Properties:Gray-white or light yellow powder(granule) with a little bitter, no poison. The density is 1.45-1.54, m.p.: 166oC. Soluble in chloroform, partly soluble in benzene, ethanol, CCl4, insoluble in gasoline, water and ethyl acetate. Good storage stability.

Application:MBTS has medium curing rate in NR and SR; suitable for most general rubbers; Used as plasticizer and delay agent in chloroprene rubber. It is usually used together with secondary accelerator in the synthesis of polymers; has better scorch safety than MBT.Packing:20/25kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bagStorage:The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years.
