When properly selected, overmolded TPEs will form a strong bond (a cohesive bond) with the thermoplastic substrate without the need for primers or adhesives. With that widespread availability also comes a wider selection of mold metals and production techniques. Selecting the right material for your application can have multiple nuances, from properties and processing to design and appearance.

In addition selection of the overmold TPE depends on the end-use application and environment. Thinner coatings and the selection of a lower hardness over-mold grade will also help. In the selection of TPE hardness the thickness should be taken into account to get the right feel and esthetics on the product.

High-temperature polymers (HTP) processed include: LCP, PEEK, PAEK, PEKEKK, PEI, PES, PSU, PPSU, and PPS FLUOROPOLYMERS Colorant Chromatics has extensive experience in selecting the best pigments and additives for optimal performance under demanding circumstances.

To withstand the high temperatures of the sintering step in the PTFE process, Colorant Chromatics selects the appropriate heat-stable pigments

In general, nominees are selected on the basis of the following criteria, among others: business or professional experience; knowledge and skill in certain specialty areas such as accounting and finance, international markets, physical sciences and technology, or the specialty materials industry; personal characteristics such as ethical standards, integrity, judgment, leadership, and the ability to devote sufficient time to the affairs of the Company; substantial accomplishment with demonstrated leadership capabilities; freedom from outside interests that conflict with the Company’s best interests; the unique backgrounds and experience they will bring to the Board, including differences in viewpoint, background and skill; and the needs of the Company from time to time. Board Leadership Structure The Board selects the Chairman of the Board and Chief Executive Officer and determines from time to time whether the positions are to be combined and filled by one person or separated and filled by two persons. If the positions of Chairman of the Board and Chief Executive Officer are held by the same person or if the Chairman of the Board is otherwise not an independent director, the Board, upon recommendation from the Governance and Corporate Responsibility Committee, will select one of the independent directors who has served for at least one year on the Board to serve as the Lead Director.

With on-time delivery as a standard and additional technical assistance when needed, Avient experts can provide support in selecting the best material for your application.

Selected for their strong performance and durability, phthalates are the most commonly used plasticizers in the world.1 In recent years, concerns have been raised over the use of phthalates, giving rise to myths and unfounded speculation.

Ultimately, the company selected a Versaflex™ OM overmolding grade that bonded tightly to the polycarbonate (PC) substrate of the grips without the need for adhesives.

When closurelogic turned to Avient for material selection help, the team developed a GLS™ TPE (thermoplastic elastomer) based on a stable, low migration TPE with a lower processing temperature compared to competitive TPEs, thus resulting in even fewer volatiles.

Finally, with headquarters, manufacturing sites, and engineers spanning the globe, it was important that the collaborator DENSO selected could operate internationally as well as on a local scale.

As part of our commitment, we publish Avient’s Mevopur™ product policy and use limitations to assist customers in their product selection.
