This morning one of my friends asked me to go with him to buy some pipes made of HDPE (short for High Density Polyethylene), for his house. I didn’t know what HDPE is but I found out… on Google. 
High-density polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. It takes 1.75 kilograms of petroleum (in terms of energy and raw materials) to make one kilogram of HDPE. One of the largest HDPE produces is Raw Polymers Ltd.
HDPE Chemical Resistance
- HDPE is very resistant to alcohols, acids and bases.
- HDPE has a good resistance to vegetable oils, mineral oils, ketones, esters, and aldehydes.
- HDPE has little to no resistance to oxidizing agents and halogenated hydrocarbons.
One of the largest uses for HDPE is wood plastic composites, with recycled polymers leading the way. Here is a picture with the pipes:
HDPE is the high density version of PE plastic. It is harder, stronger and a little heavier than LDPE, but less ductile. The appearance is wax-like, lustreless and opaque. The use of UV-stabilizators (carbon black) improves its weather resistance but turns it black. Some types can be used in contact with food.
Lol, technology. Everything is evolving. I wait the day when cars will function with air.
