Rubber Blowing Agent is a chemical added to rubbers that generates inert gases on heating causing the resin to assume a cellular structure It is also known as foaming agent Our company specialises in the production and distribution of highly acclaimed Rubber Blowing Agent that is also reckoned as

The blowing agent decomposes before the curing progresses significantly and expansion takes place to the desired thickness governed by the spacing between the platens At the end of the platens the cure has been completed and the sponge is rolled up Continuous curing in a liquid is utilized in the production of both solid and cellular extruded goods In this case the uncured stock passes

ensuring that the blowing agent and other reagents remain compatible and in the same phase during the aging studies [3] Dabco DC193 is a silicone polyether surfactant that provides excellent foam stability and has been shown to give good performance in flammability testing of the finished foam [4] The blowing agents used in this study are 1 1 1 3 3-trifluoropropane (HFC-245fa available from
