Quality Index : Specifications(grade) Wje-96 type 2,5-dimethyl-2,5-di(t-butylperoxy)hexane content: 95—97% Di-tert-butylperoxide content: ≤0.5% Flavour : has no irritant smell Appearance: Yellowish liquid Safe data : flash point (Closed-cup) 42℃. SADT 85℃. Tem 75℃. UN-No 3103. Usage: Ethylene-propylene rubber vulcanizing agent, which can also be used as cross-linking agent for polyethylene and silastic, is of weak odor. Compared with 2,5-dimethyl-2,5-di (tert-butylperoxy) hexane, this agent has better charring performance, higher efficiency in cross linking and slower rate of decomposition, especially applicable to thick-wall articles and large-sized articles requiring low-speed vulcanization. It can be directly mixed with sizing material. Package, storage and carriage: packed in plastic bucket, net weight of each bucket is 20—50kgs,or packed according to client's demands. Store and carry as organic peroxide. Recommended storage temperature 10—30℃.Storage stability as from date of delivery 6 months. It has high purity, tiny admixture.
