Luperox® 223M75 (223M75S) polymer initiator
Luperox® 223M75 polymer initiator is a 75% active solution of EHP with added organic solvent. Luperox® 223M75S polymer initiator is the same solution, but with an added stabilizer that increases the self accelerating decomposition temperature (SADT). The stabilized solution is widely used in emulsion PVC polymerizations. High pressure applications such as tubular production of LDPE use the 223M75 solution without stabilizer.
