LDPE
The chemical resistance of any polymer is defined largely by the chemical structure of the material and the strength of the weakest link in this structure.

LDPE has inherent lubricity and excellent chemical resistance. It is the softest and most flexible version of polyethylene.

Note: PTFE is attacked by some alkali metals (molten or in solution) and by some rare fluorinated compounds at high temperatures and pressures. Some organic and halogenated solvents are absorbed causing small dimensional changes but the effects are physical and also reversible.

The information in the Zeus eNewsletter, website, catalog, and other sources present and discuss generally accepted properties for non-pigmented virgin polymer resins from which ZEUS fabricates its line of extruded products. Actual properties may change due to processing method, resin grade, extruded dimensions, and other variables. It is the end user's responsibility to fully evaluate and test the fitness of the product for their specific application.
