CHEMICAL RESISTANCE CHART

We tested this material with different solvents both in our lab and with real customers in the field. Keep in mind that resistance levels can change at different temperatures or when solvents are mixed together. Use this data as a general guide. We regularly update our solvent resistance table as we gather more data, and you can download the complete list below.
