Hot-runner engineering firm Eurotool Inc. has entered its Navigator software on the Inter-net at http://www.eurotoolcom, the Georgetown, Ontario, company recently announced. Navigator guides users through the injection molding application and provides detailed information about the hot-runner system layout. Data includes melt channel sizes, melt pressure drop, shear rates along the melt path and residence time.
Eurotool said its technology can handle parts as small as 1 gram or less and as large as an auto bumper.

Mobil's LDPE offers uniform cell structure
Mobil Polymers said its new low density polyethylene for foam applications allows optimum bubble size and uniform cell structure.
Mobil's LFA-003 has a balanced melt index to melt tension ratio that makes it suited to processing of foam liners for bottle caps and PE packaging foam.
It is additive-free, has a 2.2 melt index and its density is 0.918 grams per cubic centimeter, according to the Edison, N.J., company.

PU coating on course for ship's golf project
Royal Caribbean Cruise Lines is installing a golf course on its ``Legends of the Seas'' ship this spring.
Foam Tech/Symmetry Products of Lincoln, R.I., is pre-building the major elements of the golf course in its 100,000-square-foot facility. It includes expanded polystyrene features such as a waterfall, landscaping, bridges and buildings, all coated with polyurethane to add strength and weather resistance. Connect-ing each tee is a walkway made of sprayed in-mold structural PU ``cobblestones'' designed to withstand heavy traffic.
Futura Coatings Inc. of St. Louis supplies the PU coating and structural PU for this project.

Gentek introduces composite siding
Gentek Building Products Inc. recently introduced vinyl/aluminum composite siding for the construction industry.
Vin-Al-Tek siding combines the structural integrity of an aluminum core fused with a high-performance vinyl finish on the front and a vinyl coating on the back.
The firm applied for a patent on the product, which it makes in Woodbridge, N.J., using proprietary technology. Gentek, based in Cleveland, also introduced Vin-Al-Tek trim coil and soffit.

Thermoplastic usurps epoxy potting method
Pacific Scientific eliminated parts, simplified assembly and cut production time when it replaced epoxy potting resins with a thermoplastic polyester in electric motor stators.
The Rockford, Ill., firm encapsulates stators in a single injection molding step using Rynite PET from DuPont Engineering Polymers of Wilmington, Del. Pacific encapsulates stators in a molding cycle of about 45 seconds. The previous epoxy potting method took about two hours including curing cycles in ovens.

Vinyl alloy touted in outdoor applications
Gitto/Global Corp. reports one of its Excelprene vinyl alloys has received UL 62 approval for wire insulation applications.
The Lunenburg, Mass., company said its GTPE-2203 alloy is suited for harsh outdoor use because it is oil-resistant and remains flexible without cracking at temperatures as low as minus 122§ F.

2 BASF stabilizers aid thick-walled PP
BASF Corp. said two stabilizers recently debuted in North America give exceptional performance in thick-walled polypropylene.
BASF claims its Uvinul 4050H, a monomeric hindered amine light stabilizer, maintained higher impact strength vs. a standard HALS in PP homopolymer.
Uvinul 4050H used in combination with Uvinul 5050H, an oligomeric HALS, also provides exceptional long-term heat stabilization in PP block copolymers compared with other light stabilizers, according to the Mount Olive, N.J., company.

Polycarbonate grade aimed for CD industry
GE Plastics is introducing a polycarbonate grade to the compact disc industry to meet requirements of high density CD formats.
Lexan OQ RDX is an optical-quality resin with tighter melt flow specification, up to 40 percent lower yellowness index, and improved color stability after processing.
Pittsfield, Mass.-based GE Plastics said the grade helps customers reduce flow interruptions around the disc surface and lowers birefringence within the disc.

BASF hails resins' weather resistance
BASF Corp. has debuted in North America its Terblend S resins, which it claims have better weather resistance than blends of ABS and polycarbonate while providing impact strength, heat and chemical resistance, strength and stiffness.
Terblend S is a blend of PC with acrylonitrile/styrene/acrylate copolymer. The Mount Olive, N.J., firm claims it also resists thermal aging better than ABS/PC blends. Applications include auto interiors, housings and lawn mower decks.
Terblend S KR2864 for injection molding and extrusion has melt flow of 9 cubic centimeters per 10 minutes and notched Izod impact strength of 13.1 foot-pounds per inch. KR2865WU, a V-0 flame retarded grade for molding, has a melt flow of 45 cc per 10 minutes, the company reported.
