers
Clariant Masterbatches has developed a family of all-natural colorants and additives aimed at environmentally friendly polymers gaining ground in ``green'' packaging and consumer goods.
Clariant said the Renol-natur color masterbatches and Cesa-natur additive masterbatches are biogegradable and based on renewable resources. Until their introduction, users of biopolymers had to rely on colorants and additives that don't decompose like the biopolymers. The issue will become more important as the volume of such polymers grows, said Chris Pandis, global head of packaging. Renol-natur and Cesa-natur are derived mainly from plants and rely entirely on sustainable resources, according to the company.
Clariant of Muttenz, Switzerland, said biopolymers such as polylactic acid, polyhydroxyalkanoate and starch-based resins are mainly used in packaging, but producers of cellular phones, personal music players and laptop computers also are very interested in adopting them.
Renol-natur colors including red, orange, yellow, green and blue are available or in development. Clariant plans to sell its new colorant and additive masterbatches globally. It will release more details on the program at K 2007 trade show, slated for Oct. 24-31 in Dusseldorf, Germany.

Pipe Coil introduces low-ovality coilers
The name tells it all: Pipe Coil Technology Ltd.
The British company is touting a breakthrough in its coiling technology for large-diameter high density polyethylene pipes: coiled pipe with little or no ovality. Benefits include elimination of coil failure during storage, no more rejected coils by customers and lower transport costs by making coils with reduced internal diameters, which allows longer coil lengths with the same overall volume, the company said.
The low-ovality coilers are self-contained machines designed to operate at the end of any pipe extrusion line, with no modification to the extrusion process needed.
Pipe Coil Technology is based in Wallsend, England.

GraviPlus feeder aids in quick changeovers
Colortronic North America Inc. of Flint, Mich., has introduced a gravimetric feeder to its GraviPlus line of equipment.
The feeder helps compounders change their lines over quickly, to meet short production runs, various recipes and short-delivery requirements, Colortronic said.
The GraviPlus feeder has a modular design, so a station can be converted from a pellet to a powder additive quickly, and free-flowing ingredients can be added, like titanium dioxide, calcium carbonate and pigments.
Also, the C-Flex M and C-Flex ER flexible walled feeders, and liquid feeders, can be used with the same system.

TSM Control Systems touts batch blender
TSM Control Systems of Alpharetta, Ga., has launched the Opti-Mix batch blender, with throughput ranging from 2-440 pounds an hour.
The Opti-Mix uses four easily removable hoppers, with integrated slide valves for fast material changes. Another feature is patented TSM reverse-flight auger mixing.
As many as 100 preprogrammed recipes can be accessed instantly, according to the company. A new job can be loaded instantly, including blend percentages or job size.
Rapid mold changer made for PU systems
BBG GmbH & Co. KG of Mindelheim, Germany, offers rapid mold-changing systems for polyurethane processing.
BBG uses quick couplings for energy and material supply, and a quick-clamping system for the mix heads. The molds are moved in and out quickly on ball and roller rails.
The company claims molds can be changed in just four minutes with its technology, which uses magnetic molding plates.

Refrigerated air dryer reduces energy costs
Compressor maker Sullair Corp. has developed a refrigerated cycling compressed air dryer that the company claims reduces the cost of drying compressed air.
The SRC-250 to SRC-1000 models use a scroll compressor. Other standard features, on dryer models SRC-400 to SRC-1000, include a zero-loss drain integrated into the heat exchanger to collect condensate.
The SRC-150 through SRC-200 cycling air dryers have simple analog indicators and controls, but models SRC-250 and larger sizes feature programmable, user-friendly microprocessor controls that show the dew point, safety alarms and other functions.
Sullair is based in Michigan City, Mich.

Vecoplan has control for shredding system
Vecoplan LLC, which makes industrial shredders in High Point, N.C., has a new control panel developed with the Allen-Bradley Division of Rockwell Automation Inc.
The controller, called Revision 9A, has a customizable program setting. Benefits include improved communication and control of shredder features, and expanded operator-interface func- tions, the firm said.
Rev. 9A uses the new A-B VersaView CE with Microsoft Windows CE, bringing together the features of the PanelView Plus operator interface with VersaView industrial computers.
Patent granted for lubricated grooves
Jack Lemkin, president of Sinitron Corp., a mold components importer in Columbus, Ohio, has been granted U.S. patent 7,229,265 for mold locks with lubricating grooves. Mold locks are used to maintain precise alignment between the halves of an injection mold.
Separate patent claims include ``X-shaped intersections'' and ``means of introducing lubricants into grooves.''
Sinitron claims the use of lubricants such as Mold-Lub, combined with a boron nitride coating, reduces wear so effectively that the firm warranties its mold locks against wear for one year.
Lemkin claims that using or making a mold that includes mold locks with X-shaped grease grooves could infringe on the patent, which he received June 12.
