Bleach Hdpe
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.
Bleach hdpe. Secondary containment is required. 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 resistance guide legend. S satisfactory o some attack u unsatisfactory. When storing this chemical three factors must be considered.
I presume you re talking about common household bleach like clorox brand which is a sodium hypochlorite solution as opposed to household oxygen bleaches sometimes dubiously referred to as color safe bleaches or the many commercial bleaches. Sodium hypochlorite bleach is used in a variety of applications particularly in disinfecting drinking water and wastewater. However preliminary tests showed that chemical interaction between hdpe and bleach occurring within six month of exposure to the product has a negligible effect on the materialâ s mechanical properties.
Hdpe and ldpe at 20c show some effect after 7 days. Polypropylene is almost as resistant as polyethylene but with a few specific chemicals it offers superior resistance. Softening loss of strength.
Satisfactory to 120 f 48 c ratings chemical effect a excellent. Bleach is best stored out of direct sunlight at temperatures below 60 f filtered and diluted with ph kept above 10. It can also be autoclaved and is better for use.

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. Prices range from 300 to 150 000.
Hdpe chemical compatibility resistance chart explanation of footnotes 1. B good minor effect slight corrosion or discoloration. Sodium hypochlorite storage tanks are manufactured from hdpe xlpe and frp materials at 1 9 specific gravity.
Therefore in this work esc was investigated independently and only the results obtained from fracture tests are reported. At 50c immediate damage may occur. Uv can degrade sodium hypochlorite so special precautions must be taken to reduce this effect.

Soap and water is all that is need to clean and reuse the bottles.
