  Properties:Light yellow crystal (Granule). The density is 1.17-1.30. Soluble in benzene, toluol, acetone, chloroform, CS₂ partly soluble in gasoline, insoluble in water, acid and alkali with lower concentration. Be sensitive to skin and good storage stability
  
  Application:TETD has similar action to TMTD, but with better scorching property. Due to its low melting point, it has good dispersibility in soft size. TETD is used as peptizer in sulphur-modified chloroprene rubbers.
  
  Packing:25kg plastic woven bag, paper with plastic film bag, kraft paper bag and 25kg drum.
  
  Storage:The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The product with pallet should not be stacked. Stacking of palletized material or temperature of above 35^οC can cause unusual compacted product. The validity is 1 year.
