CAS#：110-05-4 Commercial Name: Wjg-99 typeDTBP, weijingDTBP-99 Chemical Name: Di-tert-butylperoxide Molecular Formula： C8H18O2 Molecular weight：146.22 Chromatographic detection Physical Characteristics: Colourless liquid or light yellow transparent liquid . Doesn't dissolve in water, dissolve in organic solventssuch as acetone, methylbenzene etc. Boiling point 111℃(101.3kpa),40℃(7.3 kpa). Melting point－40℃. Viscosity 0.8Mpa.s. Refractive index(20℃)1.386—1.388. Density(20℃)0.788—0.793 g/cm3. Active Oxygen content 10.8%. Half-life (0.1mol/ in benzene): 10 hrs./ 125 oC, 1 hr. / 146 oC, 1 min. / 190 oC. Stable in normal temperature, and not sensitive of impact. Have no corrosion with aluminumand steel, no obvious toxicity, easy to store and carry. Quality Index: Specifications(grade) : Wjg-99 type Di-tert-butylperoxide content： 98—99.5% Tert Butyl Hydroperoxide content： ≤0.1% Appearance： Colourless liquid or light yellow liquid Safe data : flash point (Closed-cup)12℃. SADT 80℃. Tem 75℃. UN-No 3107. Usage: Curing agent for vinyl silicon rubber. Have little sensitivity of acid, but the rubber materials should be controlled at the specific PH value. Its temperature of vulcanization needs to be up to of 140 — 180 ℃ , this value is high ,compared with various peroxides. Its half-life is the longest , but the anti-scorching ability is excellent. Its vulcanization should be adopted press vulcanization technology to avoid porosity. The smell of the vulcanized product is subtle. This product has high vapor pressure, volatilizes easily, and should be used after absorbed by molecular sieve. Package, storage and carriage : packed in plastic bucket, net weight of each bucket is 20- 50kgs,or packed according to client's demands. This product is volatile and flammable, so its storage should be pressure-tight and avoiding fire. Store and carry as organic peroxide. Recommended storage temperature below 25℃.Storage stability as from date of delivery 6 months.
