The structure of Pebax® MX1717 consists of regular linear chains of rigid polyamide and soft polyether segments. This unique chemical structure allows for, through the polyether phase, the absorption and controlled release of volatile molecules (fragrances, oils, insecticides…)
As depicted in the graph below for the case of lavender perfumes, Pebax® MX1717 exhibits a high level of initial absorption (up to 50%) and a uniform and long lasting release of the fragrance compared to other supports.
The evolution in time of lavender perfume components has been measured by chromatography (Head Space Technology).
Pebax® MX1717 pellets can be impregnated before transformation through dry-blending with the volatile substances: Pebax® MX1717 can be used as a support for oils, perfumes, insecticides, and pheromones (air fresheners, insect repellent devices, etc..). |
