Does anyone know how to deal with the frosting of rubber and how to prevent it?
The reason: if the formula is in before the precipitation of sulfide precipitation may be white, Zinc Oxide or stearic acid, yellow sulfur may be, after curing products, may be white wax, light green or other color may be. The weather is hot, after curing the product easy to spray cream, can properly reduce the antioxidant.
The situation of frost spray often occurs in rubber products, except for formulation reasons and weather. From the stage of occurrence, it may happen before sulfuration or after sulfuration.
To reduce blooming, mainly by adjusting the formula to achieve, such as reducing the amount of antioxidant in summer, storage time is short before vulcanization, if you can consider the use of paraffin wax, microcrystalline wax, if sulfur spray frost can consider changing into insoluble sulfur. Because I don't know your recipe, I adjust it according to the actual situation.
