Hamilton Avtec Inc. of Mississauga, Ontario, has a new full range of systems for loading PVC compounds and other filled materials. Individual vacuum loaders use a new carbon filter with an increased air-to-filter ratio. A safety switch in the vacuum chamber prevents material from overfilling and blocking the filter.

Rheometric Scientific Inc. has introduced what it claims is the first rheometer with integrated thermal analysis capabilities.
The Differential Thermal Rheometer enables a sample to be tested rheologically and thermo-analytically at the same time.
The Piscataway, N.J., company also announced their Dynamic Stress Rheometers SR-200 and SR-500 now have the ThermoGap, which automatically varies the gap between plates to compensate for expansion or contraction in the fixture molding the sample. The units also measure actual normal force, rather than just axial force.

Ceramer improves abrasion resistance and lowers creep, according to the Frankfurt am Main, Germany, company. It also improves metalizability of compounds, particularly those made with fluoropolymers.
It is supplied as a fine powder that bonds well with other polymers. Hoechst said Ceramer has high thermal stability and chemical resistance.

Macbeth division of Kollmorgen Instruments Corp. has a new spectrophotometer as part of its color control solutions for the plastics industry.
Color-Eye 7000A is a dual-beam, bench-top instrument for lab and manufacturing use. It features improved efficiency through automation of ultraviolet control, gloss effects and other functions. Its touch-screen display makes it easy to configure the instrument, the New Windsor, N.Y., firm said. A new thin film sample holder allows diffuse or direct color transmission measurement.

Omni Technologies Inc., a custom compression molder of polyurethane components primarily for the packaging machine industry, plans to expand its Hebron, Ky., plant by about 12,000 square feet.
The addition will allow for business expansion, said James Riddell, co-owner of Omni, which operates in 14,000 square feet of space. Riddell said he hopes construction can begin this fall.
Omni operates 25 compression molding lines, and provides in-house mold-making and secondary operations.
Recently, Omni completed one of the world's largest poured PU parts for a division of Emerson Electric that produces a line of finishing and grinding mills. The units have a durable PU lining inside the grinding chamber.
The division shipped the unlined chamber, which measured 8 feet tall by 12 feet in diameter and weighed 25,000 pounds, to Omni, where it was set upright and a mold placed inside.
Thickness of the poured lining varied from 1-3 inches, depending on where the most wear will occur when the grinding chamber is in operation. The application called for 1,600 pounds of poured polyurethane.

Euclid Quantum is Matra Datavision Inc.'s new software for computer-aided design, manufacturing and engineering.
The Andover, Mass.-based firm said Euclid Quantum features open architecture, meaning it can be used with other software programs. Euclid Quantum is based on Matra's CAS.CADE software development platform, which accepts both Unix and Windows.
Until now, Matra said, three-dimensional modeling has been only geometric. Euclid's Designer software includes both geometry and design intent. It combines information such as aesthetics, function, material selection and the method of fabrication. Matra is part of the $10 billion Lagardere group of Lesulis, France.
