Bleach Hdpe
Sodium hypochlorite storage tanks are manufactured from hdpe xlpe and frp materials at 1 9 specific gravity.
Bleach hdpe. Chlorine 10 in water hdpe and ldpe at 20c shows little or no damage after 30 days. Satisfactory to 72 f 22 c 2. Hdpe chemical compatibility resistance chart explanation of footnotes 1.
Bleach is best stored out of direct sunlight at temperatures below 60 f filtered and diluted with ph kept above 10. Hdpe chemical resistance guide legend. At 50c immediate damage may occur.

Polypropylene is almost as resistant as polyethylene but with a few specific chemicals it offers superior resistance. Polyethylene hdpe and ldpe has a very good compatibility rating with most chemicals and is resistant to strong acids and bases as well as gentle oxidants and reducing agents.
Tank capacities range from 35 to 100 000 gallons. Sodium hypochlorite bleach is used in a variety of applications particularly in disinfecting drinking water and wastewater. S satisfactory o some attack u unsatisfactory.
Not recommended for continuous use. C fair moderate effect not recommended for continuous use. B good minor effect slight corrosion or discoloration.
Ldpe at 50c shows damage and is not recommended. When storing this chemical three factors must be considered. Satisfactory to 120 f 48 c ratings chemical effect a excellent.
Therefore in this work esc was investigated independently and only the results obtained from fracture tests are reported.

Secondary containment is required.
Hdpe and ldpe at 20c show some effect after 7 days. Prices range from 300 to 150 000. It can also be autoclaved and is better for use.
Softening loss of strength. Uv can degrade sodium hypochlorite so special precautions must be taken to reduce this effect. High density polyethylene abbreviated as hdpe is a type of plastic commonly used to make milk jugs laundry detergent containers soda bottles and floating water tanks.
If you wish to reuse a high density polyethylene bottle it must first be cleaned.
