Engineering Properties of Polyethylene

ENGINEERING PROPERTIES OF POLYETHYLENE 3 weight will have a comparatively high melt index. Conversely, resins with a relatively high molecular weight will yield a lower melt index. From this relationship, we can associate changes in physical properties (as shown in Table 1-1) with changes in melt index of the material.

Technical Note 803 - Pull In

causes the pipe to yield and break in a few minutes is much higher than the load that causes failure in an hour or a day. This phenomenon is known as creep. It means that the pipe''s allowable tensile load (ATL) for a half-day pull is lower than the ATL for a 1-hour pull. Published tensile strength values are

High Density Polyethylene - HDPE

May 11, 2001· Polyethylene is a whitish, semi-crystalline, and effectively opaque engineering thermoplastic which, chemically, is a very high molecular weight (3-6 million) HDPE. As a result, its melt viscosity is extremely high and normally can only be processed by powder sintering methods. Polyethylene has

strength properties – generally, in tensile strength at yield or elongation at break. Results obtained by means of an immersion test are a useful guide for appliions, such as drainage piping, in which the pipe is subject to only low levels of stressing.

NCHRP Report 429 - Transportation Research Board

The report stresses the necessity of controlling procedures for installing HDPE drainage pipe to control localized overstressing. This research did not investigate smaller diameter HDPE pipes; therefore, there are no recommendations in the report for pipes less than 300 mm (AASHTO M 252 Drainage Tubing). Furthermore, at the present time, it is

HDPE PIPE DEFLECTION: THE BENDING STRESS PROBLEM

recognized this limit by requiring HDPE material to have a minimum strength of 3,000 psi (Section 18 and M 294-98). Bending Stress is directly related to pipe deflection. Every pipe size exceeds HDPE’s bending stress limits of 3,000 psi (Figure 2) at deflection levels of 5%
