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).

Because FIBER-LINE® already processes so many different types and deniers of both Kevlar® & Nomex®, FIBER-LINE® have been authorized by DuPontTM to distribute small quantities of these fibers to an ever- growing customer base.

Working closely with the manufacturer’s engineers, Avient determined that the material required a special combination of properties: • A heat-resistant base resin that would provide the level of signal dampening prescribed • Mechanical properties that would ensure an effective electrical connection and at the same time allow for snap-fit installation • A cost-effective solution that would enable the manufacturer to compete in this new market Striving for optimal results, the manufacturer evaluated more than 30 different materials.

Compared to different types of food & beverage packaging, PET is often preferred because of it’s high clarity, can be easily recycled many times and offers brand owners freedom of design to differentiate their product packaging to create greater shelf appeal.
