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.

2 Why is HDPE a good material for boats?
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
What is the difference between powder and ceramic coating?
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
What type of plastic is a detergent bottle made of?
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.
Difference between PE and HDPE pipes?
what is the difference between the PE pipe and HDPE pipe.
What is difference between LDPE and HDPE?
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.
What is the difference between high and low density polyethylene?
density of HDPE
