Plastic Compatibility

EnTron solvents are designed for high performance in critical cleaning applications. However, like other halogenated solvents of similar characteristics, EnTron will effect certain types of plastics. Tests were conducted as a general guideline for consideration of the possible effects of EnTron on various types of plastic with the following results and general conclusions based on observed weight gain/loss and surface degradation/softening:

Legend: A= no effects observed, B = minor effects, and C = significant effects
