One change was to deliver the raw material in round, underwater-cut pellets rather than the square pellets provided by the other material source. New tooling was also being developed at the time, and the team was able to provide design input that minimized mold shrinkage during production. Overall, cost performance for the new material was 40 percent better than for other competitive materials – a level of value the supplier didn’t anticipate when merely seeking another source for a commodity raw material.

TPEs also allow for greater design freedom, an extended product portfolio and lower extractables. This advanced material provides cleanliness by avoiding cross-linking agents used in curing vulcanized rubber. Finetool designed its cap to meet the stringent performance, compliance and cost requirements of its OEM, a leading producer of sterile IV solutions.

These new materials also solve the long-standing problem of undesirable water absorption levels in other bio-derived polyamide materials available today. Renewable, plant-based raw materials, have been shown to offer significantly lower product carbon footprint values than typical petroleum-based feedstock. Our new Nymax BIO line of bio-based polyamide formulations exemplifies our continuous innovation in developing sustainable materials, and expands the material choices for design engineers while mitigating the risk of water absorption.”

Most of the new TPEs are designed based on the concept of matching the surface energy between the TPEs and the substrates. This new technology opens up unprecedented opportunities for new designs where the TPEs need to bond to dissimilar substrates. Each formulation was designed to selectively bond to a substrate based on the functionality of the substrate material.

The Milipol Innovation Awards were designed to honor the most innovative companies in products, materials, services, solutions or business models related to the homeland security industry. Avient Corporation provides specialized and sustainable material solutions that transform customer challenges into opportunities, bringing new products to life for a better world. Light-weighting solutions that replace heavier traditional materials like metal, glass, and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint
