To truly make composites the material of choice and to enable their widespread adoption, we need to make them more sustainable and recyclable.
'Aditya Birla Chemicals' Recyclamine® technology is a path-breaking & patented innovation, which has enabled epoxy thermoset composites to become recyclable. Recyclamines® are novel amine-based curing agents that contain specifically engineered cleavage points at cross-linking sites, which convert thermosetting epoxies into thermoplastics under specific set of conditions, thus helping achieve recyclability of Thermosetting Composites. Valuable reinforcing components such as carbon fiber or glass fiber as well as plastic material in a thermoset composite can be recovered and reused, thus contributing towards a circular economy.
Recyclamine® enables recycling of thermoset epoxy composites which are used in high-performance applications. These materials were hitherto non-recyclable. Both reinforcement & matrix are recovered, reused and re-integrated. Recovered fibers are in near virgin form with nominally reduced mechanical strength. Recovered epoxy thermoplastic can be reused by compounding to make plastic components.
Recyclamine® maintains or exceeds the process and performance characteristics of epoxy matrix used in composites. A wide spectrum of systems matching the requirements exactly are available – an array of flexibility, adhesion, weather-ability, toughness with systems from slow to fast, from high to low glass transition temperature, varying levels of strengths, etc.
Recyclamine is suitable for Infusion, Compression Molding, Layup, HPRTM and VARTM processes.
