  Properties:Light yellow powder (granule) with a little bitter, no poison. The density is 1.70(20^οC), the decomposable temperature is 300^οC. Soluble in chloroform, acetone, partly soluble in benzene, ethanol, CCl₄, insoluble in gasoline, water and ethyl acetate. Decomposion when meeting strong acid and strong alkali.
  
  Application:ZMBT is mainly used together with ZDMC and ZDEC as primary accelerator for latex; can achieve higher modulus of valcanized latex. In addition, it can achieve good compressive deformation resistance without additional curing time. ZMBT will not affect the stability of latex.
  
  Packing:25kg plastic woven bag, paper with plastic film bag, kraft paper bag, or jumbo bag.
  
  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 validity is 2 years.
