Properties

As a pesticide, this product is usually called fumeishuang. It is mainly used to treat seeds and soil and prevent cereal powdery mildew, smut and vegetable diseases. As a super accelerator of natural rubber, synthetic rubber and latex, it is usually called accelerator TMTD. It is the representative of thiuram vulcanization accelerator, accounting for 85% of the total amount of similar products. As a super accelerator of natural rubber, diene synthetic rubber, Ⅱ, R and EPDM, it is one of the most utilized. The vulcanization promoting force is very strong, but when there is no zinc oxide, it is not vulcanized at all.
