AKRON (Dec. 24, 2008)—Akron Rubber Development Laboratory Inc. has purchased new equipment and software to allow the firm to perform Karl Fischer-brand water-content testing on gases, liquids and solids, including polymers.
The material was installed at one of ARDL's three Akron facilities in early November. Molding wet polymers can cause degradation, so moisture content information can be very important when processing nylon and other water-absorbing polymers, officials with Akron-based ARDL said in a news release.
The Karl Fischer technique involves heating samples at optimum temperatures, extracting water vapor and testing the water molecules in a methanol-based solution.
ARDL employs 80 and is privately owned by the Samples family, who launched the firm in 1962.
