In our September issue, we incorrectly stated (p. 17) that Asaclean U

high-performance purging agent is not suitable for polypropylene. It

is suitable for most resins, including PP. However, the supplier, Sun

Plastech, Inc., Parsippany, N.J., does have another grade, Asaclean

UP, recommended specifically for PP, due to its greater compatibility.
