PETG used to make temporary prosthetic
Northwest Artificial Limb & Brace Co. of Minneapolis thermoforms copolyester sheet from Cadillac Plastic and Chemical Co. of Troy, Mich., to make cost-effective temporary prosthetics for amputees.
The sheet's clarity allows a medical technician to determine pressure points on the patient so that the prosthetic can be modified to provide a more comfortable fit.
Once the fit is determined, a temporary mold or socket is made.
Eventually, the glycol-modified PET prosthetic also can act as a mold to make a permanent prosthetic, according to Cadillac.

Vectra preferred for medical device
Liquid crystal polymer provides high strength and dimensional control in a long, slender surgical device that is reusable and disposable, supplied by Pilling Weck Inc., based in Dur-ham, N.C.
Centrex Precision Plastics Inc. of Bellefonte, Pa., injection molds the device using Vectra A130 from Hoechst Celanese Corp. of Sum-mit, N.J. The 30 percent glass-filled Vectra beat out a typical polyetherimide because its high flow allows it to fill complex part details in the mold.
Vectra's mold shrinkage is about 90 percent less than PEI. The material also gives a high-quality finish in a water-heated mold rather than requiring an oil-heated mold as does PEI, according to Hoechst Celanese.
Pilling Weck's Hemoclip Eco-System ligation device is a cartridge with a bayonet plug that locks into a steel handle. The device costs about 84 cents, vs. as much as $60 for machined metal, Hoechst said.

Blow molded bottle has window striping
McKechnie Plastic Packaging of Philmont, N.Y., has added window striping to its bottle blow molding capabilities.
The firm can extrude a second, unpigmented material into the side of a bottle to let consumers see how much of the contents is left.
McKechnie said the option adds value and consumer appeal for cosmetic, food, household chemical and other applications.

New Ferro material dissipates static
Ferro Corp.'s new carbon black dispersion for sheet and bulk molding compounds dissipates static charge without creating a spark. The semi-conductive dispersion in polyester resin is a thick, jet-black paste.
Product number 16-88340 provides volume resistivity of 55,000 ohms per square centimeter at carbon levels of 1 percent in polyester panels, claims Ferro's Liquid Coatings and Dispersions Division in Edison, N.J.

Tinted film can show theft during shipping
Specially tinted stretch film helps deter pilferage during shipping, according to Hi-Tech Film Inc. of Kaukauna, Wis.
If a pallet is rewrapped with clear film during transit, the shipper and consignee will be able to tell that the load has been tampered with.
Hi-Tech supplies tinted film in a range of hand-wrap and machine-grade sizes.
It also offers opaque films to conceal contents, and desiccant films to remove moisture from packages stored in damp environments.
