Alvinox FB is a highly efficient primary antioxidant designed for polymers, featuring a chemical structure with three sterically hindered phenolic groups. Primarily acting as a "radical scavenger," it effectively interacts with peroxy radicals, thereby impeding the chain reaction process and mitigating thermal oxidation. Suitable for a diverse range of polymers, including polyolefins, polyamides, polycarbonates, styrenics, adhesives, elastomers, and latex, Alvinox FB can be used alone or in conjunction with other antioxidants under the Alvipack brand name, ensuring exceptional performance across various applications.

UVASORB® HA88 FD is particularly efficient in thin layer applications such as fibers, films, tapes and coatings, calling for minimal migration and low volatility. UVASORB® HA88 FD is also used in automotive, drums, bottles, crates, sheets, toys, marine and garden furniture applications.The performance of UVASORB® HA88 FD may beimpaired by substances containing halogens and sulfur (pesticides, flame retardants, some stabilizers, etc.).

UVASORB® HA19 is particularly efficient in thin layer applications such as PA, PET and PP fibers, films, and coatings, calling for minimal migration and low volatility. The enhancing of color yield in pigmented PP articles makes the product particularly recommended in PP fibers. UVASORB® HA19 is also recommended as an outstanding long-term thermal stabilizer in filled PP thick sections, containing carbon black, typical of automotive applications; its use allows to avoid the use of sulfur based costabilizers when the odor is not desired.
