Avient and IVCC created a new medium scale masterbatch production laboratory in China to support research and development into non-registered novel active ingredients for incorporation into long lasting treated nets. Avient has extensive global ability in the formulation development and manufacturing of groundbreaking material solutions to support malaria control, including a technologically advanced anti-mosquito masterbatch for use in long lasting treated nets. The novel insecticides in development are formulated tightly into the masterbatch, allowing best bio-efficiency performance with a permanent but slow release to the surface—just enough to kill any mosquito by contact.
