THE SOLUTION Gravi-Tech™ density-modified formulations are unique, high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals.

They offer a more sustainable alternative to traditional polyolefin grades while achieving equivalent performance.

Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation from, or solely as alternatives to, financial measures prepared in accordance with GAAP.

THE IMPORTANCE OF PLASTICS FOR PACKAGING Compared to alternative materials, plastic is one of the most sustainable materials available for packaging applications.

Good processability – Cycle times for injection molded TPEs are typically faster than alternative materials, resulting in reduced costs with chemical compatibility performance.

UNIVERSALLY COMPATIBLE As Triple A is universally compatible across a wide range of resins, it can also reduce handling complexity which can be a problem with alternative technologies.

This region of the world maintains a high sensitivity to preserving nature and the environment, and the producer’s desire to look for alternative material solutions not yet required by law follows this cultural tendency.
