Tert-Butyl Peroxyneodecanoate - Perodox® 23
CAS: 26748-41-4
An initiator for the (co)polymerization of ethylene, vinyl chloride, vinylidene chloride, (meth)acrylates and diethylene glycol bis(allyl carbonate) based optical monomers.
Product Overview
Perodox® 23 is an efficient initiator for the production
of Low Density Polyethylene (LDPE). It is used both for
tubular and autoclave processes. In most cases a
combination with other peroxides is used to ensure a
broad reactivity range. Perodox® 23 can also be used
for the polymerization of diethylene glycol
di(allylcarbonate) based optical monomers. The use
level of Perodox® 23 will depend on the particular cure
parameters being used. Perodox® 23 has an activity in
between peroxydicarbonates and tert-Butyl
peroxypivalate (Perodox® 25). Perodox® 23 can be
applied as an initiator for the suspension polymerization
of vinyl chloride in the temperature range 50-65°C. The
obtained polymer has a good thermal stability.
tert-Butyl peroxyneodecanoate (TBPND), also known as BNP or TBPD, is an organic peroxide compound widely used as a radical initiator in polymer chemistry. It serves as a medium-temperature initiator for various polymerization processes with excellent decomposition characteristics.
