Every effort will be made to be impartial on the pro’s and con’s. HDPE is high-density polyethylene. When it comes to HDPE and PP plastic, there are a lot of similarities, which makes it easy to confuse the two materials when it’s time for your manufacturing project. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry. However, deciding between HDPE and PP plastics can result in stark differences in your overall end products. HDPE pipe can also be transitioned to and from non-HDPE piping systems that utilize Mechanical Joint adapters (MJ’s), Stab fittings and Mechanic. There are many applications of HDPE. PVC VS POLYETHYLENE (HDPE) PRESSURE PIPE OCCASIONAL SURGE PRESSURE: PVC PIPE OUTPERFORMS HDPE. It has higher strength, is harder, and can withstand high temperatures. Take for example, plastic bags. In the end, there are several advantages associated with using HDPE and PP that businesses will want to look at before making a final decision. The Main Differences between HDPE and PVC October 22, 2018. The HDPE pipe is a kind of PE pipe. 1.

Your Guide to Using Plexiglass in Your Next Project. However, HDPE can remain flexible as well. It is a form of polyethylene. Thus the key difference between HDPE and PP is that the HDPE is made with ethylene monomer whereas PP is made with propylene monomer. Usually, a PE resin with a large molecular weight and good mechanical properties, such as HDPE resin. Our HDPE and HDPP cutting boards are NSF stamped, as well as FDA and HACCP certified for food service use. Compared to other vinyl types, this is perhaps the strongest. Johnson, Todd. The … The density of HDPE is equal or higher than 0.941 g/cm3. On the other hand, PVC is a much stronger and stiffer material, which is why PVC pipes are more widely used for direct burial and trenchless installations.
