Easily soluble in acetone; ethyl acetate; methyl chloride; benzene; carbon disulfide, soluble in ethanol; carbon tetrachloride, insoluble in water and gasoline. Exposure to air and sunlight will gradually become grey red.
The product is a natural diene rubber; synthetic rubber; chloroprene rubber and latex for universal type antioxidant. The hot oxygen aging;; flex and general have good protective effect, and is slightly better than that of antioxidant a. Inhibition of harmful metals, but is a weak antioxidant. If 4010 or 4010NA and antioxidant and then, thermal; oxygen; cracking, and ozone resistance were improved significantly. The solubility in rubber is about 1.5%, the normal dosage of 1~2.
