What does HDPE stands for in waterbottles?
High Density Polyethylene (HDPE)
HDPE pipe is high-density polyethylene plastic pipe often used for drainage in household plumbing. HDPE is also used for electrical and communication applications. HDPE is available with different diameter and wall thickness dpeneding upon the application. It is also available with UL rating. HDPE pipes can be used for water supply, dredging, gas supply, mining used and so on. Luoyang Max Import & Export Trading Co., Ltd. is prefessional in HDPE pipes. Welcome to your…
HDPE or High Density Polypropylene is used in the manufacturing of most plastic items in production. Some of these things include soda bottles, plastic cups, hard plastic toys, and multiple other items. Now HDPE plastic is widely used for production of HDPE pipes in water, dredging, gas, mining and so on. Luoyang Max Import & Export Trading Co., Ltd. is specialized in HDPE pipes production.

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
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.
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.
