Medium-density polyethylene - Wikipedia

Medium-density polyethylene (MDPE) is a type of polyethylene defined by a density range of 0.926–0.940 g/cm 3. It is less dense than HDPE, which is more common.. MDPE can be produced by chromium/silica alysts, Ziegler-Natta alysts or metallocene alysts.MDPE has good shock and drop resistance properties.

HDPE | LyondellBasell

HDPE grades are used in a variety of processing techniques such as extrusion, extrusion blow molding, injection and rotational molding. HDPE forms the largest product family in polyethylene, and is used in numerous customer appliions such as pipe, plastic fuel tanks, industrial packagings, bottles, healthcare articles, containers, toys, films, tapes and fibers.

HDPE | Designerdata

and a relatively high Young''s Modulus. HDPE is a popular construction material for containers for liquids and food, due to the good ductility, good chemical resistance and food-safety: many PE grades are FDA approved. The total production volume of all PE

LDPE | Designerdata

This is the reason why the density of LDPE is lower than of HDPE. Due to the lower crystallinity the Young''s Modulus is also lower, because the glass transition temperature is (as with all PE’s) far below room temperature. However, this makes LDPE very ductile, even at low temperatures.

Determination of Tensile Elastic Modulus in High Density Polyethylene

Polyethylene pipe can be installed at much lower labor costs than carbon steel pipe and High Density Polyethylene pipe has a much greater resistance to corrosion. Data was developed by the three testing tasks for use in the seismic design of above ground High Density Polyethylene Piping systems. This paper presents the results of testing to determine the relationship between tensile elastic modulus …

What is Young''s Modulus? - Definition from Trenchlesspedia

Young''s modulus is a measure of the stress buildup associated with a given strain, or the modulus of elasticity of pipe material (psi). Young''s modulus is a numerical constant that describes the elastic properties of a solid under tension or compression in a single direction.
