Quantity: 100Metric Tons Payment Method: TT, LC INSOLUBLE SULFUR Information Chemical name : polymer sulfur Molecular : Su CAS NO. : 9035-99-8 Executive standard : HG/T2525-2011 Specification Item Index IS7020 OT20 IS6033 OT33 IS8010 IS8510 IS60 IS6010 IS6005 Appearance (Visual inspection) Yellow andnon-risiing powder Yellow powder Yellow andnon- risiing powder ElementSulfurContent% ≥ 79.00 66.00 89.00 95.00 89.00 94.00 Insoluble Sulfur Content% ≥ 70.00 75.00 60.00 62.00 80.00 85.00 60.00 Oil Content% ≥ 19.00-21.00 32.00-34.00 9.00-11.00 —— 9.00-11.00 4.00-6.00 Acidity(H2SO4),% ?≤ 0.05 Loss ondrying(60℃),% ?≤ 0.50 Ash,% ≤ 0.30 Residues on 150μmsieve% ≤ 0.30 High Thermal Stability %105℃*15min ≤ 75 —— Properties: Nontoxic, combustible, yellow powder. As with the S-isomer, said mu-sulfur, high polymerization forms, not soluble in carbon disulfide and other solvents. Mu-sulfur instability can be gradually transformed into cubic crystal-sulfur, a few weeks at room temperature 50% change, as long as 80℃with changes in a few minutes, this need by adding stabilizer to reduce its rate of change. Application: Insoluble sulfur is mainly used in rubber industries, as curing agents make rubber surface spray cream, which will improve the steel-adhesive binding, because the plastic uniform distribution, which would ensure the quality of vulcanization, is the best rubber curing agent, it is widely used tire carcass compound , in particular meridian tires all steel, can also be used for cable, cots, rubber products such as rubber compound. Packing: Polypropylene knitted bags lined with polyethylene bags.Net weight 25kg per bag. Storage:The product should be stored in the dry and cooling place with good ventilation.The packaged product should avoid exposure to direct sunlight. **************************************** HENAN KAILUN CHEMICAL CO.,LTD No.25 Jiefang North Rd, Huaxian, Henan,China E-mail:kailunzhaohui@163.com Mobile:+86-15737242772(wechat&whatsapp) Contact:Ivy Zhao **************************************** |
