Chemical Resistance Chart

Selecting the most efficient resin for your plastic random packing application is a critical aspect of the overall design of a system. Application, temperature and chemical environment should be considered when determining which resin to use. This chemical resistance chart may provide guidance in selecting the best resin for your plastic random packing application.

KemFlo manufactures the Tri-Packs, Pall Ring and Saddle style tower packing in a variety of resins. Please contact your KemFlo customer service representative for more information.

Legend:
A = No Attack, possibly slight absorption. Negligible effect on mechanical properties.
B = Slight attack by absorption. Some swelling and a small reduction in mechanical likely.
C = Moderate attack of appreciable absorption. Material will have limited life.
D = Material will decompose or dissolve in a short time.

Aq. = Aqueous Solution
CONC = Concentrated Aqueous Solution
SAT = Saturated Aqueous Solution
* = No data available.

Where Aqueous Solutions are shown, the concentration as a weight % is given.
