Thermoplastic Elastomers for Overmolding Applications The growth of the thermoplastic elastomers continues over the last three decades and the projections are very optimistic3. As an example, in order to bond to engineering thermoplastic, the continuous phase in a TPV has to be modified significantly. Polypropylene which is normally the continuous phase in a TPV does not lend itself for functional modifications needed to meet the adhesion requirements for a wide variety of engineering thermoplastics that are being used in the consumer market.

Examples include: • Barrier technologies that preserve the shelf-life and quality of food, beverages, medicine and other perishable goods through high- performance materials that require less plastic • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation • Breakthrough technologies that minimize wastewater, improve the recyclability of materials and advance a circular economy • Composite solutions to support accelerated growth of 5G / fiber-optic infrastructure investment as the world demands greater and faster connectivity Avient employs approximately 8,400 associates and is certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste. Operational Excellence Empowers us to respond to the voice of the customer with relentless continuous improvement. We will do so though our investments and focus on sustainable solutions for high-growth markets, including healthcare, consumer, packaging and composites/5G.
