Most of the time, we would change the grade of polypropylene we ordered, rather than compound the material at the plant.  Can you compound the polypropylene?

Search Dow Chemical website.  A small amount of "Infuse" olefin block copolymer could help. 

In addition, straight up ethylene propylene block copolymer might do the trick (Sunoco 4015 is a impact copolymer).
