Why crosslink polyethylene?
Pfeiffer says, “If you have a tank failure with sodium hypochlorite using a linear polyethylene tank, there’s a possibility that the tank could catastrophically fail. The reason for this is molecules in linear high-density polyethylene link up in long strands. Crosslink polyethylene has a molecular structure where all molecules are linked together making a stronger tank for harsh chemical services. Sodium hypochlorite is a chemical that hardens the tank wall and attacks the UV stabilizer compounded into the raw material. Using high-density linear polyethylene that is already a hard material may cause the tank to prematurely fail. Since all of the molecules in crosslink polyethylene are linked together, the tank will better withstand abuse from impact or chemical attack. Therefore, it’s a safer more reliable tank. From a safety standpoint, crosslink polyethylene is a stronger, safer material.
