Benz Materials sells brittle point tester
Benz Materials Testing Instruments is selling the Benz Brittle Point Tester BPT 2100, which tests the exact temperature at which plastics, rubber and other compounds become brittle.
The Providence, R.I., firm said the tester meets international standards, including ASTM D746 and D2137. The device, which can run as many as 10 samples at a time, indicates the temperature at which an impact of specified force will destroy them.

Digital gauge checks minor thread diameter
A hand-held gauge from Comtorage Corp. checks the minor diameter of threads inside a plastic closure.
The push of a button moves a sliding contact into position to measure the threads.
Slatersville, R.I.-based Comtorage showed its new Comtor-Digital gauge in April at the Plastics Show in Philadelphia. The device has a digital seven-digit display and a memory for five different gauges.
Comtorage also recently designed a custom blade gauge for a maker of plastic food containers to hold yogurt and cottage cheese. It measures the diameter of the inside snap groove, which secures the lid to the container.

Texas firm improves corona treatment
Corona Designs Inc. has developed a way to corona-treat plastic foam with higher dyne levels that does not damage the foam.
Treatment of polyethylene foam at one-thirty-second-inch, one-sixteenth-inch and one-eighth-inch thick with densities from 2-6 pounds at a treatment level of 40-65 dynes a centimeter, at line speeds up to 150 feet per minute.
Corona Designs also has run the same-thickness urethane foams at 40-56 dynes.
Corona Designs, of Garland, Texas, also introduced a new corona generator, PowerSource II, at LabelExpo USA '98 in Chicago. The unit is a smaller version of the firm's IGBT-based system.
Corona Designs said its equipment can treat rigid plastic sheet as thick as 0.6 inch.
