Properties:   White powder.No taste,no poison.Soluble in lower concentration alkali,CS2,benzene,acetone CH2Cl2,partly soluble in chloroform,insoluble in alcohol,CCl4 ethyl acetate.

Applications:  Used for NR,IR,BR,SBR,NBR,HR,EPDM natural&synthetic latexes.Stronger accelerating powerthan TMTD.Strong resistance to scorching.In its handling,care should be operated,because of its increase activation strong tendency to scorch atlow temperatures (100).Often used as a secondary accelerator.In latex,better results are obtained when used in combination with other types such as thiazole accelerators.Used for rubber coated fabrics,latex products rubber cement,etc.FDA approved in USA.

Package:  20 or 25kg plastic woven bag,paper with plastic film bag,kraft paper bag.

Storage:  The product should be stored in thedry cooling place with good ventilation,avoiding exposure of the packaged product to direct sunlight.Since the date of production,the storage period is 24 months.

Notes:  The product could be ultrafine powder based on customer accurate requirement.
