Polyethylene Resins—U.S.I. Chemicals

PETROTHENE resins are available across the entire range of polyethylene densities 0.91 to 0.96. The variations in density appear very small, but the effect of even a very small change in density on certain essential properties is very marked. There are many applications for which resins of higher density and many others for which those of lower density may be preferable. The three density ranges of polyethylene are  

Low density Medium density High density (linear) 

Chemical Resistance of Low and Medium Density Polyethylene to Various Reagents
