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). Other contaminants may affect product quality in various ways depending on the contaminant type and level.

Also, it is common for nylons reinforced with glass fiber to have an inconsistent surface appearance that can be mistaken for poor product quality. Complēt moisture resistant nylons reinforced with long glass fiber produce a smooth, fiber-free finish without special processing to give molded components a high-quality appearance.
