How strong is Tripolymer?
A. Samples of Tripolymer have been taken from tanks that have been buried for over 25 years and tested for compressive strength according to ASTM procedure D-1621 (Industry Standards). The tests confirmed that these samples had a compressive strength of 32 to 42 pounds per square inch at the standard 2 pound density. Tripolymer’s density can be easily increased if necessary.
