HDPE (High-Density Polyethylene) and PE (Polyethylene) are both types of thermoplastic polymers, but they differ in their density and molecular structure. HDPE has a higher density and a more linear structure, which gives it greater strength and rigidity compared to other forms of polyethylene, such as LDPE (Low-Density Polyethylene). This makes HDPE suitable for applications like containers and piping, while PE can refer to any polyethylene type, including both HDPE and LDPE, which are used for a wider range of applications based on their properties.
what is the difference between the PE pipe and HDPE pipe.
You don't specify anything to compare it to. If you mean the difference between LDPE and HDPE, then LDPE has branched chains which pack together loosely, making a softer material. HDPE is firmer because it has unbranched chains which pack together tightly.
PE is physical education so I say it isn't
HDPE= High-density polyethylene
one is made out of PE, the other is made out of PVC
Sometimes
Answer I'm no expert here with this but through minimal experience with HDPE pipe, PE stands for polyethylene and is used for water supply because polyethylene is neutral in water - meaning nothing in polyethylene reacts with water which would seep into the water. There are different pressure grades "PN" which must be considered for your specific use. PN 2.5 through PN16 indicate how much pressure the pipe can withstand.
High Density Polyethylene (HDPE)
LDPE is softest, HDPE is harder, PMMA is much harder than HDPE
HDpe not soluble in any solvent at room temprture
The newest generation of hovercrafts are made out of High Density PE / HDPE (Structural Polyethylene)). This material is very strong and lightweight, used previously in applications such as F1 Crash barriers. http:hover-craft.us
PE is the acronym for Poly Ethylene, a common plastic used in many consumer products and food storage containers. The real question is...is it BPA-free? and what type of PE is used (LDPE - Low Density Poly Ethylene or HDPE - High Density Poly Ethylene) and based on this, what small molecules may leach out when you put hot food on the plate or microwave it.
