Rheologic Control Compound for Rheometer
Statistical process control is a fundamental key to success in today's high precision, high volume, continuous process production in the rubber and plastics industries. Instrument calibration to standard references with continual monitoring is the key to statistical process control. Without it, keeping your production on-line and on-spec is nearly impossible.
Akron Rubber Development Laboratory, Inc. (ARDL) is the source for your lab's vital control material - a standard compound for Rheometer process control. This product, a certified SBR compound chosen for its reproducibility, is produced by ARDL under carefully controlled and monitored conditions. This reference material is available with certified characteristics. The following results are typical: (See note 1)

This material must be maintained at below freezing temperatures (32°F or 0°C maximum) at all times. Failure to maintain the material at below freezing temperatures may render the material unsuitable for reference use and reduce its shelf life significantly.
The standard reference compound should be warmed slowly, under ambient conditions, for 8-24 hours prior to use. Keep wrapped during warm-up to prevent condensation from forming and causing moisture absorption. ARDL recommends using the control compound for each Rheometer a minimum of once per day for routine laboratory operations and once per shift for continuous, 24-hour operations.
Warranty and Certification
ARDL certifies that this reference compound, when properly stored and used, will exhibit reproducible results as illustrated on the front page. ARDL makes no other warranty, either stated or implied.
