Homepage // News Center // Avient Launches Medical TPE Grades Formulated Without Animal Derivatives CLEVELAND – July 31, 2020 – Avient Corporation, a leading provider of specialized and sustainable material solutions, today announced the addition of eight new grades to its healthcare portfolio of Versaflex™ thermoplastic elastomers (TPEs).

Formulated using select metallic fillers and engineered thermoplastic resins, these solutions offer densities similar to traditional metals while also providing design and processing flexibility because it can be extruded, molded, calendered or thermoformed into the final desired shape.

The adhesion is categorized based on adhesive failure (A)- if no TPE residue is left on the substrate, or cohesive failure (C)- if the failure is in TPE. Design Considerations The material requirements of bondable TPE’s are different from conventional TPE’s and it is the same for designing parts. Prevent the TPE from flashing over areas on the substrate. 4.

This extruded polymer jacketing is available up to 17.0 mm.

Plastics processing periodically requires the complete removal of thermooxidized deposits from extruders and injection molding machines.
