ChemSpec, Ltd. distributor for Birch Chemicals for rubber accelerators

Rubber Compounding: ChemSpec, Ltd. distributes Innovox Calcium Oxide. The folks at Birch Chemical say that: “Innovox is an essential ingredient in rubber compounds that are vulcanized at atmospheric pressure. It can be used in both natural and synthetic rubber based compounds that are to be extruded and continuously vulcanized into either foamed or solid sections.Minimal porosity will be achieved using Innovox calcium oxide, quantities of addition will depend on the moisture content. Innovox calcium oxide can be recommended in the foamed extrusion of SBR or Neoprene to improve the call structure and surface finish of the end product. Innovox can retard curing rates when thiazole or sulphenamide accelerators are employed and compounds may have to be reformulated accordingly. In sponge products, calcium oxide can also affect the expansion ratio of the formulation and minor formulation adjustments may be required.”
