High Density Polyethylene (HDPE)
HDPE stands for High-density polyethylene, which is made from petroleum. It is a plastic used in many water bottles, plastic bags, and corrosive-safe piping.
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= High-density polyethylene
Because LDPE is an abbreviation of Low Density Poly Ethylene, whereas HDPE stands for High Density Poly Ethylene. This means LDPE is less efficiently packed together than HDPE, due to the larger amount of branching found in LDPE, leading to a weaker material.
This is used for US made waterbottles
Sometimes
LDPE is softest, HDPE is harder, PMMA is much harder than HDPE
HDpe not soluble in any solvent at room temprture
HDPE stands for High-Density Polyethylene. It is a type of plastic that is known for its high strength-to-density ratio, making it a popular choice for various applications. HDPE is produced from petroleum through a process called polymerization. It is commonly used in packaging, such as bottles and containers, as well as in pipes, geomembranes, and other industrial applications due to its chemical resistance, durability, and low moisture absorption properties. HDPE is also recyclable, making it an environmentally friendly choice in many contexts.
