Drum Feed Clamps Compatibilty

Chemical Feed Safety Drum LocksChemical Feed Safety Drum Locks - Filter Chemical Resistance Guidance & Ratings

The data summarized below is derived from direct testing of products and extrapolation of data available on the chemical resistance of the base polymer of our Chemical Feed Drum Lock inner filters. The outer clamps are made of polypropylene, but the inner filter has the most interaction with the chemicals in your feed drum, so the chart below refers only to the filter compatibility. Filters are made of cross-linked, closed-cell Plastazote® LDPE.

Please note: The data in this table should only be used for guidance purposes. If chemical resistance is critical we recommend testing of the material under end use conditions to determine the suitability of the foam for a specific application.

The ratings given in the table are based on exposure at 20°C. The effects of each chemical have been graded from 0 to 4 using the following system:

Grade  Effect Foam life expectancy
0
Virtually no effect Satisfactory for long term continuous contact over several years
1
Minimal effect Satisfactory for continuous contact over several months
2
Some effect w/ noticeable deterioration Satisfactory for intermittent contact; Continuous contact several weeks
3
Substantial effect Satisfactory for short term contact; Continuous contact several days
4
Catastrophic effect Not recommended expect for incidental contact; Deterioration of properties within hours

* Inorganic salts generally have no effect (0 rating)
** Hydrocarbons or chlorinated solvents in solvent based adhesives evaporate quickly and are unlikely to have any effect on foams in normal use.
