Applications
PowerStab™ 7794 is especially suitable for the protection of polyolefins such as PP, PE, PP/EPDM and PP/PE/EPDM blends from the damage of UV radiation. Due to its synergistic effect, it is extremely good for thick applications where the efficacy and long term protection are needed to be considered at the same time.
PowerStab™ 7794 can also be used in styrenic polymers, e.g. ABS, impact polystyrene, etc.
Packings
PowerStab™ 7794 is supplied in net weight 25kg fiber drum with PE liner.
