Vazo™ 67 container
Vazo™ 67 is an oil soluble azonitrile compound that is used to safely and efficiently initiate free radical polymerizations.
CELOGEN® 760A container
Self nucleating chemical blowing agent for thermoplastics and rubber that prevents cyanuric acid plate-out forming deposits on dies, molds, and screws.
Vazo™ 64 container
Vazo™ 64, also known as Azobisisobutyronitrile, is a free radical initiator that is used to initiate the polymerization of specialty polymers.
CELOGEN® OT container
Outstanding chemical foaming agent with a relatively low decomposition temperature for producing cellular rubber and expanded plastic. Similar to CELOGEN® OB, but it has been oil treated to reduce dusting.
Vazo™ 52 container
Vazo™ 52 is an oil soluble azonitrile that is used as a free radical initiator in low temperature polymerizations of large molecular weight polymers.
Vazo™ 88 container
Vazo™ 88 is an oil soluble azonitrile free radical initiator that is used for initiating high temperature bulk, solution, and suspension polymerizations.
CELOGEN® OB container
Outstanding chemical foaming agent with a relatively low decomposition temperature for producing cellular rubber and expanded plastic.
OPEX™ 80 container
OPEX™ 80 is an 80% active nitrogen foaming agent. It is ideal for both open and closed cell elastomeric sponge rubber and for use in microcellular soles and molded sponges made of natural, SBR, and neoprene rubbers.
CELOGEN® 780 container
Chemical blowing agent with a very low decomposition temperature designed for use with silicone gums that does not require the addition of an activator.
