Long-Lasting Protection for Robust Nets

CESA™ Antimosquito Masterbatch

Fights Against Malaria

The CESA™ Antimosquito Masterbatch enables the production of especially durable, efficient mosquito nets that keep their functionality for more than five years and 30 washings. Its composition of a specially formulated carrier and functionalized additives activates the incorporated alpha-cypermethrin, which acts as a strong neurotoxic agent that attacks the mosquitoes’ central nervous system – leading finally to their death.

The masterbatch formulation allows the polyethylene monofilament to orient the polyethylene molecules in a preferential direction which imparts high tenacity. Thanks to the resulting low vapor pressure of the CESA™ masterbatch, only a low amount of the active agent gets to the fiber surface at room temperature. During use of the net, the so-called glass transition temperature causes a permanent rotation of the macromolecules, ensuring a controlled release of the insecticide, and therefore permanent, consistent protection.
