Director Gordon Harnett was not up for re-election, having reached the company’s required retirement age.

These heat-stabilized formulations maintain tensile strength and tensile elongation properties when tested for long-term thermal aging up to 120°C.

One major reason is the aging of the population and all its ramifications.

The rate of increase is dependent upon a number of factors, including the plastisol formula, age and storage conditions. As a result of these plastisol aging characteristics and the potential differences in testing methodology, it is strongly recommended that incoming quality control (QC) specifications not be established based on plastisol Technical Data Sheets (TDS), or Certificates of Analysis (COA).
