The most widely used additives for the prevention of plastic degradation.
There are primary scavengers which stabilise peroxide radicals, and secondary scavengers which enhance the effect of the primary scavengers.
Primary scavengers which scavenge oxide radicals. Two types with low colouration derived from antioxidants are available.
An antioxidant with excellent weathering properties. It can be used for all types of resins, particularly effective on ABS and HIPS for its low discolouration.

When used for polyolefins, it has an excellent effect on long-term ageing protection and process stabilisation. For fibres and films with a large surface area, it has an outstanding inhibitory effect on yellowing caused by NOX gas.

Secondary scavengers which stabilise the thermally unstable by-products of primary scavengers. As they have good compatibility with hindered phenol antioxidants, especially with KEMINOX 9425 and KEMINOX 179, high thermal stability is obtained when used in combination.
Combined use with hindered phenol antioxidants has an outstanding synergetic effect, adding long-term thermal stability to polymeric materials.
