LDPE is softer, more flexible and melts at lower temperatures than HDPE. LDPE is used for things like sandwich bags.
HDPE is harder, has a higher chemical resistance and can withstand higher temperatures. (120 Degrees Celsius for short periods and 110 Degrees Celsius continuously) It is used for things like Plastic bins.
HDPE is High Density Polyethylene and HMHDPE is High molecular weight High density polyethylene
linear LOW Density PolyEthylene
HIGH Density PolyEthylene
no it is plastic
enthalpy LDPE
HDPE is a plastic that is lower density than polyethylene, yet has a high tensile strength. So, combined with fiberglass it is good for boat building. Boats are not built just out of fiberglass, but of fiberglass and a plastic resin. Below is a link that explains HDPE better, and it's most popular uses.Source(s):http://en.wikipedia.org/wiki/HDPE
Powder coatings are flexible, have good weatheribility and mehcnical properties. Powder coatngs generally cure at 200 deggree for 10 min Powder coatings could be theromosetting (polyester or epoxy) or thermoplastic (LDPE, HDPE etc) Powder Coatings have limited chemical resistance. Ceramic coatings are generally brittle. Have excellent chgecmical resistance Cure at around 800 seegree centigrades
Generally detergent bottle are made of high density polyethylene (HDPE) and polyethylene terephthalate (PET) depending on the detergent type if it is washing liquid or soap then PET is preferable due to its transparency properties. HDPE is more preferable for other type of detergents such as bleach, shampoo etc. and these products are highly chemical which requires a good chemical resistance. Therefore, HDPE has better properties for detergent container purposes; excellent flexural strength, good impact strength, very good chemical resistance, good fatigue resistance and service temperature to 126 °C. HDPE detergent bottles can be manufactured by extrusion blow moulding as it is suitable for mass production and cheaper than other techniques.
what is the difference between the PE pipe and HDPE pipe.
density of HDPE
LDPE (Low-Density Polyethylene) has more branching in its molecular structure than HDPE (High-Density Polyethylene), giving it a lower density and flexibility. HDPE is more rigid and has a higher tensile strength compared to LDPE. LDPE is commonly used for packaging and bags, while HDPE is often used for bottles and containers.

HDPE= High-density polyethylene
Sometimes
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
PMMA LDPE HDPE
