Materials supplier Avient Corp. has introduced a mold-release additive for high-temperature polymers that is formulated without intentionally added per- and polyfluoroalkyl substances (PFAS). The new Evoluscend additive, part of Avient’s Colorant Chromatics portfolio, can be used to enhance the high-pressure injection molding process.
PFAS chemicals, aka forever chemicals, are used in a broad range of products but have come under scrutiny in recent years for their environmental impact and potential health risks. Globally and domestically, regulatory agencies and legislative bodies are taking steps to reduce or eliminate their use.
Additive reduces cycle times
The additive integrates directly into plastic materials and migrates to the surface to facilitate de-molding, helping to reduce cycle times and boost productivity while protecting the mold and manufactured plastic parts. Evoluscend is effective across a range of high-temperature polymers, including PPSU, PES, PSU, PEI, LCP, PPS, and PEEK, said Avient. Furthermore, it can be combined with polymer colorants where color design is desired in a mold-release application.
Key features include:
High-temperature resistance across a range of polymers, with a maximum service temperature exceeding 150°C;
a PFAS-free alternative to traditional products, supporting manufacturers' sustainability goals and regulatory compliance initiatives;
lubrication properties, minimizing mold damage;
enhanced de-molding, improving productivity and throughput.
Pre-tested to FDA food-contact requirements and ISO 10993 (subparts 4, 5, 10, and 11) requirements for healthcare applications, the Evoluscend mold-release additive for high-temperature polymers is available to manufacturers globally.
