1. As the above chart is for generic polyethylene, ACO recommend that customers use a prototype for determining the
suitability for specific applications
2. Generally an increase in temperature & concentration results in increased attack
3. A chemical which exhibits a limited attack would be suitable for slightly longer exposure to the chemical, and likewise,
a chemical which shows extensive attack on polyethylene would only be suitable for very short exposure times.
